UK Surface and Groundwater Archives (SAGA) Committee

The NRFA is mandated by the UK government (Defra) and the devolved administration of Northern Ireland, Scotland and Wales to maintain a comprehensive archive of UK river flows and provide information on water resources nationally. The UK Surface and Groundwater Archives (SAGA) Committee was setup in 1982 following transfer of the national surface and goundwater archive to the Institute of Hydrology (now the Centre for Ecology and Hydrology) and British Geological Survey. The liaison committee provides a forum for discussion between stakeholders in UK hydrometric monitoring and helps impart a strategic overview of the activities of the National River Flow Archive (NRFA) and National Groundwater Level Archive (NGLA). The Committee comprises representative of national administrations, hydrometric Measuring Authorities, the Met Office, the water industry and professional societies.
