Catchment boundaries for England and Wales based on existing Fish Health Inspectorate (FHI

Catchment boundaries for rivers in England and Wales are derived from hydrological sections and aligned with existing Fish Health Inspectorate (FHI) catchments. The dataset provides complete coverage of waterbodies under the Water Framework Directive for England and Wales, with Scotland represented as a single area. It is published by the Government Digital Service and is available in two coordinate reference systems: WGS84 and British National Grid.

Use Cases

• Map hydrological units for environmental impact assessments based on catchment boundaries.
• Analyze waterbody coverage for Water Framework Directive compliance based on the described complete coverage.
• Integrate spatial data for fish health monitoring based on alignment with Fish Health Inspectorate catchments.

Strengths

• Derived from a referenced hydrological sections dataset, suggesting a structured source.
• Includes complete coverage of Water Framework Directive waterbodies for England and Wales.
• Available in two standard coordinate reference systems (WGS84 and British National Grid).

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset coverage is limited to England and Wales, with Scotland represented only as a single area.
