Record Low Danube and Drava Levels Threaten Transport, Energy and Ecosystems in the Balkans FAST-MOVING
A prolonged heat wave, scarce rainfall and early snow melt have driven the Danube and Drava rivers in eastern Croatia and Serbia to historic lows. Monitoring stations recorded the lowest water levels since measurements began, with the Drava hitting a record low three times over a short period and the Danube falling to a historic minus 164 cm at Bezdan in Serbia. The drop has severely limited commercial navigation, restricting vessel loads on both rivers, and has forced the suspension of many freight operations.
Public water‑supply operators in the Danube‑Drava basin say they are currently able to meet demand and maintain water quality, but the exposed riverbeds have revealed hidden hazards, including an unexploded explosive device near Osijek. Water temperatures have risen to about 26 °C, adding stress to aquatic ecosystems. The low water also curtails hydro‑electric generation and, in Hungary, has taken three of four nuclear reactors offline, highlighting the broader energy‑security implications across the region.
