The Kauscha dam is a dam in Saxony that was built in Kauscha near Dresden in 1977–1979 and 1983–1985 for flood protection and industrial water supply . The official commissioning was in 1985. The dam of the Kauscha dam is a homogeneous dam made of loess loam .
The dam is maintained by the Gottleuba dam and river management company with its headquarters in Bad Gottleuba . The 228 meter long Gebergrund bridge , on which the A17 Dresden – Prague motorway runs , crosses the lake .
The dam primarily serves to protect Dresden- Prohlis from flooding . The reservoir is a flood retention basin for the Geberbach . Of the 0.245 million m³, 0.14 million m³ are intended as a flood retention area. As an early warning, the dam was equipped with a drainage level, an electrical connection and remote data transmission in 2011 for 120,000 euros.
The main users of the process water are the surrounding strawberry fields . In the past, the reservoir was still used for swimming. This is no longer possible today due to siltation and low water levels.
The Kauscha dam system includes two rainwater retention basins on the A17 motorway, which were put into operation in 2005 and have a volume of 226 m³ and 184 m³ respectively when fully backed up.
In a 100-year flood event, the inflow to the dam is around 8.9 m³ / s. The flood discharge up to HQ100 is reduced to around 2 m³ / s by the dam.
