Note this dataset only includes catchments in Scotland. England and Wales are represented as a single area. For complete coverage of England, Scotland and Wales use `Catchment boundaries for England, Scotland and Wales based on existing Fish Health Inspectorate (FHI) and SEPA catchments (WGS84) 2023`_ There are 2 versions of the dataset; this one a geographical coordinate reference system (CRS) WGS84 (EPSG 4326) and one projected to CRS British National Grid (BNG - EPSG 27700) see `Catchment boundaries for Scotland based on Scottish Environment Protection Agency (SEPA) catchments British National Grid (BNG) 2023`_ .. _`hydrological sections for england, scotland and wales with associated river catchment 2023, water framework directive (wfd) waterbody and regional information (wgs84)`: https://data.cefas.co.uk/view/21968 .. _`catchment boundaries for england, scotland and wales based on existing fish health inspectorate (fhi) and sepa catchments (wgs84) 2023`: https://data.cefas.co.uk/view/21749 .. _`catchment boundaries for scotland based on scottish environment protection agency (sepa) catchments british national grid (bng) 2023`: https://data.cefas.co.uk/view/21969 20240730 20240704
