Talsperre Döllnitzsee, reservoir in Germany

The Döllnitzsee dam, also called Talsperre Wermsdorf or Laubethal, is an earth dam built southwest of Wermsdorf in Saxony. It impounds the Döllnitz and the Saubach, and its main dam carries a long, elongated overflow funnel as a flood relief structure. Two pre-dams belong to the system: the Horstsee, covering 72 hectares, and the Göttwitzsee, covering 80 hectares.

The dam was built in 1850 to store water and control flooding. Between 1981 and 1983, it underwent major repairs and reinforcement to ensure its safety and long-term function.

The name Döllnitzsee comes from the Döllnitz stream that feeds the reservoir. Today it serves as a recreation spot where visitors hike, fish, and boat while experiencing nature directly.

The lake is easily accessible with parking, bus stops, and on-site facilities such as restrooms and a snack bar. Visitors find a beach, playgrounds, and grilling areas, with dogs welcome and bicycle and boat rentals available.

The reservoir lies on the Elbe-Mulde watershed, so water from the Horstsee flows not only via the Döllnitz to the Elbe but also through the Saubach and Mutzschener Wasser to the Mulde. The main dam has a long, elongated overflow funnel for flood relief.
