The National River Flow Archive (NRFA) is the UK's focal point for river flow data. The NRFA collates, quality controls, and archives hydrometric data from gauging station networks across the UK maintained by the Environment Agency, Natural Resources Wales, Scottish Environment Protection Agency and Department for Infrastructure - Rivers. There are over 1,600 gauging stations equating to 22 million flow values. The longest records stretch back to the late 19th Century. Our river flow data are used to underpin much of the hydrological research and water resources development and management activity in the UK.
The NRFA holds daily mean flow data, peak flow data and catchment average rainfall data, alongside a wealth of metadata, spatial information and photographs all gathered together in one place to provide context to the community when using the data.
