power plant

The reservoir is primarily used to generate electricity and to equalize the water output by the Biggetalsperre power station . The hydropower plant with two Kaplan turbines in the natural stone- clad power house has an output of 2.2 megawatts , is used to cover peak loads and produces around 3 million kilowatt hours annually. The power plant is operated by Lister- und Lennekraftwerke GmbH .


Today the Ahauser reservoir, which stretches from Ahausen Castle to the Schafsbrücke below Schnellenberg Castle , is the quietest of the three Attendorn dams. The other two are the Listertalsperre and the Biggealsperre. Fishing is possible at the reservoir. Every year there is a race of pirates , a popular boat class instead.

The small Attendorn-Finnentrop airfield is located north of the reservoir .
