Note this dataset only includes catchments in England and Wales. Scotland is 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; a geographical coordinate reference system (CRS) WGS84 (EPSG 4326) and a projected CRS British National Grid (BNG - EPSG 27700) see `Catchment boundaries for England and Wales based on existing Fish Health Inspectorate (FHI) catchments 2023 - British National Grid (BNG)`_ .. _`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 england and wales based on existing fish health inspectorate (fhi) catchments 2023 - british national grid (bng)`: https://data.cefas.co.uk/view/21966 20240730 20231206
