Daily flow data for the water year 2020/2021 are now available to download from the NRFA for most stations in the UK.
This annual update contains new record flows for a number of stations, shown on the map below. It displays new record low flows (minimum daily flows) in red and new record high flows (maximum daily flows) are shown in blue.
Some stations are currently still undergoing the annual quality control process, and will be updated on the NRFA in due course. Where more recent river flow data are required, users may be able to source this by contacting the relevant Measuring Authority, or by looking at the Live data tab which is available for most stations in Scotland, and many stations in England.
For the yearly update of data, the daily flow data are provided to the NRFA by Measuring Authorities through an annual submission programme. Data for each water year are normally submitted to the NRFA the following spring, after which it undergoes detailed quality control before being added to the national archive.
Peak flow (AMAX and POT) data for water year 2020/2021 will be released later this year. The most recent release of files for use in WINFAP are available to download from our website.
