The mouth of the Traisen river near Traismauer in Lower Austria is a fascinating example of how technology and nature can successfully come together. Here, the Traisen river meets the Danube, but it wasn't always as idyllic as it is today. Originally, the Traisen flowed into the Danube about 7.5 kilometers further upstream. With the construction of the Altenwörth Danube power plant in the 1970s, everything changed: As the water level of the Danube was raised for the power plant, the Traisen could no longer flow naturally. Therefore, a completely new riverbed had to be dug for it.

At approximately 12.5 kilometers, the Altenwörth Fish Bypass is the longest of its kind in Austria and was built between 2019 and 2022 as part of the LIFE Network Danube Plus project. It allows fish such as huchen, schied, and zingel to bypass the Altenwörth Danube power plant and provides a continuous connection to the tributaries, the Kamp and Krems. The near-naturally designed bypass stream, with shallow water zones, gravel banks, and deadwood, also creates new habitats for numerous animal and plant species. The facility is also of interest to cyclists: Along the Danube and its adjacent waterways, natural paths offer views of renaturalized landscapes, small bays, and ecologically valuable rest areas. It is a successful example of how flood protection, energy use, and biodiversity can be reconciled.

One of Austria's longest fish bypasses was created between Altenwörth and Greifenstein as part of the "LIFE Network Danube Plus" project. The approximately 12.5-kilometer-long, near-naturally designed bypass stream allows fish such as huchen, zebrafish, and schied to migrate freely along the Danube and connects important habitats in the tributaries of the Kamp and Krems. Between 2019 and 2022, approximately 34 hectares of new aquatic areas were created, featuring shallow water zones, gravel banks, and deadwood areas – also for kingfishers, otters, and other protected species. In addition to its ecological benefits, the area is now also attractive to recreational travelers: Along the waterway corridor, natural banks, small bays, and viewpoints invite visitors to linger – a successful example of the combination of nature conservation, water development, and sustainable tourism.
