Daily flow data for water year 2016/2017 are now available to download from the NRFA for most stations in the UK.
Some stations are still undergoing the quality control process and data for stations in Hydrometric Areas 10-20 have not yet been submitted to the NRFA. Where more recent river flow data are required, users may be able to source this by contacting the relevant Measuring Authority, see here for more information.
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 2016/2017 will be released later in the year. The most recent release of files for use in WINFAP are available to download here.
