Waterbase - Lakes

Note: new version is available!
Topics: ,
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

European data

Waterbase-Lakes: Quality

The Quality table contains data on nutrients and organic matter in water measured at WISE-SoE lake monitoring stations. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressures data. Each record has five special quality assurance fields. Their meaning is explained in the QA documentation which can be found in the "Additional information" section.

Metadata

Additional information

Waterbase contains timely, reliable and policy-relevant data collected from EEA member countries through the WISE-SoE data collection (formerly known as Eionet-Water and Eurowaternet) process. WISE-SoE data collection selects validated monitoring data from national databases and adds information on the physical characteristics of the water bodies being monitored and on the pressures potentially affecting water quality. The added value of Waterbase is that data collected through the WISE-SoE data collection process are from statistically stratified monitoring stations and groundwater bodies and are comparable at the European level. Waterbase data are primarily used in the production of the EEA's indicator-based factsheets.
