UK National River Flow Archive


The NRFA is hosted by the Centre for Ecology & Hydrology. The archive acts as the main focal point for hydrometric data in the UK, providing stewardship of, and access to, daily, monthly and flood peak river flow data from over 1,500 gauging stations across the UK.

The NRFA collates, quality controls, and archives hydrometric data from gauging station networks across the UK including the extensive networks operated by the Environment Agency (England), Natural Resources Wales, the Scottish Environment Protection Agency and the Rivers Agency (Northern Ireland). NRFA data also include catchment rainfall totals, derived from Met Office data, and various spatial data sets (e.g. digital elevation data, land cover, geology and hydrogeology), developed by CEH and the British Geological Survey (BGS).
