Data Waterbase - Lakes
Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment published Oct 2012
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. The average nitrate concentration in European rivers decreased by approximately 11% between 1992 and 2010 (from 2.5 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being more than halved between 1992 and 2010 (54% decrease). Also average lake phosphorus concentration decreased over the period 1992-2010 (by 31%), the major part of the decrease occurring in the beginning of the period, but is still ongoing. The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Press Release Europe’s bathing waters continue to improve
Ninety-four per cent of bathing sites in the European Union meet minimum standards for water quality, according to the European Environment Agency's annual report on bathing water quality in Europe. Water quality is excellent at 78 % of sites and almost 2 % more sites meet the minimum requirements compared to last year's report.

GIS Map Application Macrophytes in lakes
The map shows the ecological status or potential of European lakes and reservoirs, expressed using a specific biological quality element (BQE), namely macrophytes, reported by EEA member countries via WISE. The ecological status class is assessed by each country according to their national classification system, following the principles established by the Water Framework Directive (WFD). The assessment may be based by one or more samples taken during the year of reporting. The map displays the latest reported information under the WISE SoE reporting, so the year of reference may vary. Note that under the WFD reporting, the ecological status or potential based on all BQEs combined is represented by the BQE with the worst class - the "one-out-all-out" principle - which does not apply here, given that only one BQE is represented and that the reporting is done annually. The purpose of the map to enable the user to compare values per country or per monitoring station, depending on the scale of visualisation.

Publication EU 2010 Biodiversity Baseline
The EU 2010 Biodiversity Baseline provides facts and figures on the state and trends of the different biodiversity and ecosystem components. It thereby supports the EU in developing the post‑2010 sub‑targets and provides factual data for measuring and monitoring progress in the EU from 2011 to 2020.
