Kakhovka Dam

The Kakhovka Dam was a dam on the Dnieper River (also known as Dnipro) in Kherson Oblast, Ukraine, completed in 1956 and destroyed in 2023, which provided water for the Kakhovka Hydroelectric Station (Ukrainian: Кахо́вська ГЕС імені П. С. Непорожнього, romanizedKakhovs'ka HES imeni P. S. Neporozhn'oho). The primary purposes of the dam were hydroelectric power generation, irrigation, and navigation. It was the sixth and last dam in the Dnieper reservoir cascade.

The deep water channel created by the downstream flow allowed shipping up and down river. The facility also included a winter garden. The R47 road and a railway crossed the Dnieper River on the dam.

The Kakhovka Hydroelectric Power Plant had a staff of 241 in October 2015. The director is Yaroslav Kobelya from September 2012. As of 2019, the dam was profitable bringing ₴6.1 million ($236,000) to local government budgets and ₴44.6 million ($1.73 million) to the national income.

On the morning of 6 June 2023, much of the dam was destroyed while it was under Russian control during the Russian invasion of Ukraine.

Construction of the dam began in September 1950. The last generator was commissioned in October 1956. Significant repairs and expansion were made from 2019. It is operated by Ukrhydroenergo, which was founded in 1994.

The construction of the dam flooded the Great Meadow (Velykyi Luh) forest and marsh ecosystem.

The central section of the dam consisted of (from north-west to south-east) a reinforced concrete barrage dam, the hydro power station, and a lock for shipping. The whole dam, including lengthy embankments on each side of the central section, was 3.2 km (2.0 mi) long on the side facing the reservoir. The power station had an installed capacity of 357 MW.

The Kakhovka Reservoir held 18 cubic kilometres of water, equivalent to the Great Salt Lake in the United States. The reservoir supplies water for cooling the 5.7 GW Zaporizhzhia Nuclear Power Plant, and for irrigating areas of southern Ukraine and northern Crimea via the North Crimean Canal, the Kakhovsky canal and the Dnieper–Kryvyi Rih Canal.
