The Numbers Come First
The Danube River reached a water level of 23 centimeters (9 inches) in Budapest on Wednesday — shattering the previous all-time low of 33 centimeters set in 2018, according to Hungary's national water authority. The river runs through 10 countries from southwestern Germany to the Black Sea, and record-low readings are now appearing along much of its course.
No significant rain is in the forecast, and temperatures are expected to exceed 38 degrees Celsius (100°F) across the region in the coming days.
186 Tourists Evacuated, Crew Stranded
The human cost is already visible. Bulgarian police evacuated 186 tourists from the Viking Ullur, a cruise ship that ran aground near the port city of Vidin after hitting a shallow shoal that prevented it from reaching its resupply stop. Passengers ran out of food and water, according to Bulgaria's state news agency BTA. The ship's 52 crew members could remain onboard for an extended period depending on refloating options, police said.
Elsewhere in Serbia, hundreds of small boats and dozens of cargo ships were marooned on dried riverbanks near Novi Sad. Radovan Segrt, a houseboat owner who runs river excursions, told the Associated Press the water had withdrawn 'some 15 to 20 meters (50 to 65 feet) from its shore.' 'The summer season is over now, as far as boat riding is concerned,' he said.
Nuclear Output at Risk
The industrial stakes are higher still. In Romania, Danube water flow had fallen to 1,630 cubic meters per second — roughly a third of a typical July average. Authorities shut down a reactor unit at the Cernavoda power plant on Tuesday for safety reasons and announced another would follow.
In Hungary, the Paks nuclear plant — which supplies nearly half of the country's electricity — began powering down a reactor on Wednesday due to restricted cooling-water supplies, following two successive output reductions in two reactors over the previous two days.
Cargo shipping has stopped nearly entirely, according to Hungary's Ministry of Transport and Investment. Popular cruise ships that normally dock in Budapest are being forced far upriver.
The Scale of the Drought
Central Europe has been under a prolonged drought for most of the year. According to the Hungarian Meteorological Service, 90-day precipitation totals are between 80 and 130 millimeters (3.1 to 5.1 inches) below multi-year averages across nearly the entire country. Successive heat waves have accelerated evaporation and drained waterways across the region.
The exposed riverbed has also created safety hazards: Budapest authorities closed the Margaret Bridge last week after receding waters uncovered a World War II-era bomb at its base.
CEO Times Editorial Read
Europe's energy vulnerability is not a future scenario — it is today's operating reality. Two nuclear plants are curtailing output because a river ran dry, exposing how thinly margined the continent's baseload power supply truly is. That is a capital-allocation problem as much as an environmental one: decades of underinvestment in diversified cooling infrastructure and water-management systems are now extracting a measurable cost in megawatts and lost commerce.
Free-market economies price scarcity; centrally managed energy grids absorb the shock and pass it to consumers and taxpayers. The Danube's record low is a data point, not a debate — and the market for reliable European energy just got a great deal more complicated.
