The Frauenau drinking water dam in the Bavarian Forest was completed in 1983 to secure the drinking water supply. As there is a lack of groundwater in the Bavarian Forest due to the geological situation, a water reservoir was built which is fed by the rivers Kleiner Regen and Hirschbach. Up to 15 million m3 of water are made available annually via the water extraction tower. If the water level is too high, an overflow funnel prevents the lake from crossing the dam.
The dam is 86 meters high.

Origin: The dam was built between 1974 and 1984 (it went into operation in 1983).
The almost 85 m high dam (at the time of construction the highest rock rubble dam in the Federal Republic of Germany), dams the small rain to a lake with almost 22 million m³ content.
The water stored there is primarily used for the public water supply.
It is removed from the lake via the extraction tower, mostly 21 m above ground, and fed to the processing plant on the Flanitzalm.
Purpose: Flood water is to be caught in the dam, but it can also drain completely via the manhole overflow in the southwest of the lake.
Locks at Hirschbach and Kleiner Regen hold back driftwood and leaves before the reservoir. ", Source: bayerischer-wald.de/Media/Attraktionen/Trinkwassertalsperre-Frauenau
