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 .
