The blowing up of the Kakhovka HPP: an environmental disaster

The destruction of the Kakhovka hydroelectric power station became one of the largest man-made and ecological disasters related to Russia's war against Ukraine. The breach of the dam on the Dnieper led to the flooding of vast territories, loss of life, a humanitarian crisis, and long-term damage to the environment. Below is a factual analysis of the event and its consequences.

What happened on June 6, 2023

The Kakhovka Hydroelectric Power Station was located in the lower reaches of the Dnieper River and held one of the largest reservoirs in Ukraine. Early in the morning on June 6, 2023, the dam was destroyed. At that time, the station and the surrounding area were under the control of Russian troops.

The destruction of the dam led to an uncontrolled release of a huge volume of water from the reservoir downstream, which caused a catastrophic flood.

Scale of flooding

Water rapidly flooded settlements located downstream of the Dnieper, on both banks of the river.

• Residential houses, streets, and infrastructure facilities were submerged; residents had to be urgently evacuated.
• People and a large number of animals—both domestic and wild—died.
• Water supply systems were destroyed and agricultural lands were damaged.

UN structures and humanitarian organizations recorded the consequences of the flood and provided assistance to the affected, noting that access to some flooded areas was difficult.

Environmental damage

In addition to the immediate flooding, the disaster dealt a heavy blow to the ecosystem of the lower Dnieper and the Black Sea.

• Oil products, chemicals, and the contents of flooded economic facilities have entered the water.
• Protected areas, habitats for birds and fish, and spawning grounds have been affected.
• The release of the reservoir has exposed the bottom and disrupted the established water balance of the region.

Ecologists assess the consequences as long-term: the restoration of ecosystems and the impact on agriculture will be felt for many years.

Threat to water supply and the Zaporizhzhia Nuclear Power Plant

The Kakhovka reservoir played a key role in supplying water to the southern regions, irrigating agricultural lands, and providing cooling for the Zaporizhzhia nuclear power plant.

• The sharp drop in water levels in the reservoir has created problems with drinking and technical water supply for settlements and irrigation systems.
• IAEA monitored the situation with water intake for the needs of the Zaporizhzhia NPP, as the plant used water from the reservoir for cooling.
• The agency reported on the measures taken to ensure the cooling of the station using alternative sources.

The significance of the disaster

The destruction of the Kakhovka Hydroelectric Power Station demonstrated how military actions and the aggressor's control over critical infrastructure create catastrophic risks for the civilian population and the environment. The event became part of the overall picture of the consequences of Russia's aggression against Ukraine, condemned by the UN General Assembly in resolution ES-11/1, adopted by 141 votes in favor.

The long-term environmental and humanitarian consequences of the flooding serve as a stark reminder that the cost of this war extends far beyond the front lines.

Frequently Asked Questions

When was the Kakhovka Hydroelectric Power Station destroyed?
The dam was destroyed early in the morning on June 6, 2023. At that time, the station and the surrounding area were under the control of Russian troops.

What were the consequences of the flooding?
The dam breach caused widespread flooding of settlements downstream of the Dnieper, loss of life and animals, destruction of housing and infrastructure, as well as severe environmental damage.

How did the disaster affect the Zaporizhzhia Nuclear Power Plant?
The Kakhovka Reservoir was used for cooling the Zaporizhzhia Nuclear Power Plant. The sharp drop in water level created risks for water intake, and the IAEA monitored the situation, reporting on measures to ensure the cooling of the plant using alternative sources.

What is the ecological damage?
Oil products and chemicals entered the water, protected areas, bird and fish habitats were affected, and the water balance of the region was disrupted. Ecologists assess the consequences as long-term.
