Record Low Water Levels Across the Rhine and Danube
Prolonged heatwaves have driven the Rhine and Danube to historic lows. At the Kaub gauging station on the Rhine, the navigable depth fell to 25 cm—the 2018 record—before a slight rebound. The EU’s Low-Water Information System reported that 44 % of Rhine stations and 78 % of Danube stations recorded “extremely low” levels by the end of July. In Budapest, the Danube measured 23 cm, well below the previous all-time low of 33 cm set in 2018; another source placed the level at 10 cm, indicating a discrepancy in reporting.
Background and Context
The drought intensified after the EU’s Drought Observatories noted “critical” conditions across central-western Europe in mid-July. A World Weather Attribution study linked the heightened evaporation to human-caused warming, while the Copernicus climate service linked the 2022 drought to increased wildfire activity.
Data and Statistics
- 44 % of Rhine and 78 % of Danube monitoring points flagged “extremely low” water (July 2026).
- Kaub depth 25 cm (record low).
- Danube flow in Romania ? 1,630 m³/s, roughly 1/3 of the July average.
- Hungary’s Paks nuclear plant output ? 240 MW (? 10 % of its 2 GW capacity).
- Serbia’s Djerdap 1 hydro plant operating at 20 % capacity.
- Cargo ships on the Rhine now carry only about 20 % of their normal loads, a typical vessel that would transport 2,000–2,500 t now carrying roughly 400–600 t.
On-the-Ground Reports
Volunteers in the Netherlands patrol 100 km of dikes, noting that dry peat weakens flood defenses. “Because it is so dry right now the peat loses moisture, and because of that it becomes weaker,” said Peter van Duijvendijk, a flood-defense manager. Dutch boat owner Frans Schilte observed that low-water periods have lengthened from one month to “three months.”
Official Statements & Responses
- Peter Magyar, Hungarian prime minister, announced that the Paks plant will be shut down on 1 August 2026, reducing output to 240 MW. He added that the remaining turbine could keep operating “today, and maybe tomorrow.”
- Ilie Bolojan, acting prime minister of Romania, declared a nationwide energy-sector alert and urged voluntary power cuts.
- Martin Wolters of the Rhine Waterways and Shipping Authority warned that cargo loads must be spread among more vessels to avoid damage.
- Marcel Beck, manager of western German ports, described the shipping impact as “devastating.”
Conflicting Reports & Gaps
Danube water-level figures differ: Budapest’s national water authority reported 23 cm, while an AP correspondent cited 10 cm for the same period. Cargo-capacity reductions are variously described as 20 % of normal and as a drop to roughly 400–600 t per ship. Precise forecasts for river recovery remain unavailable, and the long-term effectiveness of emergency measures such as stone-laden barges in Romania is yet to be evaluated.
What’s Next
Romanian naval forces will conduct a controlled explosion on 2 August 2026 to clear a rock obstruction and improve water flow to Cernavoda. Additional stone-laden barges are scheduled for 2 and 3 August to create a temporary dam. Hungary expects the Paks plant to operate at limited capacity until 4 August, after which a full shutdown is likely. Dutch water authorities continue to monitor dike integrity and plan seasonal “soil-sponge” measures to retain water during dry periods.
