The Nehmitzsee is located in the north of Brandenburg in the immediate vicinity of the Großer Stechlinsee within the Rheinsberg lake area . The lake covers an area of 171 hectares, 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 village of Nimitz, which had already become desolate in the Middle Ages , which can be translated as "village of the Germans".
The lake, which is rich in bays and has no outflow, is only about ten meters sunk into the sands of the Fürstenberg ice rim. Until the 18th century , the Kleine Rhin , which had been developed into a raft ditch , branched off from the Nehmitzsee and flowed into the Rhin south of Rheinsberg . In 1745 the Polzow Canal was built, which connected the Stechlinsee with the Nehmitzsee and continued largely within old ice-age channels over the Roofensee to the Havel . Despite the installation of several locks, the water level in the Nehmitzsee fell to a large extent. The area of the lake decreased significantly and the Little Rhin fell permanently dry. Several small lakes near the Nehmitzsee, such as the Wulwitz and Breutzensee, used to be connected to it. The Polzow Canal, which was abandoned as a waterway as early as 1786, only carries water at the exit of the Nehmitzsee in rainy years.
In the mid-1960s, the Rheinsberg nuclear power plant was built between the northern tip of the Nehmitzsee and the Stechlinsee . To supply the power plant with cooling water, the old Polzow Canal was widened between the two lakes and a second canal was built north of it. Nehmitzsee water was pumped through this cooling water channel into the Stechlinsee. From there it reached the Nehmitzsee again via the Polzow Canal. This artificial water cycle had an impact on the flora and fauna of both lakes. The consequences for the Nehmitzsee were largely positive, as clear Stechlinsee water regularly flowed through it. After the power plant was shut down in 1990, the cycle no longer exists.
