The small hydropower plant Staufensee is in Dornbirn , Vorarlberg , Austria , at the northern end of the Staufen lake , next to the Rappenloch bridge befindliches small hydroelectric power plant and one of the power stations at the Dornbirner Ach .
The power plant Staufensee utilizes the head of the Staufensee dam (1893/1894) of 22 m and is most Staufensee, next to the power plant plane sand , the second power plant which uses the water power of the Dornbirner Ache in this area. After the Rappenloch Gorge there is another water intake for the hydropower plant in Gütle and, subsequently, there are several small hydropower plants on the Müllerbach .
power plant
Machine house
The machine house , in which the turbine, the generator and the control of the Staufensee power plant are located, is located directly under the heavy weight dam of the Staufensee. The engine house is designed in such a way that it can withstand flooding and backwater from the Dornbirner Ache (Ebniter Ache). The maintenance of the Staufensee hydropower plant is the responsibility of Kleinwasserkraftwerk Staufensee GmbH.

geology
Due to the considerable entrainment of floating debris caused by the marl inclusions ( Helvetic system ) in the mountains of the catchment area of the Ebniter Ache / Dornbirner Ache, large amounts of silt and other biogenic substances, such as branches, are deposited in the Staufensee. This would quickly lead to the silting up of the reservoir if no appropriate measures were taken. The Staufensee was rehabilitated in the 1970s and in 1977 the bottom outlet blocked by floating debris was exposed again.
Due to the reduced drainage possibility since the rock fall in the Rappenloch on May 10, 2011 and the associated increase in the level of the water flow in this part of the Rappenloch Gorge, normal discharge of alluvial material from the reservoir due to floods as of 2016 is hardly possible. There is a risk of the reservoir silting up in a few years. This would also have a direct impact on the functioning of the Ebensand power plant and the Staufensee hydropower plant.
