Haunetalsperre, Water dam in Fulda, Germany

The Haunetalsperre is a small dam and flood-retention basin on the Haune river near Marbach, in the Fulda district. Its earth-fill embankment dam, 230 m long and 14 m high, is built of broken Buntsandstein with an asphalt seal and a 85 m long diaphragm wall. The reservoir normally covers 15.2 ha and can expand to 75.4 ha at full flood capacity.

The dam was constructed in the 1980s to control frequent flooding of the Haune river in the region. The project emerged from the need to protect communities from repeated flood damage.

The reservoir has become part of the local recreation network, drawing people to walk and cycle in the surrounding area. The shores offer different views of the landscape and connect to broader regional pathways.

The site is best visited on foot or by bicycle and works well for day trips from the surrounding area. Wear sturdy shoes since paths can be uneven, and weather conditions can change quickly by the water.

A small hydroelectric facility operates at the dam, generating power during flood management operations. This system turns water movement into electricity when water levels are high and water must be released.
