The power plant at Feldkirchen has been passable since 2015. To make it easier for fish to find the fish bypass connected to the Hammerbach, which flows parallel to the Inn, special river structures were built in the Inn. A gravel substrate was also brought in for spawning grounds, as well as nutrient-poor grassland sites, crude soils, ponds and embankments on the banks, e.g. for the local yellow-bellied toad.
The gravel bed and juvenile fish habitat at the location are managed in cooperation with the Technical University of Munich.
The Feldkirchen power plant consists of a three-field weir system, the powerhouse with three sets of machinery and a 110 kV outdoor switchgear.
Each set consists of a Kaplan turbine and a directly coupled umbrella-type generator.
The weir system has four openings with a width of 15 metres each. The weir gates consist of wheel-mounted gates with flash weir (tilting gates).
The main inflow in the backwater area is the Mangfall. The dams on the left bank of the Inn near Schechen and along the Hammerbach and Rott rivers provide flood protection for the Rosenheim area. The Mühltal flood defence and the Vogtareuth dam were built on the right bank.
Flood hollows in the area of the foreshore bring about a lowering of flood levels by increasing the discharge cross-sections. No water flows through them at low water.
