. Its only link to the Baltic is the drainage ditch of the Ahlbeck stream. As a result of natural silting-up processes it is today a shallow lake. In the centre it has a depth of only one to two metres. In addition the lake has lost a lot of its former area. Originally it purportedly reached as far south as Nistelitz. The name of the lake comes from the settlement of Schmacht to the southwest, but which no longer lies on the lake shore. The Ahlbeck, which drains the lake into the Baltic Sea, was canalised in the 1950s. The mouth of the pipe or ditch is located on the beach of Binzer Strand and is marked by an information sign. A variety of animal and plant species live on the lake and, including 40 species on the
