Overview
- Raising the Eisbach’s inflow, including routing water from the Köglmühlbach, did not reestablish a surfable wave as of Wednesday evening.
- The city reports that gravel was brought in and the water level was increased, yet the feature remains turbulent whitewater and unsurfable.
- The Wasserwirtschaftsamt is now taking flow and level measurements across interconnected city streams, with coordination between the Baureferat, Stadtwerke and the IGSM.
- Next options under review include regulating the downstream level, further adjusting in‑ and outflows, and potentially adding more substrate, with external hydraulic expertise consulted.
- The Baureferat says no structural changes were made during cleaning; the cause remains unclear, with experts noting low Isar inflow and the wave’s sensitivity to small geometric and depth changes as plausible factors, and new safety lighting has been installed following an April fatality.
