Ecological status is an assessment of the quality of the structure and functioning of surface water ecosystems. It shows the influence of pressures (e.g. pollution and habitat degradation) on the identified quality elements. Ecological status is determined for each of the surface water bodies of rivers, lakes, transitional waters and coastal waters, based on biological quality elements and supported by physico-chemical and hydromorphological quality elements. The overall ecological status classification for a water body is determined, according to the ‘one out, all out’ principle, by the element with the worst status out of all the biological and supporting quality elements. More dashboards are available below the main dashboard.

More information

Caution is advised when comparing Member States and when comparing the first and second RBMPs, as the results are affected by the methods Member States have used to collect data and often cannot be compared directly.

In addition, further information is provided in a  Draft guide to dashboards on ecological status; in chapter 2 of the EEA report European waters – assessment of status and pressures 2018, and section 2.4 Ecological status and exemptions of the WFD 2016 reporting guidance.

Further information on surface water ecological status or potential is available in following dashboards:
