Construction of a flood alleviation scheme and major events (August 2014) has changed the bed and bank profiles significantly, station will require complete re-calibration.Velocity area station; 50m wide river section. Station located in mobile gravel reach which necessitates frequent recalibration of low flow rating. Occasional ice build-up in winter months. Flows contained under cableway up to 3.8m. Adequately gauged to bankfull. Bypassing of station only known in 1970s by floods above about 4m; since then flood banks have been raised. High flow gauging on the Findhorn is difficult and substantial extrapolation of the rating was needed to compute the exceptional August 1970 peak., but this was substantially exceeded during the 'Muckle spate' of 1829. Three peak flow ratings across period of record, derived from current meter gaugings.Full period of record peak flow data reviewed and released in April 2017 (WINFAP Files v5).

Low flows affected by abstraction for PWS.Velocity area station; about 23m wide section. Flood warning station. Levels recorded from 20/06/58, Gaugings from 01/10/63. Station was moved upstream by 150m from 08/09/78. Old site had no bypassing problems (peak flow record is good) and had a stable rating.The main control is a long and insensitive stone weir 350m d/s. Station experiences significant bypassing (4 times in 10 years) at flows above 2.3m via a depression on the right bank (e.g. July 1997 flow based on rating is 92 cumecs, but additional bypassing estimated to be about 30 cumecs). Cableway rated. Ratings derived from current meter and ADCP gaugings up to 64 cumecs (about 1.3QMED). Flows above this based on modelled floodplain flow. The two peak flow ratings are for pre- and post-1978 when the station was moved upstream.Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Upland headwaters. Bedrock Schists, gneisses with some ORS. Extensive superficial deposits. Some moorland and tree cover in headwaters, arable in valley bottoms. Notable floodplain u/s. No significant catchment changes known.Flows affected by abstraction for PWS - Glenlatterach Reservoir provides supply for Elgin.

Problems with rock/boulder control due to spates. Control has been re-built twice in 1990s. Normal shifting of gravels may slight influence ratings. The river bed was subject to major erosion and scour during floods of September and November 2009. New peak flow rating in 1996, applied from 1953 to the spate of April 1990 (from current meter gaugings up to 1.2m (QMED), simple extrapolation beyond). Post-1990 rating based on few gaugings (up to 0.5QMED) and will need revision.Data post-2009 floods is not held on the NRFA. Mountainous (part of Cairngorms), often snowy in winter. Mountains, moorland, almost no tree cover.Very turbulent flow. Large proportion (>70%) of the catchment developed for hydro-power with major diversions out of catchment.

Velocity area station; section about 30m wide.Cableway rated. Some bypassing at highest flows, which is considered to be insignificant. Previously controlled by long and broken weir, unstable and insensitive, severe weed growth also, hence complicated history of rating changes for medium-low flows. Weir rebuilt in September 1996, less problems with weed growth since and rating has proved to be stable. Peak flow rating derived from current meter gaugings up to 2.1m (2QMED), simple extrapolation beyond. Second edition of peak flow rating was applied after weir control was rebuilt.Granites and older basic intrusives surrounded by Dalradian metamorphics. Almost full superficial deposits cover. A little moorland, but mostly lowland in character with arable agriculture and relatively high population density; some forestry. Notable floodplains.

Series encompasses early data from Cairnton.Velocity area station; about 60m wide section. Flow records for Woodend are an amalgamation from two different stations. Present station (built in 1972) replaced earlier station (Cairnton, located approx. 1 mile d/s from Woodend at an abstraction point - some daily staff readings from 1911, continuous flow records from 1929, chart records from 1934) on same reach. C/m measurements at Woodend initiated by Capt. McClean. Cairnton continued operating until the end of 1984.Cableway rated, fairly stable natural control. Winter low flows can also be elevated by ice. From 1929, rating for Cairnton derived by correlation with current meter measurements at Woodend. From 1934 Woodend used for calculating flows at Cairnton, both stations fitted with chart recorders.

Occasional isolated low flow in winter months e.g. Jan 1960, thought to be due to frozen catchment. Winter low flows can also be elevated by ice, in some cases flows have been reprocessed to correct for this, e.g. Dec 2009.Mountainous headwaters, often snowy in winter. Dalradian and Moinian metamorphics along most of valley, flanked by igneous intrusives. Responsiveness slightly dampened by superficial deposits. Mountain, moorland; forestry, with pastoral and some arable in valley bottom. No significant catchment changes known.Natural regime. No regulation, little natural storage (but significant snow in headwaters), minor abstractions.

Highest gauging station on the Dee.Cableway rated, unstable natural control. Prolonged cold spells cause a considerable drop in flow and on rare occasions ice formation on the control requires estimation of flow. River well contained, no bypassing. Rating derived from current meter gaugings up to 2.3m (about QMED), simple extrapolation beyond. No out of bank surveys have been undertaken at this site by either SEPA or any external contractors. However, recent work by consultants following flooding from Storm Frank (Dec 2015) has suggested modelling should be undertaken to account of out of bank flow at this site as some water bypassed the station flowing through trees on the left-hand bank on the Mar Lodge estate. This may have an impact on subsequent high flow rating reviews but as of 30/10/17 this information is not available. One peak flow rating applied up to 14/08/14, where the channel profile changed significantly during the remnants of hurricane Bertha. The rating is being re-calibrated and no peak flow estimates are currently available post 14/08/14.December 1989 flows estimated due to ice formation. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Upland catchment with mountainous headwaters, often snowy in winter.

Low flows affected by abstraction for PWS.Velocity area station, about 20m wide. Station has cableway and natural control. Flows may be influenced by a fishing jetty a short distance d/s from gauging station. Rating derived from current meter gaugings up to 3.4m (about QMED), simple extrapolation beyond. One peak flow rating has been applied to the entire record. A cableway allows high flow gaugings. There are large man-made stepping stones upstream of cableway that are thought to be a factor in the station control.

Catchment is mostly steep (mountains and moorland), exceptions are lower valleys. Bedrock mainly metamorphics and granite, but the lower catchment (Isla Valley) is ORS. Over half of the catchment is overlain by superficial deposits (mostly Boulder Clay). Landuse is mainly rough grazing and forestry. Several large lochs in catchment (Ericht, Tummel, Tay and Rannoch).Since end of 1957, 1980 sq.km (43%) controlled for HEP. From mid-nineties there may be an influence on flood frequency lower down the Tay due to change in HEP management of levels to accommodate greater storage for flood water. Some control prior to this. 73 sq.km controlled for water supply. Significant winter snow cover.

Removed from peak flows dataset in August 2021 (WINFAP Files v10).Cableway present. Until 1994 an island downstream of the station was high flow control. Island was removed in 1994 by landowner, hence control is now unstable for high flows and backing up occurs which can affect the rating. Bypassing occurs at levels above 3.3m from about 2km u/s - flows bypass on the right bank bend via meadow by overtopping of levees. Ratings derived from current meter gaugings up to 2.7m, simple extrapolation beyond. Data removed from peak flows dataset due to low confidence in flood estimates due to unstable control, hysteresis and bypassing.Naturalised monthly flows available from 1973-1985. High flow data post-1994 is of poor quality due to unstable control and bypassing at the station.Mountainous headwaters, often snowy in winter. Catchment lies on southern edge of Grampians rising above 1000m and has mainly steep slopes. Southern part of the catchment is sandstone, the remainder is metamorphic and igneous. More than half of the catchment is overlain by superficial deposits. Landuse predominantly rough grazing and forestry in uplands, cattle and arable in lowlands. No significant catchment changes known.Significantly influenced by impounding reservoir system of Loch of Lintrathen and Blackwater Reservoirs (supply for Dundee). Appreciable net export.

Straight, uniform channel (concrete walls) lined with gabions; banks are steep to 2.0m. Previously velocity-area station: instability in rating caused by d/s deposition. Prior to weir installation in October 1988, the high flow control was probably d/s bridge, but deposition caused problems. After the weir installation: up to 1.4m stage the flow is modular. Non-modular flow sets in somewhere above this level though not precisely known, partly due to occasional dredging of d/s deposition. Peak flow rating derived from gaugings up to 2.3m.Flows pre October 1988 are not fit for flood estimation and are therefore rejected. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8) and August 2021 (WINFAP Files v10). The upper part of the catchment drains part of the Campsie Fells. Bedrock composed of igneous rocks in headwaters and Carboniferous rocks in the valley; predominantly overlain by superficial deposits. Land use predominantly moorland and plantation forestry in headwaters, pasture in lower reaches. Minimal floodplains. No significant catchment changes known.Flashy response. Catchment contains Carron Valley Reservoir, which pre-dates gauge. Export of water and operation of reservoir can significantly influence flow patterns. Influence of effluent return to Endrick Water on floods is negligible.

Flows affected by lochs within the catchment.Velocity area station on a straight reach with artificially heightened and steeped banks. Removed from peak flows dataset in September 2019 (WINFAP Files v8).The control was formerly a gravel bar, in Sep 1977 stabilised with gabions to form an irregular broad-crested weir. Possible movement in control, evident at low flows. Weir is thought to be modular throughout range. All flows contained to date. Peak flow rating derived from current meter gaugings up to 1.6m (about QMED), simple extrapolation beyond.Mostly low-lying catchment. Bedrock predominantly Carboniferous rocks; predominately overlain by superficial deposits. Land use lowland arable farming, and forest with significant urbanisation. Minimal floodplains. No significant catchment changes known.Relatively un-flashy. There are a number of small storage reservoirs in the catchment plus Loch Leven whose outflow is controlled by sluice gates (these can produce seemingly anomalous flow hydrographs). Effluent return and industrial/agricultural abstractions probably don't significantly influence flood peaks.

A railway embankment forms the rb, whilst the lb is steep to the floodplain at 1.6m. Station added to peak flows dataset in August 2021 (WINFAP Files v10).Stable rock bar low flow control, has shown instability at right bank. Although an open channel, the gradual growth and capsizing of a tree just downstream of the station is a key factor in understanding the stage-discharge relationship. Its evolution is pretty well documented by pictures. Its size and extent to which it slumps in the channel increases through the station period of record until it collapses completely and falls into the channel in February 2020. The impact of the tree is evident in the ratings from 2012, where the second segment parameters are not typical of open channel hydraulics.May 1994 flows affected by work at the Loch Fitty outlet.Lowland catchment in the coal mining area of W Fife. Bedrock Carboniferous rocks, >90% overlain by superficial deposits, mainly boulder clay.

On 06/06/1956 recorder was moved d/s to its current position. An earlier station by the same name existed somewhere upstream from 1939. SEPA holds copies of the chart record from this earlier station but has no details of the exact location, any gauging history, or rating details from the earlier station. Station added to peak flows dataset in August 2021 (WINFAP Files v10).Steep banks of ~3m have contained all recorded floods. Low flow control is long gravel riffle: high flow control is channel geometry, including downstream bend and mid-stream island. Station suffers from occasional ice build up. Single segment rating thus seems counter-intuitive but no evidence in gauging records during any period to suggest multiple segments. No gaugings or ratings available for period prior to 01/04/1970. Catchment rising from near sea level up to ~1150m. Complex bedrock, predominantly impermeable (metamorphic) with approx. 60% superficial deposit cover. Land use mainly grassland and forest. The Teith drains from the Trossachs.Six large lochs in catchment - some supplying water to Glasgow: flows <75%ile elevated above natural and flows >75%ile are less than expected naturally.

As site is within a caravan park the low flow control is susceptible to rearrangement by children.Although GDF data is available from 1971 the station was impacted by land raising for development on the left bank in 1995 which changed the channel geometry: hence peak flow data only available after 1995. A few (relatively low) peak flow values are actually lower than values at upstream station (Kinbuck, 18001) but effect is attributed to in-channel attenuation as flood volumes at Bridge of Allan are greater. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).The Allan Water occupies a broad flat valley with steep lateral tributaries. Bedrock predominantly Old Red Sandstone; ~85% overlain by superficial deposits. Land use grassland with some arable and forest cover. Some minor upstream abstractions but natural to within 10% at 95%ile.

Pictures from the 1970s show that vegetation on the banks was much less during the earlier period of record.Mostly low-lying catchment. Bedrock mixed permeability; ~85% overlain by superficial deposits. Catchment is mostly moorland; some forest and arable landuse.Small reservoirs in catchment have a slight effect on otherwise natural flows.

The station is located on a straight even reach with steep banks containing all recorded floods. Low flow control is a stable bar. The high flow control is likley a bedrock cascade combined with the deep gorge and bridge pillars at Grotto Bridge approximately 600m downstream, providing consistency through the period of record. Peak flow rating derived from current meter gaugings up to 3.3m (about 1.1 QMED), extrapolated above. Gaugings from 1957 not included in derivation of rating.Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Mostly lowland catchment. Bedrock predominantly Carboniferous rocks; predominantly overlain by superficial deposits. Land use rural (grassland, arable, forest), with extensive urban development around Livingston, esp. industrial estates, and several small mining towns. No significant catchment changes known. Possible future change: expansion of Edinburgh Airport.There are three water supply reservoirs in the headwaters (Cobbinshaw, Crosswood and Morton). Low flows substantially affected by sewage effluent esp. from Mid Calder and Newbridge STW and six smaller STWs. Abstraction at Almondell to feed Union canal.

Land use changes may have affected the flow regime.Broad-crested masonry weir of a former pumping station intake works; section about 6m wide. Prior to 1969 the weir was compounded (lower crest 6.1m wide, upper crest 1.45m wide). A sluice gate, which extended the earlier structure capacity by 2.8cumecs, was permanently closed in 1969.U/s from weir, weed growth has constricted approach channel. Containment good on rb, structure full 1.4m corresponds to bankfull on lb and has been exceeded several times during the period of record. No cableway. A footbridge d/s & a metal vehicle crossing 30m d/s maybe high flow control. Peak flow rating derived from current meter gaugings up to 1m (about 0.8 QMED), simple extrapolation beyond.Mainly low-lying plateau moorland (much artificially drained). Mixed permeability bedrock with predominantly superficial deposit cover. Carboniferous limestone, Millstone Grit, Coal Measures.

Original control was a natural bar with large boulders before the installation of the informal Flat V triangular weir. The sluice is thought to be for weir maintenance only and has no impact on the flow record.

Velocity area station in a straight even reach 50m u/s of a road bridge; section about 14m wide. The banks are steep to 2.5m.It is hypothesised that one or both of the two stone single arch road bridges 50m dowstream are/is the main control during large floods, which have been constant through the period of record. The low flow control will be the bed level, transitioning to the bank profile at medium flows and then the bridge(s) at higher flows. The piers of the railway bridge around 0.5km downstream are potentially being influential. The gradient of the 1984 flood level was surveyed in the reach of the railway bridge and it shows significant backing up from the piers, but considering the distance downstream from the station, the local influence of the two road bridges likely preside as the dominant control of flood stage-discharge at the station. There is also a large mill weir downstream from the railway bridge, although it likely not a factor being so far downstream. Changes to bed from scour and deposition during larger floods through the periods is likely and there is photo evidence of greater vegetation growth on the banks and possibly bank slumping in more recent years. Such change to the bed and banks will become less significant with higher stage. Two peak flow ratings across the period of record, pre- and post-1967.Peak flows rejected 01/10/2016 to 30/09/2017 due to flood defence construction words. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Catchment with mix of lowlands-uplands; headwaters in the Pentland Hills. Bedrock permeable with predominantly superficial deposits. Lower part of the catchment has undergone urban development; the upper part contains mainly moorland, arable and forest landuse. On-going urban development particularly in 1970s. Dense urban development in lower catchment. Narrow long catchment. Extent of floodplain storage is unlikely to exert a major influence on flood regime. Catchment contains 3 storage reservoirs in headwaters (Harperrig, Threipmuir, Harlaw). They are no longer used for water supply and Threipmuir has a target seasonal level regime for wildlife management. Proposed drawdown levels are being discussed (2002/03) for flood alleviation purposes. Union Canal runs through lower catchment though it is not likely to influence flood regime significantly. 150 combined sewer overflows in urban reaches. Relatively impervious and flashy.

In extreme flows, control of bridge diminishes and control becomes d/s channel & footbridge. Flows abstracted u/s of the main station along a mill lade were monitored (until late 1980s) - summation needed to give total basin runoff.

Peak flow rating derived from current meter gaugings up to 2.5m (about 1.8 QMED), simple extrapolation beyond. High rating appears to oscillate with periodic dredging (a problem in the past) and accretion of a bar on the rb. All flows to date contained.Historic flooding occurred and is manifested in markings on Inveresk Mill (e.g. 13/08/1948 7.37m, 21/09/1891 6.99m), about 1m above bankfull.Catchment with mix of lowlands-uplands.

Some small reservoirs in headwaters that are drawn down for flood prevention.Compound Crump weir without a cableway. Removed from peak flows dataset in August 2021 (WINFAP Files v10).Flows were originally measured by a Crump profile weir and trapezoidal flume in parallel. The flume suffered from choking by domestic refuse and children's dams and so was replaced in Oct 1985 by a second Crump profile weir d/s of the first. Culverts present about 300m d/s and may back up in flood situations. Theoretical rating with current meter gaugings up to 0.4m (0.4 QMED). Changed after new structure built in 1985. Possible new hydraulic model rating once flood prevention scheme complete. Crump weir can be affected by deposition when only the lower crest is in use (but this clears once the higher crest is also in use). Data removed from peak flows dataset due to very poor confidence in peak flows as essentially designed and operated for low flows - no flood gaugings, backing up from downstream culvert and poor containment.Flows during the flood prevention works are still under review and therefore not held on the NRFA.Mostly low-lying catchment with the headwater tributaries steeply rising in the Pentland Hills. Complex bedrock geology - Silurian/Devonian sedimentaries and igneous intrusions; with half overlain by superficial deposits. The lower part of the catchment is extensively urbanised. There are several small reservoirs in the headwaters with forest and some arable landuse. Progressive urbanisation.Flood prevention works affected the site (completed in 2011). Torduff, Clubbiedean and Bonaly are small reservoirs in headwaters that are drawn down for flood prevention. Combined sewer overflows discharge into the stream.

Built to measure compensation flows from reservoirs in the Lothian region; these dominate the summer hydrographs. Both SEPA and Scottish Water measure here.Flows fully contained in vertical channel walls. Uses theoretical rating (confirmed by gauging). The station is gauged by wading up to 0.5m, ADP gauging is carried out at higher levels from a bridge ~500m downstream. There is a small inflow channel upstream of the weir (right bank) which can input at high flows and cause a bit of turbulence. There are no problems with weed growth at the station. Catchment is almost entirely rural. The SW edge of the catchment is steep (Pentland Hills) rising to over 500m; the rest has moderate slopes. Bedrock predominantly permeable with ~85% superficial deposit cover. Land use grassland and arable with some forestry and two major reservoirs.Regime affected by Water of Leith flood prevention scheme.

Further d/s of the station the river turns a 90 degree bend at the Edinburgh Airport runway just above the confluence with the River Almond. This can back-up at high flows and flood parts of the airport. The river tends to flood u/s of the station with consequent damping of its hydrographs.Small low flow control and large masonry broad crested weir controlling higher flows. A good site, although an issue of gauging at low flows due to low velocities in the channel; this has been improved by gauging with a Flow Tracker instead of propeller current meter. Station gets silted up so needs regular flushing. There is regular weir cleaning to keep it clear.Exceptional peak flow in April 2000 followed storm totals exceeding 80mm.Lowland catchment. Bedrock permeable with >95% superficial deposit cover. Catchment includes part of Edinburgh, and the urban fraction is increasing. 1.5km of the river has been culverted because of new development. The remainder of the catchment is mainly arable, grassland, and forest.Small net impact on runoff due to airport discharges.

In 1970 a pipe crossing was constructed but did not unduly influence the rating. Road bridge 200m d/s provides a stable high-flow control: pre-1982 clear span bridge; post-1982 double box 'culvert' shaped. Allowance is made for weed growth during the summer when abstraction for irrigation also takes place. Corrections made to rating for weed in summer before 1965. Peak flow rating pre-1982 is derived from current meter gaugings up to 3.026m (about 2 QMED), simple extrapolation beyond. The Peak Flow data is validated by flood gaugings up to the bridge rebuild only, which is an unknown date in 1982. As this bridge acts as the flood control, a new relationship is required post bridge rebuild. However, there have been no flood gaugings after 1982 and critically the current rating does not have a segment after 2m where there is a step change in the bank profile. Therefore updates form 1981 are not possible until flood gaugings and/or flow modelling is carried out.During 1982 recorded stage was adjusted during rebuilding of the road bridge 200m d/s.The catchment is characterised by steep headwaters in the Lammermuir Hills and broad flat valleys. Bedrock Silurian and Ordovician sedimentary rocks; predominantly superficial deposit cover. Land use mainly arable in the valleys with grassland in the headwaters. No significant catchment changes known.Low flows affected by sewage effluent and abstraction for irrigation d/s of Haddington. Significant floodplain storage throughout lower reaches believed to influence flood frequency curve.

Since 15/09/1967 flows have been measured by a trapezoidal flume and Crump profile weir (crump crest at 0.445m above flume invert) in parallel. The section is within steep banks on a straight reach of a small ditch with low gradient (no cableway). Removed from peak flows dataset in September 2019 (WINFAP Files v8).Low flows are severely reduced by both groundwater and surface water abstraction for spray irrigation during dry summers. Pre-1968: theoretical rating or stages up to 0.914m; high flow calibration is not reliable. From 1968: theoretical rating, confirmed by gaugings. Modular probably to 0.757m - then kink point in rating curve. Bankfull around 2.2m. Primarily a low flows structure with limited high flow gaugings and variable backwater effects. Lowland catchment draining flat arable land. An impervious catchment with an extensive Boulder Clay cover. Agricultural drainage has possibly changed and improved over period of record.Channel is known to be dammed upstream which can affect the flows.

The channel reach is within steep, high flood banks which contain all floods in record. Flows from this station are used as part of the Haddington flood warning system.In September 1975 an irregular broad-crested weir was installed (concrete-topped gabion weir with a V notch to increase sensitivity at low flows). Non-modular for high flows, weir drowns out. Before that date the low flow control was a gravel bar. The gauge board was lowered by 0.125m on 1/9/1969. Two ratings (before and after gabion control installation in 1972) both derived from current meter gaugings, simple extrapolation beyond. Rating revised in 2016. Some issues with fungal growth on the weir, but it is maintained regularly.Full period of record peak flow data reviewed and released in April 2017 (WINFAP Files v5).The headwaters drain exposed moorland of the Lammermuir Hills. Bedrock mostly impermeable predominantly overlain by superficial deposits (thin soils). Silurian/Devonian sedimentaries. Land use predominantly arable with some forest. No significant catchment changes known.Flashy response. Low flows are affected by industrial and agricultural abstractions.

The recorder is sited immediately d/s of a footbridge on a slight bend in a natural channel.The low flow control is a stable rock bar. The likely high flow control is a bend in the channel. One ratings derived from current meter gaugings, simple extrapolation beyond. Rating revised in 2016. There are some issues with velocity drawdown from the inlet pipe at the station, a stilling chamber was constructed but has been washed into the channel and needs to be replaced. The inlet pipe can also become blocked at low flows.A large tree fell into the channel and was present between late 2013 and early 2014, causing possible gravel accumulation (resulting in lower flows from higher levels). Tree removed in early 2014, but low flows from then to present are suspect due to uncertainty in rating. Full period of record peak flow data reviewed and released in April 2017 (WINFAP Files v5).Mostly low-lying catchment with headwaters rising quite steeply. Bedrock predominantly Silurian and Ordovician; predominantly overlain by superficial deposits. The catchment drains the steep moorland slopes of the Lammermuir Hills. Arable land use dominates the lowlands with some forest. No significant catchment changes known.The flow regime is natural and flashy.

The primary control is a gravel shoal (~100m) below the station that is prone to adjustment during floods. A ford 200m downstream and a mill weir 650m downstream may be an influence on the stage discharge control at higher flows. Bypassing can occur on left bank at levels above about 2m, although this is thought to account for less the 10% of flows during extreme events. Frequent re-rating due to weed growth, but only two ratings are required across the period of record for peak flows. Gauged up to QMED with simple extrapolation beyond.October 2005 event was exceptional. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8). Natural upland catchment. Bedrock mostly Silurian shale; predominantly overlain by superficial deposits. Hill grazing is the dominant land use but forestry is important in the headwaters (Craik Forest). Hawick is the only significant settlement. No significant catchment changes known.Natural regime.

Gravel bed with control formed by concrete haunching over sewage pipe. Control was repaired and heightened by 120mmm on 01/08/68, hence the rating change on this date. The station reach is straight with well defined banks.The channel cross section at the footbridge is slightly narrowed and this will likely be the primary control during large events. There is some confidence in extrapolating flows up to bank full at 2.5m considering the channel is well defined and the highest gauging is at 1.862m (measured flow of 83.7 cumecs). The dervied flow at 2.5m using rating QHigh1968 is 144.54 cumecs. Only the AMAX1 in 1982 was higher than bank full, but only marginally and floodplain flow would have been negligibly. The 1982 flood would have hit the footbridge and this may have impeded the flow. There is also the possibility that woody debri was trapped on the bridge during the event. The station hut, well and ramp gauge was completely rebuilt in 2016 following works to reinstate the Waverly Railway line. The control (concrete haunching over pipe) was compromised by bank erosion on the left hand side and this was repaired in 2016. As of October 2017, the control is in a bad state with concrete apron breaking up and water starting to undermine it.Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7). The weir repairs warrant a new rating (pending gaugings) so record is currently frozen from 2015.Natural upland catchment draining from the Moorfoot Hills.

Water surface can freeze in winter.Velocity area station (section ~10m wide).Artificial control consisting of a flat concrete bar with stone pitched banks. The historic rating record suggests the weir was constructed on 30/06/69. If the station operated before this date, its assumed it was as a natural open channel control. The site is situated at end of straight reach with a bend just below a bar. Water surface can freeze in winter necessitating ice corrections. Bypassing occurs at higher flows on the lb. Peak flow rating derived from current meter gaugings up to 1.1m (about 0.8 QMED), with a simple extrapolation beyond. Since the 90s the site has only been gauged up to 0.6m/10cumecs. The channel suffers from bank erosion and upstream erosion is thought to have increased the amount of bypassing during large events. The increased channel instability was likely triggered by the large flood of 30/12/15, known as Storm Frank. The weir has also become badly eroded. Considering the bank/weir erosion and the lack of high gaugings, there is little confidence in flows above QMED.Monthly naturalised flows available. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).Steep upland catchment developed on Silurian shale, some of which is overlain by superficial deposits. Land use mostly hill grazing; some forest. No significant catchment changes known.Runoff is slightly diminished by an u/s abstraction (Langhaugh Intake). Very responsive catchment.

Velocity area station. Wide section (about 100m) on gentle bend in river. New cableway (2003) can gauge flows up to 4.35m stage.The station is affected by seasonal weed growth effects and seasonal ratings have been adopted for low flows. There are remnants of an old mill weir 200m downstream as well as a more prominent mill weir 2km downstream. Both of these weirs will influence the station control at medium to high flows at least, but likely drown out during larger floods. Flows are largely contained or are at least within the range of the cableway reach. The peak flow rating is derived from gaugings up to 4.015m. The 4.015m gauging was on 20/11/2009 and had a measured flow of 1059 cumecs.Monthly naturalised flows available. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).A mix of upland and lowland. The bedrock geology is dominated by impervious Silurian formations (with some deposits). Hill grazing predominates with improved grassland and arable farming in the lower catchment; some forest in headwaters. Some reservoirs in the headwaters were established during the period of record (Fruid Reservoir 1968, Megget Reservoir 1982).Public water supply reservoirs in headwaters have a minor impact on the flow regime.

Station closed September 2010.Informal flat-V weir and velocity-area station beyond (1:2 and 1:5 slopes and about 1:100 cross-slope, insensitive). V is lop-sided as left wing wall was moved inwards after flood damage. The weir crest has been eroded in the past. Station closed in September 2010 following repeated breaches of bank. Equipment removed.Banks are double terraced, with first step at 1.6m, second at 2.6m. A flood bank on the right bank protects the floodplain, but at high flows there is significant bypassing of the cableway (starting at 1.6m), leading to considerable uncertainty, true peaks not recorded. Flood bank breached in September 2008. The bank was repaired in November 2008 but breached again in July 2009. Partially repaired by plugging the gap with gravel but again breached in September 2009. Station rated by current meter gauging up to bankfull (1.6m). Multiple peak flow ratings applied across period of record, the most recent is valid from June 1989. Flood Studies Report grade A for structure, but C due to chart record.Flows from 1989 reprocessed in 2002: low flows increased, some peak flows decreased. Flat-top hydrographs before September 1966 due to silting of inlet pipe. September 2008 flood caused breach in flood banks, resulting in missing flows until late October 2008. Logger installed in 1991 (very limited data 1983-1990 but charts available). Caution needed in interpreting suspect 1994 minima.Upland catchment, draining from The Cheviot with a natural flow regime. Developed mostly on impermeable igneous formations, around a third of the catchment is overlain by superficial deposits. Around half the catchment is grassland, with mountain/heath in upper reaches and arable in lower lying areas.Natural flow regime, no abstractions.

A temporary station was established 200yards d/s during weir construction, to maintain continuity of records. Inlet pipe and instrument building both replaced in 2006. The station replaced an earlier station at Guyzance, 3 miles u/s.Fairly straight section with high banks, although may be some limited bypass at high flows. Non-modular at even moderate levels. Station has suffered from inlet pipe lag and previously had a gravel trap in inlet pipe. New inlet pipe installed in 2006, no gravel trap. Two peak flow ratings applied across period of record, the most recent is valid from 1976 and based upon an earlier version of rating C but with an additional upper limb informed by hydraulic modelling. Good fit to gaugings. Flood Studies Report grade A1.Data missing 18/02/2006 - 14/06/2006 due to station rebuild. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8). Possibly suspect flows 19/11/2019 - 2/03/2020. Predominantly upland catchment draining from Cheviots. Largely Carboniferous Limestone and low permeability Devonian Igneous series, two thirds of the catchment is overlain by superficial deposits. Half the catchment is grassland, some upland afforestation and arable in low-lying areas. Progressive afforestation and associated drainage on upland Cheviot tributary valleys. Responsive natural regime. In the past annual flush and drain of dam u/s of gauge on Duke of Northumberland estate has affected the flow regime. Some abstractions.

Site closed in 1980.A standing wave flume with broad-crested side weirs separated from the flume by substantial divide walls, flared at the u/s ends; overall width 8.8m. Beneath a road bridge with soffit at 2.2m. River valley is narrow and steep-sided at this point, with rocky bed. Site closed in 1980, reopened in 1999 as level-only flood warning site.A gravel accumulation problem (notably severe in 1977) was partly alleviated by installation of a gabion gravel trap u/s in 1952, cleaned biannually. However, accumulation continued, and the trap collapsed in 2000. Side weirs drown at high flows. No bypassing. Multiple peak flow ratings applied across period of record, the most recent is valid from April-1979 after gravel shoal developed. Flood Studies Report grade C due to uncertainty in rating.Excessive gravel accumulation caused breaks in the early record but installation of a gravel trap in 1952 contributed to increased reliability; almost a continuous record 1957-1980 (when station decommissioned). Data from 1947-1966 from flow recorder with limit of 26.3 cumecs, therefore no floods recorded.A very responsive catchment with small floodplains all the way up the catchment accommodating some over-bank storage.

Thin-plate weir with 6.2m wide centre crest and two flanking broad crests of differing widths (0.85m right bank, 2.2m left bank). Discontinued in 1980 and weir plates removed. Recommissioned as a level-only station in 1995 for flood warning using concrete broadcrested weir with notch. Weir plates reinstated in September 1999. Good d/s drop over the weir prevents drowning.No bypassing. No cableway, gaugings only possible at low flows. Two peak flow ratings applied across period of record for pre-1995 and then post-1999 following reinstatement. Based on theoretical rating of thin plate weir with check current meter measurements at wading level. Rating updated in 2008 and applied back to 1999 when weir plates reinstated. Flood Studies Report grade D pre-1966, A1 post-1966.Gaps in the record occur due to inaccessibility in winter and incomplete flow measurement at very high flows. Peak flows are rejected since the site re-opened and weir plates installed in 1999 as the top end of the rating is not yet reliable. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Small upland moorland catchment draining from The Cheviot.

Record combines data for 22005 and 22007.Velocity area station. Flat V weir and central flume for low flow measurement (3m wide, overall width 18m) installed 1974, replacing older broad-crested weir also with central flume (located above Tynemouth Corporation intake). Cableway. Just below the station, the channel is confined in deep, steep-sided valley at bend in river. The data series for this station (22007) combines records from Highford (22005) from February 1963, replaced by Mitford from November 1966. In the early period, medium and high flows were measured 0.5 miles d/s at Highford Dam. This had an autographic recorder from February 1963-September 1968, replaced by a punched tape recorder until October 1975. The station was never properly calibrated by gauging, but flows were derived by correlation with Mitford.Cableway allows for high flow gauging, but wading behind the hut is also necessary at highest levels. Multiple peak flow ratings applied across period of record, the most recent is valid from December 1975 post weir modifications. Ratings in good agreement with respective gaugings. Recalibration of peak flow rating produced substantial reduction in flood flows. Flood Studies Rating grade A1.Data 17/09/2014-07/10/2014 affected by fish pass installation and eel pass repairs. No AMAX rejected as a result of flood storage dam, but some impact on Jan 2016 event, see event comment. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).A mainly lowland catchment located on moderately permeable Millstone Grit and Upper, Middle and Lower Limestones with extensive boulder clay cover. Around half the catchment is grassland, mixed arable and woodland. No known catchment changes.Font Reservoir impounds 30.3 sq.km of upper catchment on River Font tributary and affects flood flows through drawdown and attenuation. Modest net effect of export from headwater reservoir. Completion of Mitford flood storage dam in April 2015, impounding ~60% of the upstream catchment. This reduces downstream flow in large events, beginning to impact at around 1:25 year return period, with increasingly significant impact on more extreme events. Outflow from the dam is constrained at 150m3/s. The catchment produces sharp hydrographs, but shows a bigger lag than is typical for the area. Northumbrian Water's PWS abstraction at Mitford (just d/s of gauging station) closed by the mid-1990s.

Flow regime influenced by releases from Kielder.Principal gauging station on the Tyne. Velocity area station with cableway on a wide reach. Blockage/damage to stilling pipe caused problems in early 1990s. Removal of gravel from d/s river bed between 1961 and 1963 affected water levels, leading to replacement of stilling well at lower level; high flows relatively unaffected.Before 1961 and after 1964 station considered good for high flow measurement. Ratings have changed over the record owing to alterations in control and bed levels resulting from gravel extraction. Three peak flow ratings for the period of record. Ratings fit well to corresponding gaugings. Flood Studies Report grade A1 before and after 1962-65, B during.As a result of re-rating after gravel extraction the October 1967 flood is now thought to have been lower than the January 2005 peak of 1370 cumecs. Rating C applied in September 2013 resulted in reduced flows (from 1992 onwards), especially at low levels. Rating D applied following December 2015 event, same as previous rating but modifies and extends the top limb above 1130 cumecs. Gauged to very high level, including floodplain flow estimate, in December 2015 event and confirmed by hydraulic model. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).A large, impervious catchment (largely Carboniferous Limestone) with extensive superficial deposits (peat, boulder clay, alluvium) draining from north Pennines. Includes Kielder Reservoir which controls 241 sq.km of the catchment (impounded 1982). Around half of the catchment is grassland, with extensive moorland arable farming confined to the lower valley. There has been significant afforestation in the catchment since 1926.Some export of water, and regime influenced by pulsed hydropower releases from Kielder, but limited impact on annual runoff. In drought years, Kielder releases maintenance low flows (4.2 cumecs min.) and support transfers to the Derwent, Wear and Tees which are abstracted at Riding Mill 500m u/s.

Replaced earlier station at Barrasford (23015) which was unreliable.Velocity area station with natural channel control, some out of bank flow in very big events but no by-passing. Subject to regulation from Kielder reservoir since 1980. Rating fitted to current meter gaugings at on site cableway, gauged to within 30% of AMAX1, some spread in gaugings but generally good fit and extrapolation is reasonable. Flood Studies Report grade A1. One rating applied over period of record.NULLA very responsive upland catchment. Developed mainly on formations of the Carboniferous series (Fell Sandstone, Scremerston Group and Lower Limestone), around half of the catchment is overlain by Boulder Clay and peat in the headwaters. A predominantly natural regime until construction of Kielder reservoir (impounded 1982) which controls 24% of top of North Tyne catchment. Land use is rugged moorland and upland pasture, with significant afforestation in the west of the catchment since 1926. Pre-reservoir FARL is 0.993 and should be used with the pre-reservoir part of the records. Post-reservoir FARL is 0.936.Kielder Reservoir impounds approximately 24 per cent of the catchment to Reaverhill, flow regime is impacted by regulation releases to support downstream abstractions in dry weather and by regular releases of between 3 and 16 m3s for hydropower generation. Hydropower releases have little influence on high flows, however reservoir does have a significant impact on flood flows due to drawdown and attenuation. Catcleugh Reservoir also in the catchment, impounds 40 km2 in the headwaters of the Rede catchment with some net export of water from here to support Colt Crag and Hallington reservoirs.

Catcleugh, Colt Crag and Little Swinburne reservoirs influence flow regime. Station closed 1959. Velocity area station for flows above 6.8 cumecs, in channel approximately 55m wide. The station was originally intended for assessment of flows at the Barrasford abstraction and not for flood flows. Station closed in 1959, replaced by Reaverhill (23003) approximately 2 km upstream, however POT data extracted for Barrasford until 1971 (before Kielder reservoir impounded in 1982). Standing wave flume at Barrasford pumping station, flows between 3.2 and 6.8 cumecs from continuous recorder, flows below 3.2 cumecs calculated from a daily 9 am gaugeboard reading. Flows above 6.8 cumecs measured at open channel section 820m downstream. Rating at Barrasford was only considered reliable up to 4000 cusecs (113 cumecs) and only gauged to 1800 cusecs (51 cumecs) with significant extrapolation beyond. Rating later improved by correlation of stage data between Barrasford and Reaverhill together with flow data from that station (FSR grade B), however considerable inconsistencies remain between peak flows listed for these two sites during the overlapping period.Very low flows below 3.2 cumecs only available from daily 9 am gaugeboard readings. Peak flow rating from current meter gaugings, originally extrapolated at high flows but later re-worked by correlation with Reaverhill (23003), however inconsistent peaks including missing peak 08/12/1964 (rank 2 event at Reaverhill), therefore peak flows rejected for this year. Abstraction at Barrasford pumping station taken between the flume and the rated section, station file notes abstracted volume added to flow measured at rated section when pumping (maximum 22.3 cusecs (0.63 cumecs)).A very responsive upland catchment developed mainly on formations of Carboniferous series (Fell Sandstone, Scremerston Group and Lower Limestone) and is of moderate permeability. Land use is rugged moorland and upland pasture, with a very high proportion of forestry (over a third) for a catchment of this size. Pre-reservoir FARL is 0.989, post-reservoir FARL is 0.934. No known catchment changes.In many winters flow was affected by freezing in the catchment, resulting in very low flows and considerable lag between precipitation and run-off. Catchment includes, Catcleugh (in headwaters), Colt Crag and Little Swinburne (both in south-east of catchment) reservoirs. Abstractions for Newcastle-upon-Tyne water supply do not pass the gauging station.

Early POT and AMAX data recorded at Walter Wilson in Team Valley Trading Estate.Velocity area station in culverted section below road bridge, low flow control is the concrete invert of the culvert. Ultrasonics installed 1998. Peak flows only are provided for 1975 to 1990, recorded at Walter Wilson in Team Valley Trading Estate in straight, engineered section with clay banks and silty bed. Control was channel structures d/s of A692 bridge and pipe crossing. Construction of the 1990 Gateshead Garden Festival site lowered the bed level, exposing the inlet pipe, and the station was temporarily closed.Low flow control exercised by pre-existing weir. Uncertainties in the peak level recorded in the June 2012 event led to a survey of the site to establish when overtopping into adjacent field occurs as the highest peak levels are all very similar at around 1.3m. Ultrasonic installation providing full calibration in 1998 (deactivated April 2005). One peak flow rating applied across period of record in April 2004 based upon ultrasonic data. Analysis of uncertainties in the ultrasonic rating calculation suggests the lower and upper bounds for QMAX are -10% and +8% at this site. Previous peak flow rating was theoretical supplemented by current meter gaugings.Missing AMAX data for 1990 due to construction of Gateshead Garden Festival Site. Daily flows for period of record reprocessed in 2002. Dropouts throughout the period of record (for example, in April, July, September, October & November 2014, July 2015, September 2019, March & September 2020) thought to be caused by reductions in minewater pumping at Kibblesworth (1 mile upstream).A primarily rural catchment on the SW edge of Gateshead, on moderate permeability bedrock overlain with extensive boulder clay and some alluvium. Land use is mixed agriculture with extensive urbanised areas, industry and former coal mines in lower catchment. No known catchment changes.Sewage effluent and pumped minewaters affect the very responsive regime.

Informal flat-V weir (3m wide). Station moved after the building of the Metro underground line and supplemented in October 2001 by ultrasonic measuring equipment (removed 2007).Structure drowns at moderate flows and wing walls overtopped 2-5 times per year. Ultrasonic installed in 2001 to calibrate peak flows (removed 2007). Ultrasonic equipment produces good record with no drop-outs. Analysis of uncertainties in the ultrasonic rating calculation suggests the lower and upper bounds for QMAX are -17% and +44% at this site. Three peak flow ratings applied across period of record. Rating pre-1991 (before Metro line built) established from current metering. Post 1991 rating derived from ultrasonic data and refined in June 2003 to align with more recent high flow gaugings. Current rating (from June 2003) is a composite: theoretical weir equation used below 0.34m and ultrasonic data from 2003-07 plus check gaugings used to derive the rating at higher levels. There is uncertainty regarding the modular limit of the structure, possibly due to weed/vegetation growth downstream and there are few high flow gaugings.Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7). Small (9 sq.km), relatively low-lying catchment on moderate permeability bedrock, but with significant Boulder Clay cover. Predominantly arable with some grassland and around a tenth of built-up area. No known catchment changes. Responsive natural regime with no known artificial influences.

Flow regime influenced by Burnhope reservoir.Compound Crump profile weir located in a steep rocky section, overall width 19.1m, central low crest width 7.6m, Larinier fish pass completed August 2018. Wing walls raised in 1967. A temporary cableway was used d/s of the weir in late 1960s-early 1970s.Weir suffers periodic upstream gravel accumulation, formerly limited by a gravel trap, now ineffective. Flows contained on left bank up to 3.1m until July 2007 when the left wing wall was repaired and raised. Instruments originally on right bank but poor for measuring low flows due to sand and gravel deposition. Instruments moved to left bank from mid-1990s but stilling well thought to suffer from drawdown at high stages >1.5m. A second instrument was reinstated on the right bank in 1998 to improve measurement at high flow but left bank gauge remained the primary data until Feb 2002, when reverted fully to the right bank. In July 2007 the inlet pipe was extended by 2m to improve measurement at low levels due to the accumulation of gravel around the pipe. Two peak flows ratings applied across period of record, pre- and post- fish pass construction (2018), refined using hydraulic modelling. Model gives confidence in rating performing well at high flows. Flood Studies Report grade A1.Bypassing on the left bank affected flow events in 1995, 1999 and 2005. Flow of January 2005 event may be underestimated due to problems with gravel build up blocking the inlet pipe to the stilling well affecting level measurement. Weir repair and fish pass works commenced September 2017 resulting in inaccurate flow data until August 2018. Various periods of suspect flows throughout the record as a result of measurement problems due to gravel deposition and drawdown at high flows. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).Steep Pennine catchment. Mainly Lower Carboniferous Limestone, overlain by peat in headwaters and boulder clay and alluvium in valley. Some forestry but around three quarters grass pasture and moorland and some arable farming. No known catchment changes.Very flashy response and extremely peaked flows. Burnhope reservoir (catchment area 19 sq.km) has noticeable effect; net export of water.

All crests are 0.3 m long in direction of flow. Divide piers inserted and wing walls raised in 1968. Two flight Larinier pass (600mm wide with 100mm baffles) installed in a by-pass channel on the left bank Aug-Sep 2016.No cableway but some boat gaugings carried out. Theoretical daily flow rating with check gaugings. Multiple peak flow ratings applied across period of record. Originally rating theoretical and refined when piers and wing walls altered (1968). A temporary rating is applied between 30/01/1990 and 04/02/1990 whilst tree stuck on weir. The fish pass has a separate stage measurement gauge and rating, flows will be calculated by addition of the weir flow and the Larinier flow from their respective rating curves. Flood Studies Report grade A1.Minewater discharges stopped in 1997 which has affected homogeneity of low flow record; record 2003 low flow sequence, whilst in a notably dry period, eclipses previous minima. Engineering works 28/10/1988 - 21/11/1988: daily flows removed from NRFA. Low flow drop outs in September 2016 are beyond the limits of the rating but may also be a result of engineering works on a fish pass.Coal Measures with just under half the catchment overlain by superficial deposits (mainly Boulder Clay). Half land use is improved grass pasture, with some woodland, and arable in lower-lying areas. No known catchment changes.Minewater discharges influence low flows and create distinct diurnal pattern although impact on annual runoff is limited.

Two peak flow ratings applied in period of record, the most recent is valid from May 1991, subsidence of weir is suspected. Gauging by cableway to flood levels, rating curve fitted to check gaugings.Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Predominantly upland Pennine catchment on mainly Carboniferous Limestone and Millstone Grit, with just under half the catchment overlain by superficial deposits (Boulder Clay and peat). Nearly two thirds grass pasture, with extensive moorland in headwaters, mixed land use in the lower valley. No known catchment changes. Catchment contains Burnhope, Waskerley and Tunstall reservoirs (total direct catchment area 45 sq.km), and has a net export of water. Transfers by Kielder Tunnel from the Tyne catchment are made in drought years, entering the River Wear at Frosterley.

Flow regime influenced by reservoirs, abstractions and minewater discharges.Flat V weir in 33m wide channel, close to tidal limit of Wear but this is not thought to affect the tailwater level.Non-standard flat V weir (1:2, 1:2 profile, 1:40 cross-slope), becomes non-modular at moderate flow and fully drowned at high flow. Spills onto wide left bank floodplain above 1m stage, floodplain gently rises for some distance before flattening off but largest peaks cover much of the recreation grounds between the river and the A167 dual carriageway. One peak flow rating applied across period of record, checked by gaugings from upstream bridge to 3.8m stage (330 cumecs)(within 15% of AMAX1) with fairly stable extrapolation. Flow is not affected by tidal limit downstream. Vertical tile eel pass installed in 2015.Gaugeboard survey in 2013 identified historic error between 06/2000 and 09/2013, levels in this period lowered by 36mm and flows re-processed. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).Carboniferous Limestone and Millstone Grit, with over two thirds of the catchment overlain by superficial deposits (mainly Boulder Clay). Land use half grass pasture, moorland in Pennine headwaters, arable and built-up areas in lower valley. No known catchment changes.Peaks of very large events are flattened. Reservoirs in catchment include Burnhope and Tunstall. In drought years low flows supported by Kielder transfer (flows maintained >2 cumecs). Abstraction for Wearside water supply is downstream of gauging station at Lumley. Also affected by minewater discharges (regime has changed since pit closures). Artificial influences created a distinctive diurnal variation, especially at low flows, until 2004.

Heavily influenced by reservoir storage, abstractions and discharges throughout the period of record.Compound Crump profile weir with total crest length of 63.9m. Two low-flow crests total 9.1m. Gauged ultrasonically from 2002 but this was abandoned in 2011 due to poor performance. D/s level measurement installed 2003. No changes to control since construction apart from fish pass (1992-1993) inserted in low flow weir. There have been bank breaches in the past, and the right bank overtops into Cleasby washland at around 2.5m stage.Modular up to approx. 2.5m. Hydraulic modelling suggests up to 20% bypassing flow at > 100 year return period. Single peak flow rating applies across the period of record, extrapolated using hydraulic model. Flood Studies Report grade A1 for all except one occasion.Three peak events (1986, 1995 and June 2000) have stage values within 1mm as a result of overtopping; evidence suggests 2000 was the highest and may have been 25-30% higher. 1959 minimum may have been influenced by abstraction immediately u/s. New rating developed in September 2014 and applied from 1982 onwards, reduced flows for the highest AMAX events. Historic daily mean flow data from 1956 - 1981 has not been reprocessed. Drop in flows 03-16/05/2017 caused by draw down for essential maintenance at Cow Green Reservoir. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Predominantly upland catchment, headwaters draining the Pennines. Mainly Millstone Grit and Carboniferous Limestone (sandstone, shale and limestone facies), with the majority of the catchment overlain by superficial deposits of peat and Boulder Clay. Moorland and rough pasture give way to more intensive agriculture in the lower reaches. No known catchment changes.Significant export of water from direct supply reservoirs (six reservoirs with a total area of 180.7 sq.km totalling 22.1% of catchment) progressively influencing during record period (Selset 1960, Balderhead 1965, Cow Green 1970). Cow Green operation includes winter flood storage drawdown, and river regulation to support abstraction and statutory minimum flows. U/s abstraction for industry during 1960s subject to a minimum 5MGD passing weir; continued until Balderhead Reservoir completed. Significant export of water from direct supply and abstraction u/s. Some regulation from Cow Green Reservoir. Import from Tyne via Kielder Tunnel in exceptional drought years.

Data presented for the present structure, from water year 1962/63.U/s shoaling and low winter temperatures affected precision of flows. Multiple peak flow ratings applied across period of record, the most recent is valid from January 1991 when station decommissioned.Severe winters in 1963 and 1979 caused the river to freeze resulting in a flat float trace. Missing data 19/08/2001-09/11/2001 due to lack of access due to foot and mouth disease, logger data overwritten and lost as a result of the rolling memory. Missing data 07-21/01/2003 due to telemetry issues.

Flow regime influenced by reservoir, minewaters and sewage effluent.Compound broad-crested non-standard weir, not purpose built but unlikely to drown. On low-lying ground, formerly the floor of a boating lake, under concrete foot bridge. Fish pass with a small Crump weir constructed winter 1995/1996 - acts as an orifice at high flows. Channel rehabilitation u/s to improve aquatic habitat and maintain low flows.Often out of bank, but the overbank flow passes over the two side weirs. At the highest levels bridge soffit influences upstream level. The weir and fish pass flows are combined (from 2015), and stage and rating only applies to the weir. One peak flow rating applied across period of record. Reasonable fit to available gaugings. Flood Studies Report grade B due to catchment changes (A2 for structure).Site temporarily closed from June 2007 after being vandalised. Not reinstated until 29/09/2009. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8). Catchment underlain by highly permeable Magnesian Limestone, but nearly all the catchment overlain by superficial deposits, mainly Boulder Clay. Dominated by mixed agriculture, considerable urban development d/s in Darlington and Aycliffe. Mixed agricultural land use and significant floodplain drained fen peat (carrs) where overbank flood storage may attenuate extreme flood peaks.Hurworth Burn reservoir (13.4 km2, 6% of catchment) in headwaters, no longer used for water supply. Pumped minewaters can augment flow, but this contribution declines over time. Excess flow from the Cocker Beck is diverted (u/s of Darlington) directly to the Tees. Significant sewage effluent component in low flows.

Station closed 2008 and replaced by 25029.A pre-existing two-stage compound broad-crested weir 17.4m wide, with a bypass Crump profile weir 4.6m wide, adapted for gauging in 1959. The site is badly silted u/s and difficult to maintain. Station closed in May 2008 and replaced by a new station 6km u/s (25029).Sharp bend and road bridge just u/s of weirs. Large drop downstream, therefore believed to be modular throughout range. Tidal effects are rare, water level at weir footings ponded to high tide level since 1995 by Tees Barrage. Some limited bypassing occurs via overspill on u/s bend. Suffered from siltation upstream of the weir which may have affected rating curve. Theoretical rating but lower limb amended to fit check gaugings. Gauged to almost QMED. One peak flow rating applies across period of record.Bypassed once in 2000, but thought to be due to a bridge blockage; 2000 flood peak may consequently be unreliable, though capacity of weir and bridge calculated as 107 cumecs. Suspect daily flow data removed 04/08/2005 - 06/01/2006 during construction of fish pass. Original rating amended based on check gaugings, slight reduction in low flows, high flows unaffected. Rating only applied from 1982, earlier daily flows left unchanged. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Headwaters drain from the Cleveland Hills. Mixed geology of mostly Permian/Jurassic age, generally low permeability. Almost all the catchment is overlain by superficial deposits, mainly Boulder Clay. Mixed agriculture, with some moorland and forestry in headwaters, minor urban development in the lower valley. No known catchment changes. Sensibly natural regime. No known artificial influences.

Constructed at the head of a natural rock fall. No change in control since construction, no permanent cableway although gauged with a temporary winch. Flow is turbulent even when low.Remains modular throughout range. Some bypassing over wing walls, before they were extended, but in extreme cases wrack marks were surveyed in. Ice has been reported in the stilling well in severe winter conditions. Theoretical daily flow rating improved with check gaugings. Previous rating based on structure dimensions and valid up to top of dividing piers. New rating developed in 2010 and modified in March 2013 to improve derivation of low flows, applied from the start of the record. Check gaugings show good fit to rating up to maximum gauging of 1.13m. Flood Studies Report grade B. Extreme flood level in August 1986 exceeded stilling well floor level; peak may be slightly under-estimated as a result. Missing data in February 2008 due to inaccurate drift correction. Flows reprocessed from 1982 onwards in 2002. New rating applied to whole record in March 2013.

Discontinued in 1983 but analogue recorder maintained in operation. Site reopened for peak flows in 2001.Good d/s fall therefore no backwater effects from Harwood Beck and a high modular limit. No by-passing although some flow over left bank floodplain in the August 2004 event, otherwise well-confined. River ice above weir may affect rating in winter. Theoretical peak flow rating to top of wing walls applied across period of record. Rating changed in 2014 to fill a gap at a stage of 0.26-0.3m. Any flows calculated above a stage of 1.5m will be out of bank and flagged as estimated. Good fit to available gaugings up to 0.4m stage but recent higher gaugings suggest rating may under-estimate peak flows and another rating review is required.Peat slip blocked stilling well in summer 1983 thunderstorm, and gravel has blocked previously. New rating applied to period of record in 2014 resulting in a slight increase in flows around a stage of 0.26-0.3m.

Natural regime.Flat-V weir (1:2 crest slopes, 1:10 cross-slope) for low flow control at velocity-area station. Shallow gravel bedded reach, leading to problems with gravel accumulation on weir apron and at the stilling well inlet; most gravel accumulates at the left side, in the past it was removed every 2-3 years but returned with flood flows and continued gravel removal no longer sustainable. Investigations have indicated the gravel is unlikely to affect the discharge characteristics of the weir. Tapping pipe extended in 2007 to avoid blockage. Site difficult to access in bad weather.No bypassing. Doesn't become non-modular. Only gauged at low flows until 2013. Since then ADCP gaugings have been carried out up to 0.935m. Daily flow rating extended using weir equation. Goes out of bank at 1m stage. One peak flow rating applied across period of record. An ADVP was installed in 2008 16m upstream from the primary stage recorder to improve level and flow measurement, but removed in 2012 after it was damaged during high flows. At high flows the rating under estimates flow compared to the check gaugings - probably due to the 'p' value being different to that used in the theoretical rating due to the accumulation of gravel at the site. More gaugings at higher levels are required to confirm this before the rating can be changed.Blocking of the tapping pipe caused elevated low flows from 2002 - 2007: these should be treated with caution. Data for the period of 05/02/2007 to 28/09/2007 is suspect whilst tapping pipe was repaired. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).Small catchment high in the Pennines, underlain mostly by Carboniferous Limestone with extensive peat and Boulder Clay cover.

Station closed 31/12/1996 but re-opened in February 2003 for flood warning. Stokesley (d/s) has been subject to significant flooding from the Leven in the past (the last being in 1976), and historic flood marks, recorded at the police station there, give some support for the high growth rate observed in the AMAX series.Fast approach could occasionally give super-critical flow.

Flow regime influenced by Hurworth Burn reservoir.Velocity area station. Cableway. No wing walls. Straight approach. All flows contained in channel. An informal low-flow control (1:20 cross-slope, 6m wide) was built in 1978 to overcome weed growth problems.Two peak flow ratings applied across period of record, the most recent is valid from September 1978. Rating by fit to current meter gaugings before and after low-flow control. Very well gauged at high flows - up to maximum recorded.Pre-1978 flows influenced by weed growth; weed growth continues to be problematic.Relatively dry catchment mainly on high permeability Magnesian Limestone; almost all the catchment is overlain by superficial deposits, mainly Boulder Clay. Moorland headwaters; mixed agricultural land use and significant floodplain drained fen peak (carrs) where overbank flood storage may attenuate extreme flood peaks. Just over a tenth of the catchment is built-up. No known catchment changes.Hurwroth Burn reservoir covers 13.4km2 of the catchment. In the past, there was a small export of water from two headwater reservoirs (servicing Hartlepool) which used to affect low flows. These reservoirs are no longer in use, but it is unclear when they stopped being used. Minewater additions affect parts of the early record. Up to half of dry-weather flow consists of effluents, mainly sewage.

Cableway. Trapezoidal channel with stone-pitched banks. Prior to March 1973, the invert of a new road bridge 40m d/s of cableway was intended as control; however, silting made the control very unstable. The informal low-flow control (steel sheeting and reinforced concrete cap) was built 1973, with cross-slope of 1:10. Embankments prevent any by-passing although there could be ponding on the flood plain. Approach is affected by heavy growth of weed in summer.Informal structure becomes non-modular at stages greater than 0.4m. High flow control by bridge invert 10m below weir. Weed growth on crest causes up to 10% low flow over-estimation. Multiple peak flow ratings applied across period of record, the most recent is valid from January 1990. Due to a 9 year gap, the gaugings began to show a wide deviation from the previous rating. The current rating (1990-present) does not adequately fit the gaugings due to the variable effect of reed/weed growth, a low non modular limit and a possible change in control. Increased weed management is required at this site and a ADVP may be deployed to try to improve the record.Relatively dry catchment, mostly on highly permeable Magnesian Limestone, but with extensive superficial deposits (mostly Boulder Clay). Mixed agriculture, just over 10% of the catchment is built-up. No known catchment changes.Small net export of water from Hurworth Burn reservoir in headwaters (13.4 sq.km, 19% of catchment - no longer in operation (2015).

Measures full range of flows. Replaced 25005 which closed in 2008. Station added to peak flows dataset in September 2020 (WINFAP Files v9).Station has a purpose-built broad crested weir control, with a free gap to allow fish passage, to retain minimum levels required for ultrasonic gauge. Full range of flows are measured with no bypassing. Small right bank tributary joins just upstream with high sediment load, causes occasional path failures and sediment deposition. Gauged to around 70% of QMED.Some data quality issues result from sediment deposition under the road bridge, thought to arise from the right bank tributary entering just upstream. Gauge error between July 2009 and July 2010 led to some over-estimation of flows during this period by around 15-30%. A power cut at the site resulted in missing data in late June/ early July 2020.Headwaters drain from the Cleveland Hills. Mixed geology of mostly Permian/Jurassic age, generally low permeability. Almost all the catchment is overlain by superficial deposits, mainly Boulder Clay. Mixed agriculture, with some moorland and forestry in headwaters, minor urbanisation in Great Ayton, Stokesley and Hutton Rudby. No known catchment changes.Sensibly natural regime.

Pre-1976, the sluice position was not accurately recorded and the computed flows are less accurate. Eel pass installed September 2012, to be operated only in eel migration season (April-October). Gate lift or drop alters datum, but it is rarely lifted. Weed growth may cause high peaks to be recorded, but station never bypassed. In contrast to much of catchment, station geology is alluvium overlying boulder clay.No known end-contractions or bypassing. Drowning very unlikely due to the weir drop but weed growth can affect u/s levels. Eel pass designed to have minimal impact on the stage-discharge relationship. Single theoretical daily and peak flow rating confirmed by check gauging from bridge used throughout. Flood Studies Report grade A2 assumed due to complicated pen movement.Anomalously high flows in July 2003 thought to be due to temporary damming by landowner. Similar high flow in May 2008 due to dam placed in channel for duck race. March 1999 peak slightly elevated due to lowering of the weir crest, releasing stored water from the ponded reach upstream. Naturalised flows available from the EA from 1995 to 2002. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).A predominantly rural catchment draining the southern Chalk outcrop of the Yorkshire Wolds (but lower catchment is overlain with Boulder Clay with patches of alluvium, sand and gravel). No known catchment changes. Groundwater influences the hydrograph with strong seasonal component, which seldom responds to rainfall. Small groundwater abstractions and sewage treatment discharge, probably affect flows but are insignificant at high flows. The local fishing club used to maintain the upstream level by adjusting the weir plate height.

Ultrasonic gauge in straight channel. Station added to peak flows dataset in October 2018 (WINFAP Files v7).Crossed-path, multi-path ultrasonic gauge in straight section of chalk stream. No stage discharge relationship due to shifting gravels and weed growth, despite weirs downstream and shallow gradient. Weed can be problematic for the gauge and requires regular maintenance to keep the gauge section clear. Gauge generally performs well in comparison with check gaugings. All flows contained, no by-passing.Rural catchment on primarily chalk geology, highly permeable. Upper reaches of the topographical catchment mainly consist of dry valleys, the tributaries of the trout stream generally emerge from springs at the foot of the Yorkshire Wolds. This is the UK's most northerly chalk stream and is designated as a SSSI. Highly baseflow dominated regime, displaying typical seasonal hydrograph with smaller rainfall response super-imposed onto the large baseflow hydrograph.

Theoretically based peak flow rating, checked by current meter gauging (waded), applied throughout period of record.Water levels occasionally subject to sudden fluctuations or spikes, thought to be due to children interfering with the weir and/or the annual duck race in July. These are generally removed during data QA. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).A predominantly rural catchment draining the Yorkshire Wolds. Geology is Chalk with overlying alluvium and gravel in the valley bottoms. The topographical catchment may not match with the groundwater catchment. No known catchment changes.Hydrological response dominated by groundwater. No known artificial influences.

Station intended to be replaced by full-range ultrasonic gauge at Skip Bridge (27062) but remains open. Low flows monitored d/s at Skip Bridge since 1979 - 12 cumecs is a sensible split between the two records.Insensitive weir due to width. Weir by-passed at highest levels, beginning at 2.41m, and drowns. Cableway 1km downstream at Cowthorpe, also by-passed and drowned in extreme flows. Multiple peak flow ratings apply across period of record, different lower limbs have been used for periods when opening of by-pass sluice gate affected flows. Flood Studies Report grade A2.Flows in pre-digital period cannot be reprocessed and therefore peak flows are marked as rejected. Operation of by-pass sluice in the 1980s caused difficulties; flows subsequently revised. No data for June 1984 - March 1985 due to site works. 2015 peak is believed to be the rank 1 event, flows from 1966 onwards have all been re-processed with revised ratings, earlier peaks (notably 1946, 1965) still rely on old ratings and likely to be overestimated. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Mostly moderately permeable. Upper Carboniferous Millstone Grit series down to Knaresborough, where Carboniferous Goredale rocks form an inlier. Magnesian Limestone lies on top of the Grits, dipping east, followed by general drift cover below Knaresborough. Just under half of the catchment is overlain by superficial deposits. Predominantly rural; half grassland with moorland headwaters and arable in lower valley which is flat and the river meandering. No known catchment changes.Opening and closing of mill race sluices has occurred but was unlikely to have affected high flows. Regulatory effect of headwater reservoirs (Angram, Scar House and Gouthwaite) is evident at low flows. Gouthwaite controls 24% of the catchment and has a significant impact in drought periods. Mill operation evident in the early record. Overall net export of water.

Tadcaster ultrasonic gauge (27089) installed 1990, intended to replace Flint Mill but station retained primarily for high flow measurement. Check gauged at cableway 1.5km u/s but this was moved to 27089 in 1990. Flow was originally recorded on a flow chart up to the level of weir by-passing (1.6m), and level thereafter. Mill sluice operation in 1990s and modification of weir in 2010 affect low flow measurements.Weir control insensitive at low flows. Unlikely to drown at high flows, though small amount of bypassing on the right bank possible. One peak flow rating applied across period of record, originally derived by weir formula then checked by current meter with good fit to gaugings. FSR rated excellent for high flows. Weir repairs in 2010 have altered the crest level, rating review is ongoing (2019).For early records, chart zero was often set 0.3m below the weir crest to allow for the weir crest drying up due to leakage. This practice stopped in the 1960s. Flow charts from 1936-1955 considered unreliable and have not been digitised. Flow charts from 1955 to 1965 are digitised but have not been reprocessed with revised rating. Records since 1965 have been reprocessed with revised rating and are considered reliable for high flows, pre-1965 data is less reliable. Gap in data in 2010 due to weir repairs carried out by the landowner. No mean flows held since 2010 due to ongoing issues and pending rating review. Peaks flows are unaffected and held post-2010. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Mixed geology of moderate permeability - mainly Carboniferous Limestone, grits and Coal Measures with just under half the catchment overlain by superficial deposits. Predominantly mixed rural catchment, two thirds of the catchment is grassland, with moorland headwaters. No known catchment changes.Regulation effect of headwater reservoirs evident at low flows. Small net export of water to the Aire Valley (including Bradford supply).

The heavily reservoired catchment drains a large part of the East Pennines.Broad-crested masonry weir (33.5m wide) with an additional 9.1m of sluices on the right bank, acts as the control at this site. A long established station, 7 km upstream of the tidal limit of the Aire (Haddlesey Weir). The original gauge was on the weir, with a cableway 4.5km u/s (led to limited low flow accuracy); improved performance using new site for cableway and instruments (500m u/s of weir) from June 1993. Flow records combined. Non-standard weir control rated by gaugings. Bypassing over the left bank begins at around 3.8m stage (at new station) and occurs on a roughly annual basis. At around QMED, flows inundate extensive N bank washlands. By-passing via the Aire and Calder navigation at Ferrybridge (measured at Whitley Lock); thus sum of upstream tributary flow volume at Lemonroyd (27080) and Methley (27079) is 5-12% greater than flow at Beal. Four peak flow ratings applied across period of record, two at old Beal and two at new Beal, latest revision was in 2016. Numerous problems resulting in Flood Studies Report grade Z in 1975, now graded A1, although the site still suffers regular overtopping into washlands on its left bank.Neither the recorder nor cableway was able to measure the full range of flows until after the 1940s. Early peaks flattened by limited pen-range and original theoretical formula was not held to be accurate due to use of timber 'deals' and drowning of the weir at around 1m head. Flood peaks are still truncated due to spill into washlands limiting the peak level reached at the gauge. Q95 has decreased significantly in the recent past, which is thought to be due to increasing abstractions for canal. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8). Catchment drains a large tract of the East side of the Pennines, including the catchments of the rivers Colne, Calder and Aire. The geology is mixed with Carboniferous Limestone in the upper Aire, Millstone Grit and Coal Measures in the Calder and mid-Aire, Magnesian Limestone, Marl and Triassic Sandstone in the lower catchment. Some superficial deposits. Mixed land use, with extensive around a fifth of the catchment is urbanised areas. The headwaters are predominantly rural moorland and are used for rough grazing. Areas of heavy urbanisation and significant industry in the mid catchment which includes the Leeds-Bradford conurbation. Agriculture, including significant arable, continues in the lower reaches. 11.6% of the total catchment drains through around 50 reservoirs, the larger of which include Butterley (Colne), Ryburn, Boothwood (Calder), Winterburn, Ponden and Hewenden (Aire). Considerable increases in urban development and industry during the period of record. Ongoing decline of the coal mining industry around Knottingley and Pontefract.Heavily reservoired including the following groups - Aire (controlling 4.6% of total area), Calder (4.6%), Colne (2.1%). A complex water utilisation network exists, with net imports from the rivers Nidd, Wharfe, Ure and Derwent returned to the Aire upstream of the gauge vie sewage treatment works discharges. Large abstraction made to the Goole and Knottingley Canal upstream of the station. Heavily industrialised with abstractions made to Ferrybridge power station.

Replaced Kirkthorpe Weir in 1968. Station closed in 1977 and replaced by 27079 (Methley) in 1988.Velocity area station, an adjacent thin-plate weir measured diversions to canal, built in 1956 and levels recorded from 1957. Newlands is situated in an open channel 26m wide, without formal control, at Newland Hall railway-bridge, 4.8km d/s of Wakefield and 1.5km d/s of Kirkthorpe Weir. In October 1968, Newlands replaced the original station at Kirkthorpe Weir (built 1827) to maintain levels in the Aire and Calder Navigation (records from 1960 with some earlier data back to 1927). Newlands closed in 1977 and replaced by 27079 (Methley, flows from 1988), although current meter gauging using the cableway was continued at Newlands. Multiple peak flow ratings applied across period of record, the most recent is valid from October 1969 when pressure transducer installed. Rated by multipoint current metering using cableway prior to 1969.Mixed permeability geology of Carboniferous Sediments; Millstone Grit in the upper catchment, dipping east under Lower and Middle Coal Measures and overlain by alluvium and sand. It is not tidally influenced. Upland headwaters. Rural land use predominates with moorland in headwaters. Newlands is located near the downstream limit of a highly industrialised catchment. There are numerous large population centres within the catchment including Huddersfield, Halifax and Wakefield. From 1957, abstraction and discharge for cooling at Wakefield generating station. Continued intensive coal mining including underneath river has resulted in subsidence. Continued erosion of upstream riverbanks has prompted remediation by stoning by Navigation authorities. There have also been significant changes to channel morphology, with banks being raised or lowered.The catchment is heavily reservoired, with 5.9% draining through an impoundment. Water abstractions returned to river as sewage effluent u/s of gauge. Import of water from Dewsbury and Heckmondwike and from Wharfe and Nidd. Continued abstraction to Navigation canal which was temporarily gauged at Birchwood Lock, 3km downstream of the intake.

Heavily reservoired catchment draining the East Pennines.Broad-crested, skewed, semi-circular masonry weir (44.5m wide) with sloping upstream face. Upstream level recorder since 1921 originally poor due to limited range and position at foundry intake, now located on inside bend in river, upstream of the weir. Cableway installed 1961 located 100m d/s destroyed in 1989, new cableway installed u/s in November 1997. Hut and contents stolen, 1985, replaced 1986. Fish pass installed November 2012.Rarely bypassed or drowned. Current meter gauging previously from footbridge, downstream of weir. Rated by a current meter from a cableway. Revised rating applied in December 2014 back to November 2012 following fish pass construction. This rating alters the lower limb (below 0.52m stage) to compensate for the fish pass. Four peak flow ratings applied across period of record. Good fit to gaugings. In 1975 Flood Studies Report grade A2 to 2m and B above (overall grade A2). Current grade A1 to 2m and A2 above.Data is available from 21/11/1956. Flows from 1982 reprocessed in 2002 and 2014. Bypassed in June 2007 event. June 2007 peak flow is estimated 259 cumecs and stage 4.68m (wrack survey). Flows reprocessed from 2/11/2012 in 2015 after new rating developed for fish pass resulting in a slightly lower flow estimate. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Catchment draining the eastern flank of the Pennines, to Sheffield. Mixed geology including Upper Carboniferous Millstone Grit, Middle and Lower Coal Measures sandstones and shales with a generally easterly dip. Moorland headwaters used for rough grazing contrast with the heavily urbanised (up to a fifth of the catchment) lower catchment (now less industrial); mixed rural in mid-catchment. Ongoing increase in area of development during period of record.Fast responding catchment with a large urban component near to the outlet. Heavily reservoired with estimated 40% of catchment draining through around 23 reservoirs. Variation in Don Valley reservoir content has very significant effect on overall percentage runoff from the catchment in flood. Addition of water from borehole to Scout Dyke reservoir group, intermittent discharge from South Yorkshire Navigation and sewage treatment effluent discharge. Compensation forms a large part of baseflow. Significant net loss of water from the catchment with abstraction to Yorkshire Grid.

This replaced an earlier rated section d/s of the weir near the canal lock, Boroughbridge weir was thought to act as partial control fore the old station. Location was moved u/s of the (existing) weir in November 1975, initially on the right bank, then moved to current location on left bank in 2010. The weir is now in poor repair. Hydropower scheme installed November 2011 and includes a bypass channel, gauged separately.Some out-of-bank flooding at very high flows - peaks may be underestimated. Pre- 2009, the cableway was inaccessible at very high flows, accessibility improved when moved to the left bank; however, there is still some minor bypassing behind the right bank stantion in very high flood events. Three peak flow ratings have been applied for different periods, daily mean flow ratings are not always the same as for peak flows. Peak rating periods are: d/s gauge 1955-Aug1970 and Aug1970-Nov1975, the gauge u/s of weir (Nov1975-present). The latter was supplemented in 1998 by Hydraulics Research analysis, with a more accurate relationship for stages above 2m. Hydropower bypass channel affects low flow measurement and is gauged separately to the main channel (Acoustic Doppler gauge with velocity-index rating), flows from the main and bypass channel are added together to give a total flow. Gaugings at cableway measure total flow and therefore may not fit well to rating when Hydropower scheme is operating, they should be compared with total flow series.Flows prior to November 1975 have lower confidence due to various changes in rating and changes to condition of Boroughbridge weir (control for early records. Flows are rejected pre-1970 because the earliest rating and data cannot be confirmed. Increased confidence to post November 1975 data after recorder moved to upstream of weir, however still some uncertainty in highest flows due to by-passing of the cableway. This improved after the cableway was moved to the left bank in 2009/10. From November 2011 onwards flows are derived from the rating curve plus addition of measured flow in the hydropower intake channel. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).Mixed geology of limestone and grits, with significant Boulder Clay cover. The Millstone is hilly, but further downstream the Limestone and Marl form a flat plain. Upstream of Kilgram Bridge the rocks are mainly Carboniferous Limestone and the catchment is steep. Predominantly mixed agriculture catchment draining from moorland headwaters in the Pennines. No known catchment changes.Reservoirs have a significant effect on the Burn and Laver, but have a moderate overall impact; some net export of water. 'Grip' drainage also influential.

Station closed December 1984.Velocity area station, channel 22m wide at low flows, 180m d/s of the Swale/Cod beck confluence. No single effective control - heavy summer weed growth. Station superseded by Crakehill (27071) in 1980 1.5km d/s (but cableway still used for high flow calibration). Station closed 31-12-1984.Stage-discharge relationship is affected by heavy weed growth at low flows; bypassing begins at 6.15m over left bank at high flows. Peak flow rating changed in October 1968 to account for downstream bank erosion. High flows are suspected to be largely over-estimated by the rating.Peak flow record from this station is combined with records from 27071 (Crakehill) from 1980 to give extended flow record. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Geology comprises mainly Limestones, Triassic Sandstones and Shales with over half the catchment overlain by Boulder Clay. Predominantly mixed agriculture with moorland headwaters draining the North Yorkshire Dales. No known catchment changes.No known artificial influences.

Previously velocity-area station. Catchment drains northern parts of the Vale of York and the Yorkshire Dales.Multi-path (cross-configuration) ultrasonic station u/s from 1992. It was previously a velocity-area station since 1956 (37m wide at low flows), with control exercised mainly by Naburn weir, 13km d/s. A difficult site for flood estimation due to lack of similar catchments yet is not entirely suitable for single-site analysis.High flows overtop the left bank u/s, but return through the section. For flood events above 9m AOD (4.46m stage) there is some unmeasured flow behind the highest transducer path. This was estimated as 23 cumecs (4%) in the AMAX1 event (November 2000), it will be less for lower order floods. Daily flow rating change followed construction of the Clifton Ings embankments (c1980). For 1982-1992 a rating independent of Naburn sluice-gate settings has been employed. Multiple peak flow ratings applied over period of record. Ultrasonic since 1992 with ratings used to infill missing data, good measurement of high flows. Flood Studies Report grade A2. Pre-1982 records are less reliable, especially at low flows, but above 2m the effect is probably not severe. Due to rating review AMAX series re-calculated (to 2001 water year). Bed level was programmed incorrectly for a period, leading to approx 26 cumecs being missed in November 2000 event. The peak has been corrected for these errors.Mixed geology, mostly of moderate permeability but highly permeable in lower reaches; extensive superficial deposits mask solid geology in much of catchment, particularly Vale of York. Large areas of Carboniferous Limestone and Millstone Grit in the west, Permian Magnesian Limestone in the central area and Keuper Marl and Triassic Sandsone to the east. Along the eastern border are rocks of the Lias and Great and Inferior Oolite Series. Predominantly rural catchment draining north parts of Vale of York and Yorkshire Dales, with some moorland headwaters. No known catchment changes.Public water supply abstraction u/s at Niddmouth, with increasing impact on very low flows. Some artificial groundwater augmentation is now a counterbalancing influence.

Heavily urbanised catchment and numerous artificial influences on the flow regime. Full range ultrasonic since 2000 in the centre of Doncaster. Previously a velocity-area station, 24m wide, formerly with cableway in a straight, embanked open channel reach from 1958. The ultrasonics are in an open channel control with significant hysteresis. New road bridge completed January 2001. Stage Discharge rating still preferred for peak flows.By-passing via the Sheffield and South Yorkshire Navigation, 1km u/s and is measured at Long Sandall Lock. Significant scatter in gaugings above 1m stage. Recalibrated in late 1970s following removal of rubble weir (low flow control) due to measurement problems. Gauge zero was raised 1m in April 1978. Daily mean flow rating reviewed in 2014: Rating D implemented 11/01/1978-31/12/2000, Rating E implemented 01/01/2001 to present. Rated by check gauging (by cableway 1977 to 2000). Extrapolated above 5.49m. Full range Ultrasonic available since December 2000. Flood Studies Report (1975) grade A1 to 2.3m, B above this. Intermittent records exist for as early as 1868 (see FSR), but they are not considered reliable, or representative of the modern catchment. Channel improvements, carried out in 1957, lowered water levels in the lower Don. Missing data 1976-1977 due to rubble weir removal. Post-1977 flows reprocessed in 2014. November 2000 flood peak is believed to be underestimated. June 2007 flood peak gauged at c.350 cumecs by ADVP. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).The catchment drains the east flank of the Pennines above Chesterfield, Sheffield and Barnsley. Mixed geology: Millstone Grit (headwaters), Coal Measures, Magnesian Limestone and Triassic Sandstones. Moorland headwaters, mixed agriculture in valleys along with significant industrialisation and urbanisation, including Sheffield, Rotherham and Doncaster. The eastern part of the catchment is low-lying, and was historically marshland, being drained in the 17th and 18th centuries by Dutch engineers. Historic tree-clearing, particularly in the Rother and Dearne valleys. Old mining areas are commonly subject to subsequent land-subsidence which poses a problem for the extensive raised flood banks. Once agricultural, Doncaster and Askern are now largely urbanised. Recent landscaping of Rother Country Park included significant tree planting. River regulators have been introduced over a period of time from 1958 to 1988.River regulators and sluices on the Rother and Dearne tributaries control the operation of washlands in large floods. The heavily reservoired Don headwaters and Chesterfield and Clowne areas provide for a net import for supply via supply from the Derwent Valley and groundwater abstractions.

Heavily influenced by headwater reservoirs. Station closed in December 1971. Reopened in 2005, initially as a level only station but subsequently re-rated and flows calculated again from 8/11/2005.A large masonry weir 61m wide calibrated at a velocity area station 360m d/s. The weir is at an angle to the upstream channel. Recorders u/s and d/s of the weir (the d/s gauge was removed in 1966). Chart records from u/s recorder since 1924. New recorder installed in 1958 and flow calculated from October 1960. Station closed in 1971. The station was reinstated in 2005 as a level only station when a level recorder and an H-ADVP in a 24m wide channel ~80m upstream of the weir were installed. The H-ADVP gauge has since been removed but a new rating was established and used to calculate flows again from November 2005.Good measuring reach enclosed by steep riverbanks and weir not thought to drown. One peak flow rating applied across original period of record (1960-1970). Rating derived from multipoint current meter gaugings from cableway. Flood Studies Report grade A2 at all flows. New rating developed following re-opening of gauge and applied to period from 11/2005 to date. Gauged up to bankfull stage and rating gives a good fit to gaugings.Record thought to be of little use before 1961. Records pre-1947 now thought lost. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Mixed geology: Millstone Grit (headwaters), Coal Measures, Magnesian Limestone and Triassic Sandstones. Moorland headwaters, mixed agriculture in valleys with significant urban areas, including Sheffield. Headwaters are heavily reservoired. Decline of coal mining and manufacturing industries throughout the period of record. Extensive urban development around Sheffield (with several large green field developments during the 1970s) and Chesterfield during period of record.Headwaters are heavily reservoired with around two thirds of the catchment draining through some 27 impoundments and valleys are highly developed. The Rother has significant washlands (although few were controlled by 1971). Traditional industries including steel and mining are now in decline. Sewage effluent augmentation with approximately 2/3 of abstraction to public water supply returned to Rother above gauge. Import from Derwent Valley, but overall net loss of water from Don to Dearne. Abstraction into the Sheffield and South Yorkshire Navigation canal just upstream of the gauge.

Rarely bypasses over the right bank. Two peak flow ratings applied across period of record. Theoretical rating for daily and peak flows originally developed using physical model with current meter gaugings. Rating revised in 2016. Gauged to a very high level in June 2007 but measured peak 0.75m above this gauging. Flood Studies Report grade A2 in absence of any other information, 1975 now A1 to 1.3m and grade B above.Daily gauge readings commenced in June 1953, continuous flow records from March 1960. Extreme flood event in June 2007 well above any previous known floods. Period between 1953 and 1959 rejected due to unknown provenance of data. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).Mixed geology of Upper Carboniferous, coal measures, very little superficial deposits. Predominantly rural catchment, mixed agriculture and woodland with urban development near gauging station. No trace of original course of River Dearne.Some abstractions, including industrial uses. Discharge of minewater drainage - decreasing influence.

Catchment includes former opencast mine Rother Valley Country Park.Velocity area station (15m wide) in trapezoidal channel with current meter cableway. Gauge is downstream of a washland storage scheme and catchment has been significantly impacted by opencast mining.Large trapezoidal channel with partial control from Orgreave weir 1.2 km downstream. No by-passing but flow is affected by upstream regulator and washland storage scheme, operation of the regulator holds water back during large flood events. Some variability in the rating at low flows, possibly due to seasonal weedgrowth. Channel also affected by modifications from opencast mine remediation and subsidence. Some evidence for lag/drawdown in stilling well in large flood events. Rated by gaugings, two ratings applied across period of record, latest applies from January 1974, although Orgreave weir was breached in June 1973 and repairs not completed until October 1974. Rating based on multipoint current meter gaugings and more recently with ADCP measurements. Flood Studies Report grade B assumed in 1975, now A1 to 2m, A2 to 3m and B above.Chart records from May 1959 and flow records from October 1961. Sequences of identical low flows in the 1960s (but realistic). Control breached June 1973, repaired October 1974 but PTR found to be faulty and daily flow records not considered reliable until January 1976. Records from 01/1974 reprocessed (1977), earlier records are less reliable. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).Catchment draining the moors and fertile farming valleys southwest of Sheffield. Mixed geology, principally Middle and Lower Coal Measures, with overlying Permian sands, marls and Magnesian Limestone are found down the eastern watershed. Land use: moorland headwaters, mixed farming and heavily urbanised valleys. Extensive urban development of Chesterfield over period of record.Rother Valley Country Park mined by opencast methods, 1976-1981 but restored to become large controlled washlands in 1988. The washlands upstream of Woodhouse Mill are controlled by two in-line river regulators, which results in occasional distortion of the natural hydrograph. These structures have been operated several times during floods (including 2000, 2007, 2012 and 2019) and have a very significant effect on peak flows in the Rother. Abstractions and storage in reservoirs of northeast Derbyshire, Chesterfield, Bolsover and Clowne. Imports from the Derwent Valley reservoirs to Linacre reservoir. Abstractions to water supply from Ogston reservoir. Borehole abstractions made to Crowhole reservoir.

Flow regime influenced by numerous abstractions and diversions.Flat-V weir in an open-channel, on a straight, stable reach, just downstream of Chesterfield. Cableway located 50m u/s rebuilt 2003; new cableway covers larger cross-section of river. Replaced a shallow masonry V weir located a short distance upstream in October 1979. Improvements in water quality may be responsible for heavy, summer weed-growth.Flows greater than the capacity of the weir rated using cableway 50m u/s. Railway embankment and high river wall at sewage treatment works thought to fully contain high flows, but hydraulic modelling suggests peak flows (>60 cumecs) may be underestimated. Flows bypassing station via Chesterfield Canal were measured at Wheeldon Mill Lock from October 1963 to 1989. Two peak flow ratings applied across period of record. Rating reviewed in 2012 and modified to increase flows slightly above bankfull stage, based on gauging during 2007 flood event - applied back to November 1979 when previous masonry weir replaced with current structure. Flood Studies Report grade A1 in 1975, now graded A1 to 2.9m and B above.Flows from November 1979 reprocessed in 1996 and 2012. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).A catchment draining moors and fertile farming valleys to the southwest of Sheffield, including Dronfield and Chesterfield. Comprising mostly Pennine uplandsGeology: mainly Coal Measures with underlying Millstone Grit outcropping in the southwest of the catchment, except for a narrow alluvial strip, down the axis of a geosyncline in the valley. Mixed agriculture predominates, some moorland in headwaters (Peak District). Substantial urban development - population has grown fourfold since 1945. Industry has developed alongside residential growth. Once commonplace, now few traces of coal mining in the area remain. Chesterfield is immediately u/s of station.Flows from November 1979 reprocessed in 1996 and 2012. The pre-1979 rating is a poor fit to gaugings and flows are likely to be underestimated.

Net inflow to the catchment from springs and sink holes. Station closed December 1975.Velocity area station 20m u/s of Ilkley Old Bridge, the paved invert of which is low flow control for station. Open channel 37m wide. Replaced by Addingham (27043) 3.3km upstream in 1973. Discontinued as flow station in 1975 but level record continues. Cableway still used for calibration of Addingham.Bypassing begins at 3.6m over the left flood bank and flows on the flood plain. Minor draw-down problem in float well. Multiple peak flow ratings applied across period of record, the most recent is valid from January 1970. Rated by current meter gauging from bridge and correlation with Addingham record, adjusted for abstractions and greater catchment area. Flood Studies Report grade A1.Predominantly Lower Carboniferous Limestone and shales in the upper two-thirds of the catchment, and Upper Carboniferous grits and sandstones in the lower parts near Addingham. Extensive Boulder Clay and alluvium. No known catchment changes. There are many springs and sink holes, and an examination of the catchment losses suggests there may be net inflow to the catchment. Water supply reservoirs at Barden and Chelker result in net export of water from the catchment, returns are through the Aire and Calder system. Grimwith reservoir upstream (catchment area about 25 sq.km) provided compensation releases to augment low flows.

Lower catchment is heavily urbanised. The headwaters are rural and influenced by numerous reservoirs.Velocity area station on a straight, industrial reach. Station is located 100m downstream of twin arch viaduct, and confined by canal embankment (right bank, 11.19m) and a high wall (left bank, 5.96m). Channel control provided by two broad-crested weirs set in arches (20m wide) 1.8km d/s under Leeds train station. Station prone to heavy weedgrowth in summer. Changes in weir condition, 1971 and crest deterioration, 1975 not thought important for high flows. Weir crest reconstructed 1978. Instrument building destroyed by fire in 2008, station rebuilt at same section but on opposite (left) bank in 2010.Rated for all flows by cableway at the section. No bypassing is known but wall was close to overtopping in 2000. Weir crest reconstructed and re-rated in April 1978, but flood calibration was unaltered. Two peak flow ratings applied across period of record. Upper limb of all ratings since April 1978. Low flow weed correction not shown. Pre-1971 data are less reliable. Data 19/05/2008 to 08/09/2010 estimated using correlation with Leeds City Station gauge a short distance downstream due to temporary station closure. Estimates are within +/-15% of expected Armley flows. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Catchment draining the east side of the Pennines above Leeds. Geology comprises predominantly Carboniferous Limestone in the headwaters down to Skipton, and Millstone Grit and Lower Coal Measures. Extensive superficial deposits. Rural headwaters, with considerable urban and industrial development in the lower catchment. Influenced by reservoirs. Estimated 12.7% of catchment drains through 18 impoundments. Large reservoirs include Winterburn, Ponden, the Denholme Group.Reservoir groups include Skipton, controlling 4.1% of total area, Keighley 4.7%, Denholme 1.8% and Bingley 1.8%. Zero flow when river level drawn down below weir crest by Kirkstall Power Station (license revoked 1978), now closed. Abstractions returned to river on site. Discharge received from sewage treatment at Bradford (Esholt) and some industrial abstractions. Washlands created at Skipton and Silsden to manage flooding at Keighley and Leeds.

In July 1969, deteriorating timber-crest replaced by concrete-cap. Low flow notch enlarged 1971 followed by recalibration. The weir is a short distance downstream of a bend. When the old canal, 'Tag Cut' was infilled, historic problem of flows bypassing the station removed.Current metering of low-flows was originally from the footbridge 200m downstream in June 1954, then from 1962 using an adjacent cableway. A pressure-bulb recorder was installed to monitor high flows in 1969. Cableway burned 1989 replaced by rail on vehicle bridge 200m d/s, 1996. Water level recorder re-sited nearer the river in 1980. Flow out of bank at recorder is contained at cableway. Two peak flow ratings applied across the period of record. Crump weir formula for weir notch with main weir calibrated by current metering from bridge. Flood Studies Report grade of A2 downgraded to C when computed flows were compared with original rating in 1975.Previous period-of-record maximum flow occurred in October 1967 but considerable uncertainty surrounds the event magnitude. The EA record a figure of 520 cumecs, but this is known to have been extrapolated and may have been affected by hydrometric changes. Weir breached and repaired to same specifications in June 1982 necessitating a new rating curve. Flows reprocessed, resulting in a substantial increase in high flows and a decrease in low flows. Gaugings from 1987 were subject to systematic error and not used. Rating review in 2020, based on hydraulic modelling, reduced flows above 1.65m stage (1971-present). Pre-1971 peak flows are rejected as there is no known suitable rating for this period.Catchment draining the eastern flank of the Pennines, above Halifax. Geology comprises Upper Carboniferous Millstone Grit Series but includes a small area of Lower Coal Measures at Elland. The headwaters rise from peat-covered moorland. Very steep and often-wooded, headwater valleys cut down through Millstone Grit. Valley bottoms of lower catchment are heavily urbanised and industrialised. Valleys rise steeply to moorland predominantly covered by peat. Higher land is roughly grazed. The valley floors are urbanised and industrialised; the catchment contains Halifax and Elland. Increasing urbanisation in valley bottom towns during period of record.Heavily impounded with around 18 reservoirs controlling about 15.4% of total watershed, mainly by small impoundments, but including Walshaw Dean. Some abstraction to supply the Yorkshire Grid.

Flow regime controlled by washlands since the gradual closure of mines. Compound Crump weir with broad-crested flanks built 1963, total width 17.4m, 400m d/s of Adwick Bridge. Cableway located 25m upstream of weir. Fish pass installed June 2013.Compound weir with central Crump profile section 5.5m wide, broad-crested flanking weirs with crests 0.4m higher than central weir, sloping side walls and no divide piers. No known bypassing, flow contained by raised embankments, however site is subject to variable back-water from the river Don confluence downstream in large flood events. Problems with draw down effect in stilling well were remedied in 1968. Weir possibly subject to mining subsidence. Rating developed from Crump formula modified to fit to check gaugings at cableway 25m upstream. Rating revised in 2016 to account for drowning / variable backwater but considerable scatter in gaugings above 1.2m stage. Separate level record and rating for fish pass (installed 2013) with flow added to weir flow to calculate total flow. Flood Studies Report grade A2 to 1.4m then B for straight-line extrapolation.Continuous level data from 1961. Flow data from November 1963 but data pre-1975 is thought to be less reliable. Post-1975 flows reprocessed in 1996 (low flows reduced, high flows increased) and again in 2016 (high flows reduced). Major flood events affected by backwater, allowed for in rating but with considerable uncertainty above 1.2m stage (40 cumecs). Increased flows 02/12/2013-05/12/2013 a result on contractors working on site affecting the water level. Data marked as estimated. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).Geology: primarily Carboniferous Coal Measures. Lower Coal Measures dip gently east northeast under more extensive Middle Coal Measures. Shales, overlain by alluvium. Land use: arable farming and moorland pasture in the headwaters. Significant urban development in middle reaches and valleys, including Barnsely. Coal mining and subsequent subsidence of land. Decline of coal mining and manufacturing industries throughout the period of record. Barnsley's growing population (and thereby development) peaked with the mining economy in 1971 (a quarter of Barnsley's population of Barnsley worked in mining by 1981). All mines were closed by 1994 with population decline since. The death of the industry left a legacy of abandoned deep mining pits and opencast coalmines, their associated spoil tips and mine works.Abstraction to supply from Scout Dike reservoir group and Midhope reservoirs in the Don, discharged to Dearne. Reservoir influence from Worsborough and Bretton Lakes draining around 20% of the catchment. Moderately heavy industrialisation, mine drainage, sewage effluent augmentation and net import of water from Don. Hydrological characteristics altered by surface works and groundwater rebound in response to mine water pumping. The construction of washlands in the Dearne catchment has been an ongoing activity since the gradual closure of mines. Some of the washlands are controlled by two structures: A river regulator at Bolton (upstream of Adwick) and a side sluice gate at Dearne Mouth (downstream). Uncontrolled washlands operate at flows from QMED upwards, the sluice and regulator are operated only in major flood events.

There are some problems of silting.Weir control, no bypassing. Low flow rating from Crump formula, empirical rating for higher flows fitted to gaugings at cableway 200m d/s. Gauged to AMAX3 and 85% of AMAX1. Rating reviewed in 2020, revised rating D gives good fit to high flow gaugings from 2012 flood event. Flood Studies Report grade B.Although such events are rare, the 1946 flood level reached 2.4m over the Crump. Low flows in February 1992 due to a landslip event causing ponding u/s of station; flows bypassed through nearby canal. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).The catchment draining the East side of the Pennines above Huddersfield. Mixed geology with Carboniferous Millstone Grit in the upper catchment and Coal Measures, which dip under Lower Coal Measures in the lower part. Catchment comprises peat-covered moorland headwaters used for rough grazing. Steep valleys descend rapidly to heavily industrialised and densely settled valley bottoms and which includes Huddersfield. Continuing increase in urbanisation around Huddersfield during period of record.There are numerous small storage reservoirs in the Colne valley. An estimated 16.75% of catchment drains through around 8 reservoirs. Abstractions are made for supply at Huddersfield. Some imports of water received from Deanhead reservoir and groundwater abstractions. Export of water is made from Blackmoorfoot reservoir. Industrial abstraction from downstream of the confluence with the Calder is discharged back to the Colne upstream of the station. Industrial abstraction along the Huddersfield Broad Canal.

Partially Karstic catchment, true drainage area unknown.Thin-plate V notch (half 90 degree) in parallel with 3.35m wide Crump profile weir. V notch capacity limited by horizontal cut-off wall, at high flows it acts as a submerged orifice. V notch was installed for its great sensitivity at low flows, as Craven Water Board were not permitted to abstract when flow fell below 0.01 cumecs. Steep stream with heavy bedload - substantial u/s accretion, some erosion evident on weir surfaces.No bypassing, but wing walls may be overtopped. One peak flow rating applied across period of record derived from V-notch and Crump weir formulae and confirmed by current meter gaugings. Rating agrees well with gaugings at high flows. Flood Studies Report grade A1.Considered to provide reasonable data. Largest recorded event (October 1998) may have been due to an u/s blockage and subsequent 'dam break'. Suspect flat trace in May-June 2004 due to instrumentation problems. Peak flow on 20/06/2014 thought to be correct, 15.6mm of rain recorded at Grimwith tipping bucket raingauge. Steep, upland catchment; mostly moorland developed on Carboniferous Limestone, Millstone Grit and Shales. The watercourse flows in a boulder channel. The catchment is partly Karstic Limestone and has numerous swallow holes and resurgences; true drainage area uncertain. No known catchment changes.Some abstraction (27032 monitors residual flow), but predominantly natural flow regime. Exhibits unresponsive behaviour during some periods of lower flow (e.g., 1999, 2000), probably due to sinkholes in catchment. Flow regime influenced by old mine workings. The Karstic portion of the catchment only contributes runoff in exceptional floods.

This means the contributing area varies at high flows. Compound broad-crested weir 21m wide with central notch 2.9m wide and crest level of 20.6 mAOD; the flanking weirs are 0.152m higher. A cascade of weirs, making drowning highly unlikely. The channel was artificially extended in the last century. The Sea Cut is primarily a diversion channel which passes flood waters from the upper 88.8 sq.km of the Derwent, although it has a small catchment of its own as well.Many springs d/s of the gauge hinder estimation of flow without the Derwent contribution. A sluice allows a maximum of 5 cumecs to flow into the Derwent when fully open, but can be overtopped. Daily flows rated by model tests. One peak flow rating applied across period of record. Good fit to available gaugings at lower flows but recent high flow gaugings suggest rating under-estimates high flows and a rating review is required. The catchment is unsuitable for pooling for flood estimation. Flood Studies Report assumed grade to be A2.Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).The natural catchment drains part of the North York Moors. Contributing area varies by +/- 88.8 sq.km because of the artificial connection to the headwaters of the Derwent. Geology of natural catchment is Oolite Cornbrash, Oxford Clays and Corallian of the Jurassic Period, which dip south and are overlain in the east by thick Boulder Clay deposits. No known catchment changes.Sea Cut flows are controlled by a sluice; the channel was artificially extended in the 19th century to join the Derwent, and now acts as an overflow channel in high flows.

Flow is through between one (10m wide) and four (40m wide) of the arches depending on level. Flow begins to surcharge the arches at different levels. The bridge sills provide the low flow control; soffits control high flows. The road bridge and steep grassy banks prevent bypassing, all but the highest discharges are contained. Flood Studies Report was graded Z in 1975. Two peak flow ratings applied across period of record, the most recent is valid from July 1971. Increasing scatter in gaugings beyond 1m but is stable up to 1.8m.Geology: mainly Carboniferous Limestone with some Millstone Grit series, with extensive Boulder Clay cover. Rural catchment, over three-quarters grassland, draining the eastern Pennines. The catchment headwaters are undeveloped with moorland. Land use consists of upland rough grazing, and pasture and light urbanisation in the valley bottoms (Skipton is the largest town). No known significant catchment changes.Between Skipton and Kildwick, there are considerable areas of washlands, which fill during floods. Abstraction for supply is made from reservoirs at Winterburn, Embsay and Elslack. The Leeds-Liverpool Canal can influence the flow pattern but has a small overall impact. There is a small net export from the catchment.

Weed growth can be problematic at the station.Single-crest Crump profile weir 5.2m wide, between the abutments of a demolished railway bridge, in a largely artificial section which has been canalised for drainage. The bed is silty and accretion occurs on the weir apron. Removed from peak flows dataset in April 2017 (WINFAP Files v5).Some bypassing of gauge via West Drain, but all flows at the station are contained within the high wing walls. Weed growth can cause drowning at low flows, as can water backing up from the Vale of Pickering. Modular limit estimated at 0.45m, gauged up to 0.21m. Theoretically rated for daily flows using Crump formula, but this is inaccurate at high flows. Rating applies from record start.Long periods of extensive weed growth can make measured stage and applied rating inapplicable. Station affected by weed growth causing missing data and suspect flows (e.g. 2000, 2001 & 2006).Small rural catchment on southern edge of North York Moors. Geology: permeable Oolitic Limestone, covered by post-glacial lacustrine clays in south. The upper part is Middle Oolite Grits and Limestone, which dip south under Upper Oolite; this in turn is covered by post-glacial lacustrine clays. The groundwater catchment greatly exceeds the topographical catchment. No known catchment changes.Variation in flows is limited due to the dominant groundwater influence; the Beck is largely spring-fed from Keld Head about 2km u/s. A predominantly natural regime apart from some pumping at Keldhead spring (for public water supply), and some abstractions/returns from cress beds and a trout farm.

Hump and downstream slopes form the control. No cableway. Constructed by diversion of river. Mining subsidence caused the flume to tilt. The flume appears to have been stable since 2002. No known bypassing. Two ratings applied across period of record. Theoretical rating used initially but then structure affected by mining subsidence and current meter rating developed. First rating applied from July 1970, later revision only applied from September 1996 due to uncertainty in timing and impact of subsidence. Rating reviewed in 2019, change due to subsidence deemed likely to only impact at low flows, a revised rating was developed to combine low flow limb from 1970-1996 rating (B) with the high flow limb from current rating (C). This gives improved fit to high flow gaugings, pre-1996 AMAX now significantly increased.1969/70 is only a partial year and likely to have missed AMAX so peak is rejected. Truncation of early charts due to lack of range (1970-72) affected three PoT events, peaks estimated for these and considered reasonable. Pre-1996 high flows reprocessed and increased in 2019 and now considered reliable. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).A catchment draining a lowland, predominantly rural catchment southwest of Chesterfield. Draining both sides of the motorway, the river runs north, close to the M1 for most of its length. Mixed geology comprising Coal Measures, Permian Marls and Magnesium Limestone. Predominantly rural catchment. Substantial areas of mining tips with areas of urbanisation in lower reaches including Bolsover. Decline of coal mining industry over the period of record.Large abstractions made upstream for coal washing affect earlier records, ended with mine closures. Small net import, including sewage effluent and mine drainage.

Replaces 27015. Poor flow correlation between the two sites.Crump weir (20m wide) installed September 1973. Station replaces 27015 which had poor quality data. Crump weir supplemented by in-line path ultrasonic gauge for high flow measurement from 9-11-2001. Peak flows from the headwaters are diverted down the Sea Cut (27033). All data for this site is held against this station number. Larinier fish pass built adjacent to weir in 2013 and hydro-electric turbine installed in 2017. Crossed-path multi-path ultrasonic gauge installed 70m upstream of the weir in 2011, this replaces measurement at the weir from 2013.Crump weir formula accounts for non-modular flow at approx 55 cumecs (1.2m). This was verified using gaugings and ultrasonic flow data. The weir drowns at approximately 1.2m, and is overtopped on the left bank above 1.9m - this may lead to an under-estimation of flows. However, this is small and extrapolation is appropriate. A bund upstream ensures floodplain storage returns through section but flows over 1.9m bypass along a vehicle track and return downstream of the station. The bypassing was estimated to be around 50-60 cumecs in 2000. Peak flow rating derived from gaugings, including two from November 2012 which also included measure of bypass flow and confirm rating extrapolation is good. Single path ultrasonic gauge replaced by crossed-path multi-path gauge in 2011, which measures flows up to 1.9m, but some bypassing occurs above this. Pre-October 1973 data (monthly only) of poorer quality; derives from 27015. Overlap between data at 27041 and 27015 is limited and the flow correlation disappointing. Structure drowned and bypassed in March 1999 & Nov 2000 floods but rating extrapolation does allow for this. Gap in ultrasonics record 4/11/2002 to 30/09/2003. Ultrasonic gauge replaces rated flows from May 2013. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Mixed geology. Limestones and sandstones bordering the Vale of Pickering; Oxford Clay, shale and sandstone to the north, and sands, clay and gravels in the Vale of Pickering. Rural catchment - moorland and forestry dominate in northern headwaters which drain North York Moors. Arable significant in south. No known catchment changes.Catchment shows a slow hydrological response and includes a groundwater component with considerable flood plain storage. Peak flows from the headwaters u/s of Forge Valley (approximately 6.5% of the catchment) are diverted down the Sea Cut (27033). Minor net impact of artificial influences (spray irrigation is appreciable).

Grimwith reservoir impounded 1864.Flashy flow regime substantially influenced by reservoir operation. Grimwith Reservoir originally impounded 1864. Enlargement works commenced 1976 and regulation releases from June 1984. Howvever, there is little impact on high flows. Significant u/s abstraction at Lobwood (from 1970); at low flows the abstraction is compensated by releases from Grimwith Reservoir (measured at 27063) so net impact at Addingham is reduced.

Fish-pass on left bank (11.73m wide and 0.71m lower). Superseded by new Ultrasonic station at Briggswath (27092) 500m d/s in 1998. Good overlap between the two records, although the ultrasonic gauge was unreliable to start with. Station closed January 1998.Broad crested weir with pool and traverse type fish pass 0.7m lower. Low flows are contained in the fish pass. Fish pass restored in September 1993 but no change in rating. Rating based on current meter gauging, reviewed in 2016. One rating now applied to period of record, upper limb modified based on gaugings from 27092 during overlapping period of record, with allowance for tributary inflow between the two locations. High flows now considered much more reliable. Was Flood Studies Report grade B with previous rating. Goes out of bank in largest events.Records from 1952-1970 based on daily 9am gaugeboard reading, flows not reprocessed and thought to over-estimate peaks. Flow records 1970-1976 based on pressure bulb charts rated by formula only and may be inaccurate. PTR installed May 1976 but washed away in flood September 1976, replaced in February 1977 which is start of reliable record. Peak flows pre-1977 marked as rejected. Highest flood in digital archive is March 1979; earlier records show higher peaks in November 1967 and November 1968. These may have been the highest in period-of-record but flows are considered to be overestimated. Most recent rating applied from Feb 1977 and caused flows to be reduced above 1m stage - period of record reprocessed in 2016. A different rating (B) was previously applied from Sep 1993 following works to fish pass. No evidence for a change from gauging records so this rating no longer used. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Catchment draining the North York Moors to the North Sea at Whitby. Permeable headwaters thence mainly Middle Oolite and Middle Lias; the Whinstone Dyke of basalt crosses the catchment from WNW to ESE, and there is extensive glacial Drift cover.Sensibly natural flow regime - no known artificial influences.

Catchment heavily reservoired.Velocity area station approximately 17m wide. Riffle control 50m d/s, may be subject to erosion as the bed is rocky and unstable.There is some suspicion that a downstream gravel shoal has moved, possibly on more than one occasion, altering the stage-discharge relationship. Rated by current meter to 144 cumecs from the bridge at the section (September 2012). Daily flow rating revised in 1999 to account for a change in channel dimensions caused by the 1991 flood. Rating reviewed again in 2014 producing two new ratings pre and post 2009 flood event. Four peak flow ratings across the period of record. Station will need regular re-rating due to shifting control. Good fit to available gaugings though only two above QMED.Daily flows reworked after a flood in 1991 changed channel dimensions. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Geology: mostly Millstone Grit, Sandstones and Shales, with some small inliers of Carboniferous Limestone in Upper Nidderdale. An east-west fault runs along the line of the river. Rural catchment, predominantly grassland, moorland headwaters. No known catchment changes.Heavily reservoired catchment. Some losses to public water supply from Angram / Scar House reservoirs. Gouthwaite compensation reservoir has a substantial effect on flows and is used to maintain dry weather flows.

Limited range Crump profile weir, 15m wide with 0.4m high walls. Ultrasonic gauge installed in 2003 to improve measurement of non-modular flows. Station severely damaged by extreme flood in June 2005 - ultrasonics washed away. Wingwall extended and ultrasonic replaced in July 2007. D/s levels are measured.Wing walls were rebuilt and raised to 1.4m in 2002. No cableway for check gauging but ADCP is now used at high flows. One peak flow rating across period of record based on ultrasonic data and gaugings up to to 50 cumecs with hydraulic modelled limbs above this. Very good agreement with ultrasonic gauge well beyond QMED.Earlier flows may have small under-estimation, although still well contained within banks up to 2.3m stage, so minimal bypass apart from the June 2005 extreme flood. Hydraulic model estimated extreme flood peak in June 2005 to be 384 cumecs (representing a monumental event). Data missing June-October 2005 and during reconstruction (19-06-2006 to 06-07-2007). Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).Predominantly upland catchment draining the Cleveland Hills. Geology of Jurassic beds of Oolite and Lias, dipping southwards. The Liassic beds (mostly shales) form an intier in the upper part of the catchment with the sandstones and shales of the overlying Estuarine series forming the high ground around the catchment. No known catchment changes.Responsive catchment. Sensibly natural regime, no known artificial influences.

Removed from peak flows dataset in February 2018 (WINFAP Files v6).Channel control at medium and high flows as weir is fully drowned. Low modular limit, higher flows are only approximate; check gaugings to QMED. Out of bank flow at high stages, with significant floodplain storage downstream causing variable backwater influence at the weir. Surcharging bridge u/s at high flows. Theoretical daily and peak flow rating up to modular limit. Rating does not allow for non-modular flow reduction or variable backwater and high flow data considered unreliable. Level gauge upstream in Pickering has been calibrated for flow measurement and high flow data from this gauge can be used with more confidence. No allowance for drowning and the few higher gaugings lie off the rating. Catchment drains parts of the North York Moors. Geology: mostly grits and Limestones of the Corallian. Mixed rural land use; moorland in headwaters, arable in lower catchment; extensive forestry. No known catchment changes. No known artificial influences.

Previously a flat-V weir, intended to measure low flows to complement high flow measurement at 27001. Full-range multi-path ultrasonic operating since 1999, replaced previous flat-V weir. The weir was for low flow measurement in conjunction with high flow data from Hunsingore (27001), which is insensitive at low flows. The weir was removed in 1999 and station converted to ultrasonic to improve fish passage. Ultrasonic gauge originally only set to measure up to 100 cumecs, but range extended after June 2000 event (and before October 2000 event) to cover full range. Station suffered problems from siltation, affected low flows. Channel modified in 2001 to address this problem but only partially successful. Station reconstructed as trapezoidal section in 2017/18 again to prevent siltation. Crossed-path multi-path ultrasonic in trapezoidal channel (installed 2018), replaced previous two-stage channel configuration (from 2001), rectangular channel configuration (from 1999) and earlier Flat V weir (12m wide, from 1979). Weir suffered from variable backwater from the Ouse downstream. Original ultrasonic gauge suffered from siltation, mainly affected low flows which are thought to be too high as a result. Section modified and downstream weir removed to reduce sediment deposition (by increasing velocity) but only partially successful. Full rebuild, converting channel to a trapezoid in 2017/18 appears to have resolved this problem. Significant attenuation of peak flows between Hunsingore and Skip Bridge. Flow measured directly by ultrasonic gauge, no rating available since weir removal. Several gaugings >75 cumecs give close agreement with ultrasonic gauge flow.Original Flat V weir rating modified to try to take account of drowning, flows from 1979 reprocessed and high flows substantially reduced. High flows from this period (1979-1999) are still considered unsuitable for flood estimation and are not presented with the peak flows, only ultrasonic peak flow data is presented (from 1999). Low flow data 1999-2018 considered less reliable due to impact of sediment deposition in measuring section, several data gaps in this period also a result of sediment problems. Significant gaps 11/2001 to 05/2002 and 05/2017 to 09/2018 due to site refurbishment. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).Geology: Carboniferous Millstone Grits, Permian Marls and Triassic Sandstones. Predominantly rural, rugged in headwaters. No known catchment changes.Heavily reservoired headwaters of the Nidd valley significantly affect flows; Gouthwaite Reservoir outflows especially significant in drought conditions.
