    Description of solution
    Summary (Challenges; Objectives)

    Section 1 concerns the area immediately below barrage 23.The power plant represents a barrier for water organisms, which is why the continuity is to be achieved with the aid of a fish bypass. The possibility of flooding the floodplain forest via the Fischbach can contribute to the vitalization of the floodplain. At the moment, it is largely cut off from flood events by the strong deepening of the river Lech. On the eastern side of the Lech there is the opportunity to remove the bank protection so that the river can successively break up the bank. This mobilizes additional bed load which counteracts the deepening. Here, the drop structure is in conflict with a near-natural development and must be removed. On this side of the river, there is the option of relocating the dyke to give more space for river bank erosion and to connect additional riparian forests. On the western side, the bank will remain fortified to protect the drinking water supply and will be designed as close to nature as possible. A river bed ramp in the underwater part of barrage 23 will ensure the stability of the structure. It can be designed either as a rough ramp close to nature or as a deliberately impassable fall to show ascending fish the way to the fish migration aid. The measures are part of the project Licca Liber.
