Kempir-Abad reservoir, Water reservoir at Ferghana Valley, Kyrgyzstan and Uzbekistan.

Kempir-Abad reservoir is a channel-type reservoir on the Kara Darya, where the river enters the Fergana valley near Khanabad. It is 20 km long, 6 km wide and up to 98 m deep, with a surface area of 56 km² and a volume of 1.9 km³. Its smooth grey water lies between low reddish-brown and green earthen banks, with no islands or structures in the main body.

Hydraulic engineer Ivan Alexandrov first proposed a reservoir in the Fergana Valley in 1917; the USSR Council of Ministers approved construction on 15 March 1963. Work began in 1969 and finished in 1983, flooding several thousand hectares in the Kirghiz SSR; in exchange, the Uzbek SSR transferred 4,127 hectares. A 1965 protocol between the republics covered water use from the Kara-Darya.

Kyrgyz geographer Temirkul Eshengulov links the name to the former settlement of Kampyrravat and a mineral deposit of the same name; a village called Kampyrravat stood near the present reservoir. Kyrgyzstan calls it Kempir-Abad, Uzbekistan Andijan, and both states share management 50/50 under the 2022 agreement.

Access to the reservoir can vary depending on the current political situation in the border region, so it is worth checking conditions beforehand. The warmer months offer better visiting conditions, with more stable weather and easier access to the water.

The reservoir's Kyrgyz name comes from the historic town of Kempir-Ravat, which stood on the site before flooding; Kyrgyz historian and toponymist Temirkul Eshengulov links the name to the area's old geographic and historical designation. In 2021 Kyrgyz villagers pitched yurts by the water in protest at plans to hand the site to Uzbekistan; law enforcement later removed them.
