The Tüttensee is a tote lake in the area of the communities Grabenstätt and Vachendorf in the Bavarian Chiemgau . The littoral zone of the lake has various silting phases and has partially fen -character. There is a species-rich landscape conservation area on the shore . The lake has a small drainage channel in the northwest to the Marwanger Bach and is one of the warmest lakes in Upper Bavaria . There is an excursion restaurant with a lido on the south bank.
description
The Tüttensee lies in a kettle of ice that was created when the Chiemsee glacier retreated after the height of the last ice age . It is located in a well-preserved structure of Ice Age Kame gravel terraces that are completely wooded. Echo sounder measurements by the Bavarian State Office for Water Management show a flatter southern part and the deepest part of the lake with a maximum of 17.3 meters in the northwest.
68 hectares of the lake and the bank area are designated as a landscape conservation area. According to this, entry is prohibited on the ecologically particularly valuable south and east banks outside the lido, and swimming or boats are not permitted directly in front of the bank section.
In the 1980s, the lake suffered from massive nutrient input from a small ditch draining into it, draining agricultural land. Fishing had to be restricted. A 2-hectare sewage pond proposed by the District Office in 1989 could not be implemented for cost reasons. The Bund Naturschutz joined the project in 1995 and, with public funding, implemented a significantly more cost-effective plant- based sewage treatment system in conjunction with a gravel bed on partly leased and partly purchased areas on the lake. Together with a decrease in the use of fertilizers on the adjacent agricultural land, the biological treatment of the inflow resulted in a significant improvement in water quality. The lake is still classified as eutrophic . Since then, the gravel areas of the facility have been an important biotope for the region.
The Tüttensee has been designated as a geotope by the Bavarian State Office for the Environment under the designation "Ice Decay Landscape of Tüttensee" .
Research history
At the beginning of the 20th century, Wilhelm Halbfaß carried out soundings on the Tüttensee from a boat, determined a maximum depth of 16.2 meters and created a depth map that already corresponded almost exactly to modern investigations. The geology of the area including the Tüttensee was presented by Carl Troll in 1924 when the first scientific description of the Inn glacier was made . The lake was later the subject of studies on the ice break-up landscapes of the Bavarian Alpine foothills several times .
In 2004, the Tüttensee was associated with the hypothesis of the so-called Chiemgau impact and its formation as an impact crater was postulated. The Bavarian State Office for the Environment then carried out a drilling and 14 C-dating . These showed that the formation of the moorland and silting up of the Tüttensee have been progressing undisturbed for over 12,000 years, which proves that the Tüttensee was formed during the Ice Age and prevents an interim impact.
