The dam and its two barrages , theHorstsee (72 ha) and the Göttwitzsee (80 ha) are used for the supply of industrial water , for flood protection , for fishing and for recreation . The barrier structure of the Döllnitzsee dam and the pre- dams are earth dams . At the main dam there is a large, elongated overflow funnel as flood relief . The dammed waters are the Döllnitz and the Saubach.
The reservoir is located on the watershed between the Elbe and Mulde . That is why the water from the Horstsee not only flows to the Döllnitz and the Elbe, but also to the Mulde via the Saubach and Mutzschener Wasser .
For some of the data mentioned in the table (construction times, height, content and area) there is also different information.
