Fish bypass for the Abwinden-Asten power plant on the Danube
As part of LIFE Network Danube, the Abwinden-Asten power plant on the Danube is being upgraded with a modern fish bypass.

Danube cycle path diversion necessary at the Abwinden-Asten power plant
Construction work on the near-natural bypass stream is in full swing. For safety reasons, the existing R4 cycle path will be diverted for the duration of the work so that cyclists, walkers and other recreational athletes can continue to use the Danube cycle path. Diversion signs indicate the temporary cycle path. The access road to lake Ausee is also specially signposted.

Fish bypass for the Abwinden-Asten power plant on the Danube
Abwinden–Asten power plant lies some 7 km downstream from the centre of Linz and will be upgraded with a fish ladder on the right bank. It is intended that the fish ladder be constructed as a semi-natural bypass stream. With the exception of the lowest section, it is situated in the "TRAUN-DANUBE-WETLANDS" flora-fauna-habitat and bird conservation area. Under normal flow conditions, the stream will bridge a total difference in height of 9.3 m between reservoir area and tailrace.
In accordance with the best available international technology, the access lies downstream from the turbine outlets. It thus ensures that the fish ladder can be located with ease, especially for the spawning migration of Danube fish species that love current (nase, barb and also Danube salmon).
