Untere Herbringhauser Talsperre, former reservoir in Germany

The Untere Herbringhauser Talsperre was a small dam south of Langerfeld in Wuppertal, built as a stone embankment with a concrete core. It held drinking water for the city below the larger Obere Herbringhauser Talsperre until 2006, when the dam was partially demolished for safety reasons. The pump house below the dam survives and is a protected monument.

Built in the late 1920s and opened in 1928, this facility provided extra drinking water storage for Wuppertal. Its construction required relocating the small settlement of Hilgershammer, and it shaped the valley for decades until safety concerns led to its partial demolition in 2006.

This place marks a time when the city secured its water supply through modern engineering. Visitors can trace the story of water management here and observe how nature returns after the dam's removal.

The site is open to visitors and offers quiet walking paths around the former reservoir area. The trails are easy to walk and provide good views of the valley's natural recovery.

The dam was a stone embankment with a concrete core. Its 2006 demolition, ordered by the Düsseldorf district government, was carried out without a formal planning approval procedure because the structure no longer met flood protection standards for a statistically once-in-5,000-years event. Several hiking trails over the dam crest, including the Wuppertaler Rundweg, had to be rerouted.
