Late summer 2026 heat wave pushed the Danube and Drava to historic lows across Croatia and Serbia. On August 3, record‑low levels were recorded: the Drava fell to a new minimum three times and the Danube reached –164 cm at Bezdan, Serbia, with water temperatures around 26 °C. The drop halted most commercial navigation, imposed load limits on vessels and suspended many freight operations on both rivers. Hydro‑electric generation fell sharply, and in Hungary three of the four reactors at the Paks plant were taken offline, underscoring regional energy‑security risks. Public water‑supply operators said intake and quality remained adequate, though a safety warning was issued after an unexploded explosive device was found near Osijek. The drought also strained ecosystems and reduced river‑bank habitats. Downstream impacts were felt in Serbia, Hungary, Romania and Bulgaria, where low flows threatened transport, power generation and aquatic life. Forecasts for the next week showed no significant rise in water levels; authorities advised avoiding exposed riverbeds. Despite the low flows, household water supply stayed stable. On August 4, Prime Minister Andrej Plenković assured that Croatia’s electricity supply would remain secure, noting that the Krško nuclear plant continued operating normally.

## Claims

- Low water levels are attributed to a prolonged heat wave, lack of significant rainfall, and early snow melt. (corroborated by 6 sources)
- Low Danube levels affect energy production, transport, and ecosystems across the Danube basin. (corroborated by 6 sources)
- The Drava River in eastern Croatia recorded historic low water levels during the summer. (corroborated by 5 sources)
- Public water‑supply operators in the Danube‑Drava basin reported no current problems with water intake or quality. (corroborated by 5 sources)
- Low water levels have limited river navigation, with vessel load restrictions on the Danube and severe constraints on the Drava. (corroborated by 5 sources)
- An unexploded explosive device was discovered near Osijek as the low water exposed river‑bed objects. (corroborated by 5 sources)
- The Danube River in eastern Croatia also fell to record low water levels during the same period. (corroborated by 4 sources)
- River water temperatures rose to about 26 °C or higher. (corroborated by 4 sources)

### 2026-08-03: Record Low Danube and Drava Levels Threaten Transport, Energy and Ecosystems in the Balkans

Heat‑driven record lows on the Danube and Drava cripple navigation, cut energy output and expose hazards across Croatia and Serbia.
