Talsperre Dröda, reservoir in Germany

Talsperre Dröda is a large reservoir in the Vogtland region of Saxony built across two river systems to store water for surrounding communities. The concrete wall extends over 375 meters and rises more than 50 meters high, with water behind it forming two elongated basins whose shorelines vary from shallow areas with aquatic plants to steep drop-offs into deeper water.

Construction of the reservoir began in 1964 and ended in 1971, with a concrete wall built to supply water to surrounding cities including Plauen, Oelsnitz, and Adorf plus approximately 35 additional communities. Completion of the dam marked a turning point in the region's water management and required the relocation of about 170 homes and farms along with the repositioning of roads and cemeteries.

The reservoir is also called Feilebachtalsperre after the Feilebach it dams. During the Cold War, indicator ponds were stocked with fish at the inflows from Bavaria to signal chemical contamination; the largest, near the destroyed village of Troschenreuth, survives as the Troschenreuth pre-basin. Today angling is the only permitted sport on the water.

The dam crest is closed to the public, and water sports and swimming are not allowed; fishing is the only permitted activity in and on the reservoir. A hiking trail crosses the saddle dam of the Ramoldsreuth forebay, which is the way to reach the water on foot.

The reservoir supplies drinking water to more than 35 communities while simultaneously functioning as flood protection through controlled release of excess water. Additionally, a small power plant generates electricity, allowing the dam to contribute to local energy supply alongside its primary water management role.
