Vacha Reservoir (Bulgarian: Въча язовир Yazovir Vacha; before 1999: Antonivanovtsi Reservoir) is a body of water associated with a dam in Devin Municipality, south Bulgaria. It is part of the Dospat–Vacha Hydropower Cascade (500.2 MW) involving four more dams and seven power stations.[3] The three other existing dams on the Vacha River are the Krichim Dam, the Tsankov Kamak Dam and the Teshel Dam.[4]
Completed on 5 November 1975,[2][5] the Vacha Dam is situated 680 metres (2,230 ft) above sea level. The dam was designed by Bulgarian hydroengineers, though their work was overseen by Russian, Japanese and Italian experts.[2] It is a concrete gravity structure of 144.5 metres (474 ft) height, making it the tallest dam in Bulgaria together with Krichim Dam.[5] Its pumped storage power plant has a capacity of 160 MW.
