Stausee Niederhausen, Reservoir and listed monument in Niederhausen, Germany

The Stausee Niederhausen is an impoundment of the Nahe at Niederhausen in the Bad Kreuznach district. A three-field weir near the former railway station raises the water, which flows through a 760-metre canal called the Obergraben to the hydroelectric power station built in 1926–1928. The weir and machine house are protected monuments, and the water surface lies entirely within the Nahetal von Boos bis Niederhausen nature reserve.

Wasserkraftwerke Niederhausen GmbH built the hydroelectric plant and its three-bay weir near the former railway station between 1926 and 1928. The weir raises the Nahe so that water flows through a 760-metre canal, the Obergraben, to the power station. Until the 1990s part of the dismantled Glantalbahn railway carried goods to the plant.

The reservoir lies entirely within the Nahetal von Boos bis Niederhausen nature reserve, and the weir and machine house are protected monuments. In long frost periods the reservoir can be opened for ice skating, a use locals watch for each winter.

The weir, machine house and water surface lie inside the Nahetal von Boos bis Niederhausen nature reserve, so paths and banks are reached on foot from Niederhausen. In long frost periods the reservoir may be opened for ice skating. The former station near the weir marks the starting point of the 760 m Obergraben canal.
