Nussdorf power plant lies between Samerberg and Wendelstein in the former glacial lake of the Rosenheim basin. The lacustrine deposits under the river gravel therefore form the base of the barrage. The pier power plant with its raft foundation is ideal in that it evenly distributes the load on the erosion-sensitive lacustrine deposits.
Two 25-meter wide turbine piers and three 18-meter wide weir fields are alternately arranged along an axis transverse to the river and rest on a two-tier base. The weir openings are closed with 12-meter high, hydraulic oil operated radial gates and weir flaps.
The 7.50-meter high impounding dams made of sand and gravel run along both sides of the river which was straightened in the last century. The dams tail off after 7 km on the left bank and 9 km on the right bank where they are sealed with a concrete surface. The gravel layer, which forms the base of the dams, is sealed with a thin diaphragm wall. The landscape remained largely unchanged.
The revitalisation of the oxbow arms, which dried up after the river bed was lowered and were transformed into wetlands following the construction of the dams and the subsequent rise in the groundwater level, largely restored the former river ecology.
