The National River Flow Archive Application Programming Interface (NRFA API) provides access to NRFA river flow data and metadata. Through the API a number of data types are available including; gauged daily flows, catchment daily rainfall and peak flow data. Also available is access to NRFA river flow gauging station information, including station metadata (the type of station, its location and key characteristics) and information about the station's catchment (land use, geology, climate, etc.).
