A variation and feasibility study was conducted in order to implement an approximately 700 metre long system of islands and sidearms and an approximately 900 metre long riverbank renaturation in the Danube stretch between the powerplant Abwinden-Asten and the mouth of the river Enns. The relating excavation material will be used for the optimisation of the mouth of the Enns (restructuring according to a model by the Technical University of Vienna).
Within this project synergies are exploited between the ecological improvements within the meaning of the EU Water Framework Directive and the improved fairway conditions in the port of Enns, resulting in a reduction of necessary dredging works. The project started in 2018 with the contracting and implementation of the application planning.
- In 2019 the planning for submission started. Reconcilements with VHP (Verbund Hydropower GmbH), Ennshafen OÖ GmbH and City Council of Enns were initiated.
The first identified sector (distributary Lang Au - Mitterwasser) was absorbed by VHPs project proposal "LIFE WILDislands".
- For the second identified sector the process for land swap started in 2020. After some discussions the owners agreed on the plan. End of 2020 an experts advice for evaluation of the land was initiated.
The third (Renaturation Schlossau, ca. 500m) and fourth sector (Sporn Ennshafen) are situated on governmental properties, thus no additional planning challenges will arouse.
The project makes a substantial contribution to the implementation of measure
17. Execute restoration measures implementing the EU Water Framework Directive of the Action Programme for the Danube 2022.
