Figure Proportion of classified surface water bodies in different RBDs holding less than good ecological status or potential, for rivers and lakes
The figure shows percentage of the total number of classified water bodies.

GIS Map Application Macrophytes in lakes
This map shows the ecological status (i.e. status or potential) of macrophytes in European lakes (i.e. lakes and reservoirs) potentially impacted by eutrophication. The ecological status class of a country's waterbodies (or stations) is assessed by each country according to their national classification system, following the Water Framework Directive. The assessment may be based by one or more samples measured during the year of reporting. The purpose of this map is to show ecological status of individual biological quality elements (BQEs) and the major impact types. In comparison, the map layer "Ecological status or potential of water bodies" in the WFD Surface Water Viewer (http://www.eea.europa.eu/themes/water/interactive/soe-wfd/wfd-surface), displays ecological status or potential based on all BQEs combined, represented by the BQE with the worst class (the "one-out-all-out" principle). Moreover, the maps based on SoE-WISE biological data will be updated yearly, whereas the WFD database will be updated every 6th year.

GIS Map Application Phytoplankton in lakes
This map shows the ecological status (i.e. status or potential) of phytoplankton in European lakes (i.e. lakes and reservoirs) potentially impacted by eutrophication. The ecological status class of a country's waterbodies (or stations) is assessed by each country according to their national classification system, following the Water Framework Directive. The assessment may be based by one or more samples measured during the year of reporting..

GIS Map Application Total phosphorus in lakes
The map shows the mean annual concentrations of total phosphorus (TP) as mg/L TP in European lakes and reservoirs measured at Eionet-Water Lake monitoring stations during 2011. Total phosphorus includes all phosphorus components in lake water: phosphate dissolved organic phosphorus and particulate phosphorus in algal and bacterial cells, as well as in mineral particles (e.g. clay). For most countries the concentration values are based on measurements over the whole year, but for some countries the annual mean actually represents only the growing season (due to ice cover in winter).

Figure Proportion of classified water bodies in different RBDs affected by pollution pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)
The percentage is based on total number of classified water bodies. See the indicator specification for more details.

Figure Phosphorus concentrations in lakes (total phosphorus) between 1992 and 2011 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean concentrations for river monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). There were no stations with complete series after inter/extrapolation in the South and Southeast regions. The number of lake monitoring stations included per geographical region is given in parentheses

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2013
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2005. On average, the nitrate concentration in European rivers declined by 0.5 mg N/l over the period 1992 to 2011 (20% relative to the average concentration), 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- On average concentrations declined by 0.08 mg P/l between 1992 and 2011 (72% decrease relative to the average concentration). Also average lake phosphorus concentration decreased over the period 1992-2011 (on average by 0.008 mg P/l, or 27% relative to the average concentration). 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.
