The Ziegelsee is a lake in the west of Mecklenburg-Western Pomerania within the urban area of Schwerin .

Map of Schwerin around 1750, at that time the Ziegelsee was not yet divided into an inner and outer lake

It emerged from a tertiary depression (erosion channel ) in the Vistula Ice Age , which was filled with melt water. It is divided into inner lake and outer lake. The separation was created by building a road on a natural threshold. However, a water connection between the two lakes was left open, which is spanned by a bridge. The south-facing, barely indented inner lake is 0.52 km² in size, has an average water depth of 7.5 m and a maximum depth of 16.5 m. The outer lake, which is particularly well structured in the northern part, is 2.5 km² in size and has a maximum depth of 34.4 m. The Outer Lake is connected to the Schwerin Outer Lake via the Lange Graben (also known as the Wickendorfer Canal). With the channel for Werder Heidensee , a further outflow direction Schweriner interior lake. In the northern part of the Ziegelaußensee are the "Big" and "Little Murrkiten Island".

The Ziegelsee (ZgS) is part of the federal waterway Stör-Wasserstraße of waterway class I under the responsibility of the waterways and shipping office Lauenburg .

history

Port facility with a former warehouse (now a hotel) and an old crane on the Inner Lake

After the First World War, an inland port was built parallel to the expansion of the water connection to the Elbe to promote trade on the east bank of the Ziegelinnensee. Previously, cargo was unloaded from ships on Burgsee or Spieltordamm, the demarcation between Ziegelinnensee and Pfaffenteich . Detergent, general cargo, flour and sugar were transported into the city. Mainly grain was exported. Bricks, manure, animal feed, sea sand, wood and coal were still handled in the port. Due to the lack of a water connection to the Baltic Sea to Wismar that could be navigated by transport ships and the shallow water of the Stör - Elde connection, the port did not acquire great economic importance at that time. The inland port was connected to the railway line to Wismar by track. In 1939 a granary was built at the port. There was an increased turnover of goods after the end of the Second World War. In 1947, the quay wall was therefore extended by 25 to 294 meters. In 1972 200,000 tons of goods were handled. After the reunification , the port lost its economic importance again. A jetty was built at the harbor, and the warehouse was converted into a hotel between 1995 and 1998.

During the GDR era, the discharge of wastewater from two sewage treatment plants in the mental hospital and the mixed water system resulted in pollution of the lake. After heavy rainfall, untreated wastewater flowed into the body of water through overflowing rainwater overflows. Only a sewage treatment plant built in Schwerin-Süd in 1974 brought relief.

Flora and fauna

The outer lake with its near-natural shore areas is part of the EU bird sanctuary "Schwerin Lakes". The Schelfwerder Wald bird sanctuary and the Wickendorfer Moor are located on the west bank. The Ziegelaußensee is very important for the protection of species and biotopes. So there are aquatic plants occurrence of Flowering , Common Hornwort and Straight Horn leaf , bulrush , Myriophyllum spicatum and pondweed (filamentous, grassy, comb and marbled pondweed) and Wasserknöterich . Otters live in the outer lake .

In contrast, the Inner Lake is an almost completely enclosed eutrophic body of water.

Sports facility

In the GDR era, motorboat races were held several times on the Inner Lake . The first race took place on July 19, 1953. The 1957 event was advertised internationally for the first time, and the “Petermänken” challenge award (named after the castle spirit ) was introduced for the winner .

Others

There is a listed park on the north-west bank of the Outer Lake in the area of a clinic site. The park at Wendenhof on the north bank is also a listed building.
