Percentage of water bodies not in good ecological status or potential, per river basin district

The figure shows, at country level, the percentage of water bodies that are not in good ecological status or potential per river basin district. The map is based on information reported under the Water Framework Directive as part of countries’ third river basin management plans. The percentages are based on surface water bodies with known ecological status or potential (i.e. they do not include water bodies with unknown status). Caution is needed when comparing results between countries, as results can be affected significantly by the methodologies used by individual countries.
