Hungary drained its waters for generations. Now drought is exposing the cost
Low water levels in the Danube River are threatening nuclear energy production in Bulgaria and Romania. Bulgaria has cut nuclear plant capacity to manage cooling, while Romania is implementing emergency measures to safeguard the Cernavoda plant. In Hungary, Lake Velence has hit record-low levels, and long-term water drainage practices are compounding the effects of the current drought. The crisis has resulted in destroyed crops and disrupted river navigation, while European authorities currently lack a unified plan to address the drying river.

Danube Drought Forces Nuclear Power Cuts and Emergency Water Measures
Low water levels in the Danube River are threatening nuclear energy production in Bulgaria and Romania. Bulgaria has cut nuclear plant capacity to manage cooling, while Romania is implementing emergency measures to safeguard the Cernavoda plant. In Hungary, Lake Velence has hit record-low levels, and long-term water drainage practices are compounding the effects of the current drought. The crisis has resulted in destroyed crops and disrupted river navigation, while European authorities currently lack a unified plan to address the drying river.
Why it matters
Nuclear reactors rely on river water for cooling systems to operate safely. The Danube serves as a critical water source for multiple Eastern European nations. Prolonged drought and historical water management decisions now threaten regional energy security.
What is confirmed
- Bulgaria has reduced nuclear plant capacity due to low water levels in the Danube.
- Romania is implementing measures to boost Danube waters to cool the Cernavoda nuclear plant.
- Lake Velence in Hungary has reached record-low water levels.
- The Danube River is experiencing devastating drought affecting crops and navigation.
Still unconfirmed
- Romania sank four rock-filled barges into the Danube earlier this month to keep its nuclear reactor running.
- Hungary's history of draining waters for generations is contributing to current drought costs.
- Europe currently has no plan to address the drying of the Danube.
