LAKE MUGGELSEE AND ITS ENVIRONMENT - NATURAL CONDITIONS AND ANTHROPOGENIC IMPACTS

Lake Muggelsee, a polymictic eutrophic lake at the eastern border of the city of Berlin (area: 7.3 km2, mean depth: 4.9 m) is mainly influenced by the River Spree (flowing through the lake) and subject to various usages, especially to municipal water supply and recreation. Geomorphologic development, morphometric features, climatic conditions, hydrological regime, and position in the hydrographic net are described. Short information is given on fauna and flora of the lake, and on characteristics of the catchment area. Water quality parameters are summarized as 12 year average (1979-1990) and the eutrophic state is compared to other lakes. Finally, a short report on scientific research activities is given.
