The Wehra Dam (de|Wehratalsperre) is a dam which impounds the River Wehra near Wehr in the county of Waldshut in the German state of Baden-Württemberg. Its reservoir forms the lower basin of the Hornberg stage (Wehr Power Station) and it is thus part of the Schluchseewerk network. The upper basin of the pumped-storage power station is the Hornberg Basin; the cavern with its power station lies inside the mountain about halfway between the two basins.
