Data

ICP Waters is a collaborative programme involving circa 20 countries in Europe, plus the USA and Canada. The core dataset comprises around 250 river and lake monitoring stations, some of which have more than 30 years’ worth of surface water data.

The map below shows the locations of the main ICP Waters sites, together with basic catchment properties. A more comprehensive overview map, including summary statistics and trend analyses for key surface water parameters, can be found on the data exploration page.

Please note that, due to the difficulty of reconciling data licencing agreements from nearly 20 countries, this website only provides data visualisations and statistical summaries. In many cases, the raw datasets themselves are available to download from national agency websites – please see the useful links page for more details.

Data submission

Information regarding how to submit data to the ICP Waters programme can be found on the data submission page. If you are not currently involved in the project, but have relevant data you would be willing to make available, please let us know.
