Welcome to the National River Flow Archive

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 including the extensive networks operated by the Environment Agency (England), Natural Resources Wales, the Scottish Environment Protection Agency  and the Rivers Agency (Northern Ireland).

River flow data for ~400 gauging stations can be downloaded from this website. Data for a further ~1000 gauging stations can be requested via our manual retrieval service. The data are available free-of-charge for academic research or educational uses.
