The Upper Mur River is considered one of the most ecologically valuable rivers of Austria. Its systematic regulation began at the end of the 19th century to intensify agricultural land use. Restoration measures started in 1997 and various projects facilitated the renaturation of the river. The project highlights the importance to reconcile key needs for nature conservation with demands for renewable energy generation from small hydro power plants.
This project is a good example to demonstrate the new "river policy" in Austria that adopts "river restoration" approaches, rather than "river engineering" techniques.
