Munich grapples with Isar flood as river surpasses warning level 1
The Isar river in Munich is currently experiencing high water levels, reaching alert level 1 as of late July 2025. This development is due to the recent extreme rainfall in the region, which has caused concern for potential flooding and overflows in the city.
Forecast and Alert Levels
The Isar river is currently at alert level 1, indicating heightened vigilance for potential flooding. Authorities are actively monitoring the situation and responding by activating large reservoirs to manage and discharge floodwaters, aiming to mitigate further flooding.
Affected Areas
The river and surrounding areas in Munich and broader Bavaria are impacted by the increased flow and flood risk. While specific neighborhoods or districts within Munich aren’t detailed, urban areas close to the river may be at some risk.
Precautions Advised
Residents are advised to stay informed through local news and official flood alerts due to the ongoing elevated alert level. It is advisable to avoid the riverbanks and low-lying areas near the Isar, as water levels can rise quickly during heavy rain events.
Additional precautions include warnings for homeless people about the water in the high bed of the Isar from a water level of 200 centimeters, and potential closures of the Flauchersteg and the Marienklausensteg in the Isar river if the alert level 2 is reached.
Additional Context
Despite the flood concerns, recreational activities like surfing on the Eisbach—an arm of the Isar—in Munich’s Englischer Garten have resumed recently after a closure earlier this year. However, participants should remain cautious due to variable river conditions.
Current Situation
As of 9:30 AM, the current water level in the Isar river in Munich is at 263 centimeters. The Water Management Office predicts more rain and isolated thunderstorms throughout the day. The peak flows in the catchment area of the Isar river have been exceeded. The water level is expected to remain at alert level 1 until Wednesday.
