Administrative Boundaries - Water Management Areas
Water management boundaries are delineated to river catchments. The Environment Agency uses these areas for their flood, water management and water quality operational purposes. The areas are attributed with the long and short name of the area, the area code, the name and address of the area main office. The data also includes look ups for the previous Water Management region and area names, and the current Environment Agency Public Facing area names and codes, for each area. Attribution stateme

Useful for
- Use cases llm-inferred
- Identify the EA water management area and area office for a site during flood risk assessment · Reconcile legacy EA region and area names with current Public Facing names in older project data · Overlay operational flood and water quality boundaries on catchment-scale GIS studies · Derive area office and main office contacts for enquiries and consent-related correspondence
