The water level at Kaub on the Rhine River is expected to drop even further, with forecasts predicting it could reach a record low of just 20 centimeters. Meanwhile, Hungary's Paks Nuclear Power Plant is operating at only about 10% capacity due to the ongoing drought, affecting three of its four units. In Budapest, the Danube River has hit a new record low of just 4 inches, prompting Romania's state water management agency to take action by sinking two rock-filled barges to create a temporary dike aimed at diverting more water to the Cernavoda Nuclear Power Plant.

(UPDATED August 6, 2026 01:15 UTC)

The water level at Kaub on the Rhine River is expected to drop even lower than the current record low of 24 centimeters, as drought conditions continue to severely impact major river routes like the Danube and Rhine across Europe. This drought, driven by exceptionally hot weather and climate change, has led to significant water scarcity in countries such as France, Germany, and Romania, forcing Serbia to reduce hydropower generation due to low water levels. In response, Romania has deployed naval forces to conduct controlled underwater explosions in the Danube River near Izvoarele village to enhance water flow toward the cooling systems of the Cernavoda Nuclear Power Plant.

(UPDATED August 5, 2026 23:51 UTC)

Water levels in Budapest have plummeted to just 4 inches, breaking the previous record low of 13 inches set in 2018. This drought has also impacted the Paks nuclear power plant, which is now operating at only about 10% capacity after low water levels forced most of its reactors offline. Meanwhile, the Danube's record low levels have uncovered the remains of dozens of World War II German battleships near the Serbian port of Prahovo, where historians note that up to 200 warships were scuttled in September 1944 to impede the Soviet advance.

(UPDATED August 5, 2026 16:12 UTC)

Romania is currently conducting controlled explosions in the Danube River to enhance water flow toward the cooling systems of the Cernavoda Nuclear Power Plant, utilizing underwater detonations to clear rocks in the river. Meanwhile, the water level at Kaub on the Rhine River is expected to drop even lower than the existing record low of 24 centimeters, which could have significant economic repercussions. Analysts predict that these low water levels may reduce German GDP by up to 0.2 percent in the third quarter, translating to an estimated loss in value added of 1 to 2 billion euros, or about $1.15 billion to $2.3 billion.

(UPDATED August 5, 2026 13:44 UTC)

The drought in Europe is causing unprecedented low water levels, severely disrupting economic activities and prompting countries to implement drastic measures. In Romania, the sole working nuclear reactor cooled by the Danube has been shut down for the first time, while the Rhine River's water level at Kaub has dropped to just 24 centimeters, the lowest since records began in 1880. The economic fallout could see Germany's GDP reduced by up to 0.2 percent in the third quarter, with river cruise operators warning that low water levels may affect their itineraries.
