Extracted from N2K Diffuse Water Pollution Plans Catchments data alongside WFD catchment data, River Basin Management Plans and Surface Water Catchment mapping in consultation with Area Teams, LPAs and Environment Agency.N2K Diffuse Water Pollution Plans Catchments (DWPP) data used as well as Water Framework Directive (WFD) Surface water datasets and Ordnance Survey (OS) Terrain for use in the SSSI Catchment Tool. These datasets were also used by Councils to generate their own mapping using local knowledge and their in house tools. Datasets were occasionally extended to estuary boundaries or to exclude parcels which local knowledge of hydrology proved to be inaccurate, with guidance from Area Teams (Natural England and Environment Agency).
