Danube reaches historic low water, halting cruise ships and cargo

The Danube and its major tributaries are experiencing water levels unseen for decades across Central and southeastern Europe. At the Hungary‑Slovakia border in Komárom/Komárno the flow dropped to roughly 39% of the July average, while Romania reported its lowest level in 30 years. The severe drought, driven by record summer temperatures, scant rainfall and increased evaporation, has forced cruise vessels to terminate routes and transfer passengers to buses, and has left larger cargo ships anchored awaiting higher water.

Industrial activity is also hampered; a Thyssenkrupp subsidiary reduced steel output due to disrupted river transport, and grain shipments face delays. Environmental concerns include reduced oxygen in the water affecting fish and the unexpected exposure of old shipwrecks, such as a barge near Opatovac, Croatia, and Nazi‑era wrecks in Romania, raising safety worries about remaining ammunition. In Austria and Germany, navigation authorities report restricted schedules for larger cruise and freight vessels, though no formal shutdown has been imposed. Short‑term forecasts suggest a slight rise in water levels, but the long‑term outlook remains uncertain.

The situation highlights the intertwined economic, logistical and ecological impacts of climate‑induced low water on Europe’s key inland waterway.
