Talsperre Kriebstein, Reservoir and cultural heritage monument in Mittelsachsen, Germany

Kriebstein Dam is a curved concrete gravity dam on the Zschopau river near Waldheim, impounding the Kriebstein reservoir. Its crest runs 230 m along a 225 m radius curve, with a 22.25 m wall height above the valley floor and 4 m width at the top. The dam is divided by curved vertical buttresses, and a two-part powerhouse with a red flat roof stands below the wall.

Built between 1927 and 1929 and commissioned in 1930, the dam was the first of a series planned in the Weimar Republic's "Golden Years" to improve the water balance and supply electricity. Plans to use the Zschopau's hydropower dated back to before World War I. A sign on the wall still advertises flood protection, though the reservoir's small volume limits that role.

The reservoir has hosted motorboat racing since 1962, when the first DDR championship points race was held; European championships followed in 1965–1967 and a world championship in 1970. Annual German championship races resumed in 2006. The Zweckverband Kriebsteintalsperre runs scheduled and circular boat trips from April to October.

The Zweckverband Kriebsteintalsperre runs scheduled line and circular boat trips on the reservoir from April to October. Marked hiking trails circle the lake, and swimming, sailing and camping are possible along the shore. The dam stands on the Zschopau about 25 km north of Chemnitz, above Waldheim.

The reservoir is fed by the Zschopau, a tributary of the Freiberger Mulde, and its catchment of 1738 km² is the largest of any dam in Saxony. Its spillway can discharge 975 m³ per second, yet the stored volume is so small relative to annual flow that during the August 2002 flood about sixteen times the reservoir's capacity passed through.
