The Dürrlohsee , also called Dürrlochspeicher or Dürrloh pumped storage facility , is an artificially created body of water in the Bavarian administrative district of Upper Palatinate south of Mühlhausen in the Dürrloher Heide parcel .

geography

The lake is located in the Franconian Jura one kilometer south of Mühlhausen in the groundwater bed of the confluence of the Sulz and the Roßbach at an altitude of 415  m above sea level. NN . In the north the terrain rises steeply to the 573 m high Schlüpfelberg . Federal highway 299 , the Sulz and the historic Ludwig-Danube-Main Canal run to the west . Immediately to the southwest is the Bachhausen lock of the Main-Danube Canal , to which it gives off its water; to the west is a solar park and the Mühlhausen area .

history

The Dürrlohsee was planned as a Dürrloch pond for agricultural and fishing purposes in the Middle Ages . Originally it had an area of ​​0.4 hectares and was fed exclusively by precipitation and groundwater inflows. In the 1980s it was expanded to fifty times its area to the north as part of the construction work on the southern ramp of the Main-Danube Canal. Since then it has mainly been filled with pump water. The new systems went into regular operation on September 25, 1992. In 1995 the bottom was also asphalted and flooded again in 1996.

today

The Dürr Lohsee presents today at the summit level of the Main-Danube Canal is necessary in order smuggling operation water of the canal sure he to be water at Channel kilometers 115.5 via a drainage channel near the head of the thrift lock emits Bachhausen. The natural inflows are insufficient for the enormous amounts of water required for this. Therefore, at low tariff times (at night and on weekends), additional water is pumped from the Altmühl and Danube regions into the lake via the southern stretch of the canal . The lake is filled from the Berching section via the Bachhausen pumping station at the lower head of the lock there. 85% of the storage volume of approx. 2 million cubic meters can be transferred to the sewer. With this amount of water, 16 locks per day could be carried out for a week without operating the savings basin, without further pumping. In the process, the water level drops from the storage target 415.5  m above sea level. NN to the lowering target of 407.75  m above sea level. NN from.
The lake is fenced and is not available for water sports or swimming purposes due to the large fluctuations in the water level and the risk of suction.
