The Densowsee is a natural lake in the Uckermärkische Seen nature reserve in Brandenburg . It is located in the Templin district of Densow in the Uckermark district .
Geography and hydrography
The Densowsee is located in the south of the area of the district Densow, south of the municipality Annenwalde . The Ragösenbach flows into the lake from the north, and it also drains via the Ragösenbach to the Großer Beutelsee .
The lake has a size of 16 ha. The lake level is 49.6 m above sea level. NHN . The lake is not stratified, the trophy index is 2.8, i.e. H. the lake is eutrophic. Other sources give a trophy index of 3.8. The lake is very shallow, the maximum sample depth was 1 m. Other sources give a depth of 1.5 m (Müller & Meier-Brook).
history
As early as 1373, the lake was named stagnum nomine Densow in the land book of Charles IV from 1375 . The medieval village of Densow was not on the site of today's Densow, but on the site of today's Annenwalde on Lake Densow. In the Badinger hereditary registry of 1574 he is called Densaw . In the Urmes table sheet 2846 Gandenitz from 1825 it is already listed as Densow See . The origin of the name is uncertain. Sophie Wauer in the Brandenburg name book is still discussing the possibility of a connection to the water body name Densbek and Densbach and, derived from this, the place name Dens.
