The Dunkelsee is a natural lake in the Stechlin nature reserve . It lies entirely in the district of Dollgow , a district of the municipality of Stechlin in the Ostprignitz-Ruppin district ( Brandenburg ).

Location and hydrography

The Dunkelsee is located about six kilometers east-southeast of Rheinsberg and about 2.3 km west of Dollgow. The next settlement is Heinrichsfelde , which is about 1.2 km away as the crow flies. The Dunkelsee lies almost entirely in the forest, with a swamp area in the southwest. It can only be reached via a forest path. The lake level is 57.6  m above sea level. NHN . It has an area of ​​about four hectares.

In 1950 the Dunkelsee was classified as Hecht-Schleisee IIc, which means visibility depths of 2 to 5 m in summer. The vegetation is almost exclusively chandelier algae (Characeae). In 1993 the Dunkelsee was classified as mesotrophic. In the Dunkelsee there are: fine candelabrum alga ( Chara virgata ), horn-leaved candelabrum alga ( Chara tomentosa ) and star candlestick alga ( Nitellopsis obtusa ). Investigations into the water constituents of the Dunkelsee in 2004/05 revealed that there are geogenic saline deep waters in the Dunkelsee.

history

The Dunkelsee was mentioned as the Dunckersehe as early as 1530, and in 1784 it was called the Dunker See. It was around this time that the name Dark Sea appeared. In the Schmettauschen map series it is recorded as Hülbselken See . On the Urmes table sheet 2943 Rheinsberg from 1825 the lake is nameless. The adjective dunker from mnd. dunker = dark is occasionally used in dialect for dark.

Stechlin nature reserve

The Dunkelsee is located in the Stechlin nature reserve and is a total reserve. The protective purpose is the maintenance and development ... of a calcareous mesotrophic lake including the adjacent nutrient-poor silting communities, moorland and mixed slope forests as well as the development of pine forests into natural forest communities.

Reinhard Müller, on the other hand, describes the Dunkelsee as one of the most nutrient-poor and unproductive shallow lakes in Brandenburg.
