Our floodplain focus

December 2024

Work on the new Aufhausener Lacke is making progress:

The ‘new’ Aufhausener Lacke is being developed as a near-natural floodplain water body. Once completed, the still water body will remain in existence for decades and serve as a valuable habitat for fish and water birds as well as amphibians and insects in the Inn floodplains. It will be equipped with shallow water zones and deep areas.
By connecting the deep zone to the Inn, fish will also be able to use the Aufhausener Lacke as a habitat again. And the shallow water areas will once again provide a perfect environment for fish larvae and juvenile fish as well as for waterfowl.

First breeding record of the red-necked grebe on the Inn since the 19th century

The sightings took place between May and July 2024. The ecologists commissioned by VERBUND were even able to observe a pair of red-necked grebes mating. Afterwards, only the male was present in front of the reeds, suggesting that the female was hiding near the nest, as is usual for this species.

‘The pleasing sighting of the red-necked grebe shows how important intact floodplain waters are for water birds. As part of the ‘Riverscape Lower Inn’ nature conservation project, VERBUND is ensuring that there will be even more and better breeding habitats for the red-necked grebe and other birds along the Inn in the future,’ says VERBUND project manager Roland Schmalfuß.

Egglfing-Obernberg Inn power station receives a fish migration aid

21 October 2024

Preparatory work starts in October

A few weeks after the opening of the Braunau Simbach fish migration aid, VERBUND is starting preparatory work for the next bypass water around 30 kilometres downstream at the Egglfing-Obernberg Inn power plant. This nature conservation project is also part of the EU LIFE project ‘Riverscape Lower Inn’, which further promotes the near-natural development of the river landscape on the Lower Inn.

In 2025, construction work will begin on the largest near-natural bypass on the Inn to date with a length of 5.8 kilometres. The ground-breaking ceremony for this pioneering nature conservation project is expected to take place in spring next year. Before this can happen, the entire construction site must be cleared. The necessary clearing work will begin at the end of October and is scheduled to last until the end of February. The remaining preparatory measures will be completed by the end of May 2025 at the latest.

As a first measure, hollow trees that serve as valuable habitats will be carefully removed and reintegrated into nature at other suitable locations. All of the work will be carried out in close coordination and under the supervision of an ecological construction supervisor and has been agreed with the authorities.

23. September 2024: Next milestone reached in establishing river continuity on the Inn

After just under a year of construction, the new fish migration aid enables all species of fish in the River Inn to swim past the Braunau-Simbach power plant or stay there for a while. For the first time since the construction of the power plant, the new bypass water allows them to freely reach the tributaries or floodplain waters again. The bypass also provides new habitats: wood, stones and above all gravel form typical river structures in the water and on the banks. Habitats are created for fish, birds, insects and amphibians. In addition to the fish migration aid, a natural riverbank was created on the Inn downstream of the power station. Fish migration and habitat development are documented scientifically on an ongoing basis through extensive monitoring.

Johann Springer (Mayor of Kirchdorf), Michael Amerer (VERBUND Wasserkraft Managing Director), Kurt Vallée (Deputy District Administrator of the Rottal-Inn district), Karl Heinz Gruber (VERBUND Wasserkraft Managing Director), Klaus Schmid (Mayor of Simbach), Johannes Waidbacher (Mayor of Braunau) hold the LIFE flag together. In the background you can see the fish migration aid surrounded by trees in bright green.

Trial operation started for Fish migration aid at the Braunau-Simbach Inn power plant

July 2024: First trial carried out successfully!

After a construction period of around one year, the new fish migration aid at the Braunau-Simbach Inn power plant has been completed and was filled with water for the first time on July 10, 2024.

Trial operation begins with the first water dotation. During this time, all relevant discharge scenarios are tested. During the initial flooding, the new water bed is slowly filled with a small amount of water and, once the bed is saturated, a continuous discharge situation begins to develop. In addition to the installed sealing elements, the sediment load of the Inn causes a slow process of self-sealing in the new watercourse.

During trial operation, the flow conditions at different discharge volumes are checked and, if necessary, the watercourse is reworked together with the construction supervisor. The bypass has a variety of structures such as gravel zones, pieces of wood and stones as habitat features. The embankments of the stream bed, which will be increasingly integrated into the existing landscape, serve as a habitat for birds and insects.

Once the trial operation has been completed successfully, the flow rate of the new, three-kilometre-long fish migration aid will be determined according to the seasons with discharges of between 2,000 and 6,000 l/s.

The official opening and commissioning is planned as part of an open day on September 21, 2024. By then the remaining work on the accompanying paths and the installation of railings will be completed.

Natura 2000 Day: District President visits new Braunau-Simbach bypass watercourse

On May 21, 2024, leading decision-makers from Bavaria and Upper Austria were informed about the construction progress of the new bypass watercourse at the VERBUND Braunau-Simbach power plant as part of the Natura 2000 Day.

Natura-2000 Family Day

May 21st, 2024

Floodplain adventure afternoon with the Natura 2000 rally

On May 21, 2024, a floodplain adventure afternoon for families will take place at the Waldsee in Kirchdorf am Inn (Bavaria) around the Braunau-Simbach Inn power plant. Young and old can discover the ecological measures implemented in the river landscape as part of the EU LIFE Riverscape Lower Inn project and experience them with the "Natura 2000 Rally".

Throughout the area there are informative and entertaining experience stations:

  • Learn more about the "LIFE Riverscape Lower Inn" project with VERBUND and explore the new bypass water at the Braunau-Simbach power plant with guided tours.

  • Naturium on the Inn

  • Children's adventure station of the Bavarian Academy for Nature Conservation and Landscape Management

  • Life in the Inn at the bypass with fish you can touch

  • Meadow habitat at and on the Inn dams

  • Observing birds at the forest lake with spotting scopes

VERBUND, the Bavarian Academy for Nature Conservation and Landscape Management (ANL) and the Naturium am Inn are the organizers of the action day to mark European Natura 2000 Day.

LIFE Riverscape Lower Inn realizes improvements for plants and animals with the closure of the "ice channel".

March 2024

The "ice channel" is a connection between the main branch of the Inn and an oxbow lake, also known as the "Heitzinger Bucht". Through this connection, around 8,000 m³ of fine sediment enter the old Inn water system every year, causing turbidity and sedimentation. The habitats now benefit from the closure of the ice channel. Greater depths of visibility and higher water temperatures in the oxbow lakes will encourage the growth of aquatic plants and improve the habitat for bird, amphibian, fish and insect species.
