Wehr Reservoir

The Wehra dam of the Wehra near Wehr in the district of Waldshut in Baden-Württemberg is a dam made of rubble material with an asphalt concrete outer seal. It was built from 1971 to 1974 and commissioned in 1975. A second tunnel west of the dam serves to relieve the flood. As the lower basin of the Hornberg level (Wehr power station), it is part of the Schluchseewerk. The upper basin of the pumped storage power plant is the Hornberg basin; the cavern with the power plant is located in the mountain about halfway between the upper and lower basins. The Wehra flows out of the reservoir via an inlet structure through a tunnel in the slope to the east of the barrier structure. Initially, the hydropower was not used to generate electricity. Between 1998 and 2000 an additional small hydropower plant with an Ossberger turbine was installed. This has a maximum output of 1,135 MW. The height of fall varies between 16 and 36 meters depending on the water level in the reservoir. The average height of fall is 29 meters.
