European data


Additional information

  1. The map is based on information reported under the second River Basin Management Plans of the Water Framework Directive. These plans were finalised in 2015, and reported in 2016 and 2017. The results cover the period up to 2015.
  2.  RBD: River Basin Districts.
  3. The percentages are based only on known ecological status or potential (i.e. they do not take into account unknown status). Caution is needed when comparing results between Member States as the results can be significantly affected by the methodology applied by individual Member States.
  4. Data sets on surface water body quality for Switzerland reported in the framework of EEA priority data flows are not compatible with the EU Water Framework Directive assessments and are not included in the figure.
