The Buschbach flood retention basin is used for flood protection in the Gottleuba catchment area in Saxony. The flood retention basin is located near Hellendorf near Bad Gottleuba-Berggießhübel . The Buschbach, which flows over the Bahra and Gottleuba into the Elbe, is dammed. It is a drying basin with normally no water, which was commissioned in 1963. Today it is operated by the state dam administration of the Free State of Saxony.
The dam is a straight earth dam with an inclined inner seal made of clay and a 21 m deep sealing curtain .
The flood retention basin was built after severe damage in two floods in 1957 and 1958. In 1897 and 1927 there was already flooding in this area of the Eastern Ore Mountains .
