A huge Soviet-era dam on the Dnipro River that separates Russian and Ukrainian forces in southern Ukraine was breached on Tuesday, unleashing floodwaters across the war zone.

Ukraine said Russia had destroyed it, while Russian officials gave conflicting accounts, some saying it was destroyed by Ukrainian shelling and others saying it collapsed due to earlier damage.


What is the dam and what happened – and what do we not know?

The Kakhovka Dam

The dam, 30 metres tall and 3.2km long, was built in 1956 on the Dnipro river as part of the Kakhovka hydroelectric power plant.

The reservoir also supplies water to the Crimean peninsula, which Russia claims to have annexed in 2014, and to the Zaporizhzhia nuclear plant, which is also under Russian control.

It holds an 18km3 reservoir – a volume about equal to the Great Salt Lake in the US state of Utah.

What happened?

Ukraine, which commented first, said Russia was responsible.

"Russian terrorists. The destruction of the Kakhovka hydroelectric power plant dam only confirms for the whole world that they must be expelled from every corner of Ukrainian land," president Volodymyr Zelenskiy wrote on the Telegram messaging app.

"The Kakhovka (reservoir) was blown up by the Russian occupying forces," the South command of Ukraine's Armed Forces said. "The scale of the destruction, the speed and volumes of water, and the likely areas of inundation are being clarified."


Some Russian-installed officials blamed Ukraine. The Russian-installed Kherson administration said Ukraine shelled the dam at around midnight Irish time, damaging the hydraulic valves.

"On Tuesday, June 6, the Ukrainian armed forces hit the Kakhovsky hydroelectric dam, as a result of which the upper part of the hydraulic structure was damaged," it said.

Other Russian-installed officials said no attack took place.

Vladimir Rogov, a Russian installed official in Zaporizhzhia, said the dam collapsed due to earlier damage and the pressure of the water.

What is the human impact?

With water levels surging higher, many thousands of people are likely to be affected. Evacuations of civilians began on both sides of the front line.

Some 22,000 people living across 14 settlements in Ukraine's southern Kherson region are at risk of flooding, Russian installed officials said. They told people to be ready to evacuate.


Ukrainian prime minister Denys Shmyhal said that up to 80 settlements were at risk of flooding.


The Russian-backed governor of Crimea said on Tuesday that there is a risk that water levels in the North Crimea Canal, which carries fresh water to the peninsula from the Dnipro river, could fall after rupture of the dam.

The Crimean peninsula is dependent for fresh water on the canal. Ukraine previously blocked water supplies to Crimea after Russia annexed the peninsula in 2014, causing water shortages in the region.

Nuclear plant

The Zaporizhzhia Nuclear Power Plant, Europe's largest, gets its cooling water from the reservoir. It is located on the southern side, now under Russian control.

The UN nuclear watchdog, the International Atomic Energy Agency, said on Twitter it was closely monitoring the situation but that there was "no immediate nuclear safety risk at (the) plant".

Russia's state nuclear energy company Rosatom said on Tuesday there was no threat to the Moscow-controlled nuclear plant.
