Erken

Erken is a research lake in Stockholm County used for scientific study of freshwater ecosystems. The water body supports ongoing investigations into aquatic life, water quality, and environmental changes affecting northern European lakes.

The university received a farm property from a local donor in 1928, which became the foundation for establishing a research facility on the lake. This donation marked the beginning of scientific monitoring that would continue for decades.

Swedish limnological research traditions developed through studies of water chemistry, vegetation patterns, and freshwater species at Lake Erken Laboratory.

Access to the site is restricted as it functions as an active research facility rather than a public destination. Visitors interested in the scientific work should contact the university directly to arrange any visits or learn about the research programs.

The research station maintains one of Europe's longest continuous records of water measurements spanning many decades of observation. This exceptional dataset provides insights into how freshwater ecosystems change over extended periods.
