Verbund HydroPower built fish bypasses at the hydropower plants Schwabeck and Lavamünd at the river Drau. Flussbau iC carried out the local construction supervision. The passes were finished in October 2015.
The fish bypass in Schwabeck has a length of 635 m, split in 158 pools and reaching a height of 20.54 m, which makes it the highest fish bypass in Europe so far. For the altitude difference of 10 m at the hydropower plant Lavamünd, a bypass with 74 pools was built. The fish passes will support the recovering of the original biodiversity in the river Drau.
