The Cahora Bassa dam is located in western Mozambique. It is one of the two main dams on the Zambezi River (the other is Kariba). It was built between 1969 and 1974, when Mozambique was still a Portuguese colony. This dam is used to convert energy from the Zambezi River into electricity by spinning turbines. That energy is then sent to cities, farms and mines in South Africa. The dam forms Lake Cahora Bassa. This dam is the largest hydroelectric plant in southern Africa and the most efficient power generation plant in Mozambique: it is 171 m (561 ft) high by 303 m (994 ft) wide at the ridge. The length of the lake is about 250 km (160 mi) and its width, 38 km (24 mi), and it floods an area of 2,700 km2 (1,000 sq mi); its average depth of 20.9 m (69 ft). The Cahora Bassa system is the largest hydroelectric scheme in Southern Africa with the power plant containing five 415 megawatt (557,000 hp) turbines.
