Catchment Abstraction Management Strategy (CAMS) Boundaries
Catchment Abstraction Management Strategies (CAMS) assess the amount of water available in each river catchment. The CAMS Boundaries are an external reference dataset giving an indication of where technical assessments of water abstraction have been undertaken. CAMS helps to look at the balance between society, the economy and the environment. The technical assessment helps identify where water may be available for future use but also where water resource demands may be impacting the water balan

Useful for
- Use cases llm-inferred
- Regional screening of Welsh catchments to see whether a site lies within an abstraction assessment area · Context mapping of water resource pressures for a Wales-wide water balance or abstraction review · Early-stage site screening before commissioning catchment-scale abstraction assessments
- Audience llm-inferred
- hydrologists · water resources engineers · flood consultants · planners · GIS analysts
Limitations
- Constraints docs-verified
- National (Wales) scale only; not suitable for detailed technical assessments · Indicative external reference dataset, not an authoritative assessment of water availability · No scheduled update frequency
