Record low Danube levels expose WWII wrecks, fuel regional energy crisis
In the summer of 2026 the Danube River fell to historic lows across the Balkans, with water levels in Budapest recorded at just 23 cm, the lowest since 2013. The extreme drought, driven by record heat, exposed a range of submerged relics. Sunken World War II German warships, scuttled in 1944 to block the advancing Red Army, re‑emerged near the Serbian village of Prahovo, alongside a 1937 Hungarian cargo ship near Croatia. Archaeologists also uncovered a mammoth jaw, tusks and possible rib fragments in the riverbed near Ryahovo, Bulgaria. The low water has crippled navigation and forced authorities to suspend river traffic in several sections.
Energy production has been hit hard. Serbia’s Djerdap hydroelectric plants are operating at 20‑30 % of capacity, while Hungary has shut its Paks nuclear plant, which supplies about 40 % of the country’s electricity. Romania’s Cernavodă nuclear unit 1 was taken offline, and the government has asked large industrial consumers to cut usage voluntarily. Serbia’s sole oil refinery in Pancevo faces possible temporary closure, and regional governments are preparing emergency measures to avoid wider blackouts. The European Investment Bank and the EU have pledged over €30 million to fund the removal of about 21 wrecks that threaten navigation and may contain unexploded ordnance.
