The Weßlinger See (pronounced: Wesslinger See) is a lake in the village of Weßling in the Starnberg district in Bavaria .


Its origin is based on the region's ice age. It was probably formed as a dead ice hole during the Würm Ice Age , when part of the glacier tongue that excavated the basins of Lake Ammersee and Lake Starnberg broke off and the piece of ice was undermined by the dynamics of the ice mass under the ice flow . Due to the weight of the glacier, it was pressed deep under the bed into the sedimentary rock and was covered with sediment carried along . When the glacier tongues melted, this depression, which was created by the later melting dead ice , as it was covered by the thick layer of sediment and not directly accessible to solar radiation and its radiant heat, remained as an almost circular lake, a so-called Söll .

Environmental conditions

The Weßlinger See is an isolated lake. This means that it has no natural inflows or outflows and is only fed by underground springs. For this reason there is no naturally grown fish population in it. Fish, which were used again and again out of economic interests, sometimes died in the past due to a lack of oxygen. This was favored by heavy bathing traffic and intensive agriculture, which fertilizes the surrounding fields to a large extent. To keep the lake from tipping over , an oxygen pump was installed in the middle of the lake at the end of the 1970s, which pumps oxygen-enriched compressed air into the lake and thus aerates the deep water. Similar to a geyser , it lets a jet of water shoot up in a fixed time rhythm.


The lake used to be owned by Count Toerring zu Seefeld . In 1968 he sold it to the community of Weßling for 200,000 German marks.
