The Gottleuba dam is a dam that dams the river of the same name in the Eastern Ore Mountains. The dam is the core of the system of flood protection systems in the Gottleuba river system, which has been built since the 1950s . In addition to flood protection, it serves to supply drinking water for the Pirna area and, to a lesser extent, to generate electricity.
history
The Eastern Ore Mountains, and here in particular the catchment areas of Gottleuba, Müglitz and Weißeritz , are among the classic flood formation areas in Saxony. Floods in the Gottleuba region can be traced back to 1480, and over the centuries heavy precipitation with devastating flash floods, which caused great damage and claimed numerous lives, can be proven. Serious damage occurred in particular during the floods in 1927 , when well over 100 people died in the Gottleubatal alone.
Initial considerations and plans for the damming of the Gottleuba river in the area above the former Haselberg hammer mill came into being after the floods in the 19th century (1825, 1858, 1860 and 1890). After the floods in 1890, the communities in the Gottleubatal were already drafting a dam near the future location above Bad Gottleuba at an estimated cost of 900,000 marks.
However, the realization was only advanced after two successive floods in 1957 and 1958 caused damage in the Gottleuba valley. For sustainable flood protection, several retention basins ( Buschbach , Mordgrundbach , Friedrichswalde-Ottendorf , Liebstadt ) were built in the Gottleuba river system from the end of the 1950s .
The core of the protection system, however, is the Gottleuba dam, which was built between 1965 and 1974 above the former Haselberg hammer mill (commissioning 1974, completion 1976).
The dam of the Gottleuba dam is a straight gravity dam made of concrete. According to the height of the barrier structure above the lowest point of the foundation level, it is the highest dam in Saxony in front of the Eibenstock dam .
Between 2007 and 2009, the top of the wall was extensively renovated and the dam and river management building was rebuilt. The measure cost around € 7 million.

tourism
Above the dam there is a lookout point from which you can see the reservoir. The dam itself is only accessible to the public on selected dates. Swimming and recreational sports in the reservoir are also not possible, as it is a drinking water reservoir, but hiking around the reservoir is possible.

The dam has a pre- dam at the inlet of the Gottleuba in Oelsengrund, which is also a concrete gravity dam and has a 50 m wide overflow in the middle of the wall.
