This dataset is a subset of "WFD Classification Status Cycle 2" dataset. Overall status is the water body level water framework directive classification derived from combining both Chemical Status and Ecological Status/Potential using the one-out-all-out methodology. This means a water body can only be reported at Good Status Overall if it is assessed at Good Status (or Potential) for both Ecological and Chemical Status. Both natural and artificial or heavily modified water bodies are assessed for Overall Status on a High, Good, Moderate, Poor or Bad basis.
