Integrated WB & CAMS AP sub-catchments

The Integrated water body (WB) layer covers England and breaks it down into manageable areas from which we can monitor water resource availability. Each water body is either a Water Framework Directive (WFD) water body or a Water Resources Geographical Information System (WRGIS) water body. WRGIS water bodies are a combination of WFD water bodies and additional Assessment Points (AP). Attribution statement: © Environment Agency copyright and/or database right 2015.
