Overview
- The city increased inflow on November 5, including diversions from the Köglmühlbach and the Isar, but no surfable wave had formed by afternoon, with effects expected to appear only after a delay.
- Mayor Dieter Reiter calls restoration a top priority and outlines a staged plan that could move from higher inflow to underflow regulation and, if needed, adding gravel to rebuild the wave profile.
- Officials from the city, the Wasserwirtschaftsamt, the municipal utilities, and the IGSM held coordination talks, and discharge and gauge data are being collected across the connected stream system.
- The cause remains unclear, with possibilities including excessive gravel removal during cleaning or fluctuating Isar levels affecting a sensitive hydraulic balance.
- New lighting was installed at the site as a safety measure following an April fatality, with surfing hours set from 5:30 to 22:00.
