Flood Warning for Bode and Ilse - Harz Mountains face rising flood risks as snowmelt and rain swell rivers

Warmer weather has arrived in the Harz Mountains after weeks of freezing conditions. The sudden rise in temperatures is now causing snow to melt rapidly, raising concerns about river levels in the region. Authorities have issued flood warnings for the upper reaches of the Bode and Ilse rivers, along with their tributaries.

The Bode river, which begins in the Harz Mountains and flows through the Magdeburger Börde, has seen low water levels in recent weeks. Measurements taken on February 20-21, 2026, recorded just 117-118 cm at Ilse-Hoppenstedt and a flow rate of 0.159 m³/s at Ilse-Ilsenburg. Despite these low readings, earlier warnings were issued on January 26 due to critical water gauge conditions.

The German Weather Service predicts temperatures will climb to 13°C (55°F) in the coming days, with no frost expected, even at higher elevations. This thaw, combined with rain forecast for Sunday and scattered showers on Monday and Tuesday, is likely to push water levels up. The Saxony-Anhalt Flood Forecasting Center has already warned that some gauging stations may exceed the first flood alert threshold.

The flood warning will remain active until at least next Tuesday. As the snow continues to melt, rivers in the area are expected to rise noticeably, particularly in the upper sections of the Ilse and Bode.

The combination of warmer air and rainfall is set to increase water levels along the Bode and Ilse rivers. Residents and local authorities are advised to stay alert as the flood warning remains in effect. Further updates will depend on how quickly the snow melts and how much rain falls in the coming days.
