## Notice

The National River Flow Archive's Peak Flows Dataset (NRFA-PFD) forms a key strategic national asset, underpinning most flood estimation calculations in the UK. The NRFA-PFD refers to the complete UK-wide dataset - with contributions from the Environment Agency (EA), Natural Resources Wales (NRW), the Scottish Environment Protection Agency (SEPA) and the Department for Infrastructure - Rivers (DfIR - covering Northern Ireland). NRFA-PFD ensures that data and information on peak flow data are openly available and consistent across the UK to a wide range of stakeholders. The current contract for this service ends in March 2026, and a new four-year contract is needed to maintain the service until March 2030.
