Hydrometeorology of the Lake Stechlin areaclimate in the lake’s region, the water temperature, heat balance, amount of evaporation and light penetration of Lake Stechlin, and the water balance of the catchment area. Of particular interest are the changes caused since 1967 due to the operation of a nuclear power plant affecting the water tem

In the following sections we will give basic data about the phosphorus, carbon, nitrogen, silicium and oxygen content of the water characterizing the chemical state of the lake system before and during the operation of the nuclear power plant.

Flora and fauna of the Lake Stechlin areaself is not older than 12 000 years. This represents a very brief period for the post-glacial flora and fauna to have produced new species, and our lakes under investigation generally show a very low level of species differentiation. The present flora and fauna are mainly the result of present envir
