Perlsee, Artificial lake in Bavaria, Germany

Perlsee is an artificial lake in Bavaria created through dams and engineered banks to serve as a water reservoir for the region. The water body is managed through technical systems that regulate water flow and levels.

Perlsee was built in 1962 on the upper reaches of the Böhmische Schwarzach near Waldmünchen, impounded by a 580 m earth dam. It was created for flood protection, hydropower generation and recreation, and is operated by the Wasserwirtschaftsamt Regensburg. Its 115 kW hydropower plant produces electricity; the reservoir covers about 21 hectares at 494 m elevation.

The lake is a popular local recreation spot: a beach with lawn, campsite, lakeside restaurant, minigolf, beach volleyball, pedal boats, rowing, windsurfing, sailing and fishing, plus a trim trail and high and low rope courses. In winter people come to ice-skate and play ice stock sport. Swimming at the southern shore is free but has no sanitary facilities.

The lake lies on the upper Böhmsche Schwarzach near Waldmünchen, held back by a 580 m earth dam. A bathing beach with lawns and sanitary facilities is on the shore, while swimming at the south shore is free but has no sanitary provision. Marked hiking trails run along the banks and around the whole lake.

The reservoir is held back by a 580-metre earth dam and operated by the Regensburg water authority; its 115 kW hydropower plant is one of three reservoirs in the area, alongside the Silbersee near Treffelstein and the Eixendorfer See. The lake lies at 494 metres above sea level on the upper reaches of the Böhmische Schwarzach.
