Lemonroyd Weir River Gauge - Oulton, UK - River Gauges on Waymarking.com

The River Aire is partly canalised with stretches that bypass weirs etc on the river.

This gauge is at Lemonroyd Weir that was built after the river burst its banks and flooded a coal mine. Part of the river had to be diverted and this is part of the new stretch formed after the diversion.

There is a bridge across the river here.

RIVER GAUGE INFORMATION: Grid Reference: SE381281 Hydrometric Area: 27 - Ouse (Yorkshire) Catchment Area: 865 km2 Measuring Authority (local station number): Environment Agency - Yorkshire (F1702) Station Level: 18 m AOD Station Operating Period: 09/1985 - N/A Station Summary Description: Triangular Crump weir with fish pass. Replaced Fleet Weir. All data held against this station number. NHMP Index Site: No FEH indicative suitability: Pooling General Description: Flow Record Description: Triangular Crump weir (approx. 27m wide) with fish pass. No cableway. In 1993 it replaced Fleet Weir 320m u/s. Fleet Weir, built 1985, is a 35m wide Crump weir with a fish pass (not used). Fleet Weir drowns as a result of backing up from Lemonroyd. Both gauges are located downstream of Leeds but upstream of the major confluence with the Calder. A serious bank breach in March 1988 inundated the adjacent open cast coal mine and was attributed to geological fault. After the breach Lemonroyd was built in a 3km long, S-shaped cut through meandering river channel, further from opencast mine. Fleet Weir had shown evidence of movement prior to the inundation event. All data (for 27080 and Fleet Weir) held against this station number. Flows above Qmed are diverted >600m u/s of gauge through St Aidens Washland, flows return to the Aire downstream of the gauge. The offtake to the washland was completed in 2012 (although the washland used prior to this). Data for 06/09/1985 to 11/08/1995 from Fleet Weir; 11/08/1995 to present from 27080. All data held against this station number. December 2015 flood peak thought to have been significantly delayed and reduced as a result of flow into the St Aidan's washland upstream. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7). WEB LINK FOR RIVER GAUGE: [Web Link] ANY ADDITIONAL WAYPOINT: Not Listed
