The Danube power plant Greifenstein will be equipped with a new fish bypass in the course of the EU LIFE+ project “Network Danube”. A near-natural stream will help the fish to traverse the 10 metre-high barrier of the Danube power plant. Necessary for this is a 4.4 kilometre-long channel that bypasses the existing, ecologically valuable areas. About 180,000 m³ of gravel have so far been moved in the wetland at the Greifenstein power plant.
The removal of barriers to fish is just one of the goals in the “LIFE+ Network Danube” project. The main objective is the connection of existing, ecologically healthy areas as well as land restoration projects. The Greifenstein fish bypass lies in the European conservation area “Tullnerfelder Donau-Auen”, the biggest continuous wetland area in Austria.
