Water Resource Availability Data

Natural Resources Wales

The Water Resource Availability data is based on a nationally consistent method and provides a national picture of Water Resource Availability for each Water Framework Directive Cycle 2 water body. Local Water Resource Availability for abstraction licensing is provided in our Abstraction Licensing Strategies (ALS) published on our website. ALS outline the implications for abstraction licensing of the different water resource availability colours.

This national picture of Water Resource Availability may be different to local assessments in ALS particularly for regulated rivers and rivers designated as Special Areas of Conservation (SACs) where local requirements may mean that results have been overridden.

 Water Resource Availability Descriptions

-          Green: Water available for licensing

-          Yellow: Restricted water available for licensing

-          Grey: Heavily modified water bodies (and/or discharge rich catchments

This data is not raw, factual or measured. It comprises of estimated or modelled results showing expected outcomes based on the data available to us.
