Sorpe Dam

The Sorpe Dam is a dam on the Sorpe river, near the small town of Sundern in the district of Hochsauerland in North Rhine-Westphalia, Germany.

Together with the Biggesee, the Möhne Reservoir, and the Verse reservoir, the Sorpe Reservoir is one of the major artificial lakes of the Sauerland's Ruhrverband reservoir association. It serves as a water supply, drives hydroelectric generators, and is used for leisure and recreation.
