A fish bypass was successfully integrated into the Adriach weir system of the Peggau power plant in 2015. The 270 metre-long fish ladder consists of a vertical slot pass and a near-natural bypass channel. The height difference to be overcome between the headwater and tailwater is approx. 5.3 metres.
