# Rhine and Danube Hit Record Lows, Threatening European Shipping and Industry

Deutsche Welle reported that the Rhine's gauge at the Dutch border fell to its lowest level ever recorded, and Hungary shut down its only nuclear power plant for the first time in 44 years after the Danube fell too low to cool its reactors, as barges at the Kaub crossing run at roughly a fifth of normal cargo capacity.

The Rhine and Danube have both reached historically low water levels this summer, [Deutsche Welle](https://www.dw.com/en/what-should-europe-do-about-its-drying-rivers/a-78276662) reported, disrupting shipping and agriculture and raising concern about drinking water supplies across the region. [TASS](https://tass.ru/obschestvo/27992947) reported that the Rhine has fallen to a historic minimum, attributing the drop to reduced rainfall in recent months.

At the Kaub gauge in Germany, Deutsche Welle reported, barge clearance has dropped to levels not seen since records began in 1880, forcing commercial vessels to cut their loads by as much as 80 percent to avoid running aground. The gauge fell to 21 centimeters, and forecasters projected a further drop to 17 centimeters, according to [Bloomberg](https://www.bloomberg.com/news/articles/2026-08-04/rhine-set-for-more-disruption-after-hitting-lowest-on-record). Chemicals companies, refineries, and metals producers are among the hardest hit industries, since there is no fully viable alternative to river transport for moving coal, fuel, ore, and chemical raw materials through Germany's industrial corridor.

The drought has since spread from a shipping problem into an energy problem. Hungary shut down its only nuclear power plant, at Paks, for the first time in the facility's 44-year history after the Danube's falling water level left too little water to cool its reactors, according to [NBC News](https://www.nbcnews.com/world/europe/hungary-braces-full-shutdown-nuclear-plant-danube-river-hits-record-lo-rcna590347). The plant normally supplies roughly 40 percent of Hungary's electricity. Romania shut down two reactors at its Cernavoda nuclear plant for the same reason last month and declared a nationwide state of emergency over the resulting decline in electricity production, the same report said. In Budapest, the Danube fell to 10 centimeters, breaking a previous record low of 33 centimeters set in 2018, according to [CNN](https://www.cnn.com/2026/08/05/climate/europe-rivers-record-lows-satellite-space-rhine-danube).

The disruption arrived earlier in the season than usual, with low water already constraining shipping and power generation in early August rather than in autumn, when such conditions traditionally peak.

## What this means

Reduced barge capacity forces German manufacturers to shift toward more expensive rail and road transport or to cut production runs, a direct cost that falls on chemicals, steel, and energy companies along the Rhine corridor and ultimately on the prices of goods that depend on that supply chain. Rising freight costs on Europe's most important inland waterway add to the cost of industrial output at a moment when the region's manufacturers are already contending with high energy costs and competition from Chinese exporters.

## What to watch

- Rainfall forecasts for the Alps and central Europe over the coming weeks will determine whether river levels recover before autumn or whether the shipping disruption extends through the rest of the year.
- Announcements from German chemical and steel producers about output cuts or reroutes would show how much the water levels are already translating into lost industrial production.
