The Werda dam (also: Geigenbachtalsperre ) is a dam in the Free State of Saxony . It is located in the "Geigenbachtal" area of the Werda municipality in the Vogtland district . The closest town is Falkenstein . The dam was built by the city of Plauen from 1903 to 1909 and put into operation in 1910. Between 1896 and 1904 the city of Plauen experienced a strong population increase of 100 percent. The drinking water supply systems used up to now could no longer meet the increased water demand. The dam has served as a drinking water supply for Plauen and its surroundings since 1911, as well as for flood protection .
On picture postcards from the time of commissioning it is reported that an average of 450 workers were involved and that the construction costs amounted to "about 7 million marks". Among the construction workers were Italians and Croats. It was the first dam in Germany to have a directly connected waterworks with a filter system. The dammed body of water is the Geigenbach , which feeds the much larger Pöhl reservoir under the name Trieb .
The main barrier structure of the TS Werda is a curved, jointless gravity dam made of rubble stone masonry from a fruit slate from the surrounding area, which was built according to the Intze principle . The dam was renovated from 1986 to 1991, increased by 3 m (1989–1990) and given a face concrete on the water side. The intze wedge was removed. The storage volume increased to around 5 million m³. Before the wall was raised, the storage space was 3.6 million m³ when the wall was fully blocked and the total storage space was 3.7 million m³ during high water. Since the dam of the pre-dam was also increased, the regional road between Werda and Neustadt, which previously ran over the dam, was relocated uphill behind the dam area. There is also a pump line by means of which water can be drawn here from the Muldenberg dam, which is about 7 kilometers away . Since 1965 there has been a pumping station below the Zahnmühle, which directs water from a nearby stream to the dam.
The dam is a "large dam" according to ICOLD criteria.
The dam has a pre- dam as a process water storage facility and a small reservoir in its catchment area between Grünbach and Poppengrün at the scattered settlement Siehdichfür .
Swimming, fishing and other recreational sports are not possible in the reservoir because the dam is used to produce drinking water. However, visitors can hike the "Geigenbachtalsperre excursion and hiking trail".
