Technical Challenges

As part of the so-called Iller Strategy 2020, numerous ecological measures have already been implemented on the upper Iller between Altusried and Lautrach in recent years. Near-natural bypass streams have been created at the five barrages. They allow fish to migrate in the river and provide valuable habitats themselves. Bedload management is another measure of the Iller strategy to ecologically enhance the section of the river.
