The Jettenbach power plant is equipped with a fish bypass and has a continuous flow. All hydropower plants on the Inn comprise:
• the machinery hall with the turbines
• the weir systems for flood release
• the dams and dikes for the accompanying flood protection, and,
• the pumping stations and ditches, which guarantee agricultural use that existed before construction of the barrage.
The VERBUND hydropower plants on the Inn are therefore not only plants for electricity generation but also ensure flood protection in the region. VERBUND also focuses on improving the ecological conditions at individual sites and on restoring natural river landscapes. We implement a large number of measures in this regard: from creating continuity of flow with fish bypasses through to giving structure to bodies of water and connecting tributaries. In order to guarantee habitats for fish with all their habitat requirements, management of the gravel banks in the near-natural fish bypass or below the dam stage is additionally carried out. The maintenance of sediment continuity through sediment management, a topic of the EU Water Framework Directive (WFD) for species conservation in man-made rivers, is also an important component for the long-term conservation of fish fauna.
