The new NRFA peak flow data service replaces HiFlows-UK. In April 2014, working with the EA, SEPA, NRW and the Rivers Agency, responsibility for the provision of UK national flood peak data was transferred from the former HiFlows-UK initiative hosted on the Environment Agency’s website to the NRFA. The dataPeak Flow - Winter 2014 Flooding harmonisation has been completed for key metadata, including: station numbers, river names, station names, geographical locations and station types. Harmonisation of station descriptions and other core information will take place in 2014/2015. The NRFA peak flow data service is fully integrated into the existing NRFA website, allowing users to easily search, view and download data.
Guidance on how to use the new service can be found here.
