The controlled basin is located directly above the spa town of Wippra in the district of Mansfeld-Südharz, protects 21 villages from flooding and is the central component of the flood protection concept (HWSK) for the Wipper. The barrier structure consists of a dam with an ecologically continuous culvert structure in which the operational outlets and spillways are integrated. A quarry in the Wipper valley approx. 2 km upstream of the barrier was excavated for the extraction of the supporting material.
