The Luhne-Lengefeld flood retention basin is a dam in northwest Thuringia between Mühlhausen and Lengefeld . The water from the Luhne is held back in the normally empty basin during high tide .

The dam was built from 1951 to 1953 and the entire system was commissioned in 1955. It is an earth dam that is divided into three zones. It has a berm on the water side and on the air side . The dam is sealed from the subsurface with a spur and a sealing curtain (injection curtain). The building site consists of shell limestone, marl limestone, clay, boulder clay, shale and limestone.

The operating facilities include an inlet structure , a gravity tunnel , a slide shaft in the middle of the dam with two slide valves , a stilling basin and a flood relief system .
