Overview
- The iconic standing wave has been unusable since a late‑October cleanout removed sediment and left the channel bed smoothed, according to local reporting.
- Specialists from Helmut‑Schmidt University are conducting measurements to analyze current patterns and the subsurface conditions.
- Immediate attempts to revive the wave by changing the inflow and briefly adding more Isar water produced no improvement.
- Further technical options under review include narrowing the outflow and returning gravel to the channel to rebuild the bed profile.
- Officials say the cause is not yet clear, with fluctuating Isar levels and the wave’s sensitivity to small flow changes noted, as access issues persist after a prior fatality and the city negotiates a land swap to improve legal entries at E2.
