We have been engaged in the national environmental monitoring of lakes and watercourses for over 50 years. We are also national data hosts for parts of the freshwater monitoring.

The national monitoring of lakes and watercourses is described by Fölster, Johnson, Futter och Wilander "The Swedish monitoring of surface waters: 50 Years of adaptive monitoring". Several other articles about the Swedish environmental monitoring is available in the same volume of Ambio (2014:42, open access).

The regional and local environmental monitoring is conducted on commission by various stakeholders and may serve several purposes, such as providing time series of reference character and monitoring various kinds of impact.
