Due to the piping of the Walger Franz stream and a small drop structure, the entrance for fish to the small stream was impossible. To improve fish migration the water authority Weilheim removed the pipe and the drop structure. In the event of flooding, it is now possible for fish to withdraw from the powerful flow of the Isar.
