The Rottauensee, also called Rottstausee or Postmünster reservoir, is a reservoir near Postmünster in the Rottal-Inn district. In 1954, the Rott flooded 7,000 hectares of agricultural land and caused buildings and bridges to collapse. The flood of 1965 also caused damage. The Free State of Bavaria built a retention basin near Postmünster from 1968 to 1973. At the same time, a hydroelectric power plant with an output of 300 kilowatts and a standard output of 1.1 million kWh per year was built. The system consists of a Kaplan shaft turbine and a synchronous generator and was completely renovated in 2008.[1] Boat dock near Postmünster. The Rottauensee serves as a local recreation area for the town of Pfarrkirchen. There are numerous sports and leisure facilities around the lake, especially golf and mini golf courses as well as tennis courts. Swimming, sailing and surfing are possible on the lake.
