Nehmitzsee

The Nehmitzsee is located in the north of Brandenburg in the immediate vicinity of Lake Stechlin within the Rheinberger 's lake region. The lake covers an area of 171 acres, has an average depth of 6.4 meters and a maximum depth of 18.6 meters. The name of the lake is derived from the already desolate has become in the medieval village Nimitz, which can be translated as " village of the / of the Germans".

The indented endorheic lake is sunk only about ten feet into the Sander Fürstenberger ice stage. Until the 18th century branched off from the Nehmitzsee to Floßgraben developed Small Rhin, which flowed south of Rheinberg in the Rhin. 1745 Polzowkanal was built which connected the Stechlinsee with the Nehmitzsee and more largely resulted in old glacial grooves on the Roofensee to Havel. Despite the incorporation of multiple locks it came in Nehmitzsee to a water level reduction greater magnitude. The area of ​​the lake decreased significantly and thereby the Small Rhin fell permanently dry. Several small lakes near the Nehmitzsees how the Wulwitz and the Breutzensee were previously associated with it. The 1786 as a waterway, was abandoned Polzowkanal only leads at the output of Nehmitzsees in rainy years water.

Mid-1960s, was built between the northern tip of Nehmitzsees and the Stechlinsee the nuclear power plant Rheinberg. For the cooling water supply to the power plant of old Polzowkanal was extended between two lakes and built north of it a second channel. This cooling water channel Nehmitzseewasser was pumped into the Stechlinsee. From there it was taken across the Nehmitzsee Polzowkanal again. This artificial water cycle had an impact on flora and fauna of both lakes. The consequences for the Nehmitzsee were largely positive, as he was regularly traversed by clear Stechlin seawater. After switching off the power plant in 1990, the circuit no longer exists.
