The Aswan Dam is situated across the Nile River in Aswan, Egypt. The Dam was constructed between 1960 and 1970. The dam was designed by the Soviet Hydroproject Institute along with some Egyptian engineers. Workforce of 25 thousand Egyptian engineers and workers together completed this tremendous project. The Aswan High Dam is 3,830 metres long, 980 metres wide at the base, 40 metres wide at the crest and 111 metres tall. It contains 43 million cubic metres of material. At maximum, 11,000 cubic metres per second of water can pass through the dam. There are further emergency spillways for an extra 5,000 cubic metres per second and the Toshka Canal links the reservoir to the Toshka Depression. The reservoir, named Lake Nasser, is 550 km long and 35 km at its widest with a surface area of 5,250 square kilometres. It holds 111 cubic kilometres of water. The purpose of construction was to increase economic production by further regulating the annual river flooding and providing storage of water for agriculture, and later, to generate hydroelectricity. The dam has had a significant impact on the economy and culture of Egypt. The dam powers twelve generators each rated at 175 megawatts, producing a hydroelectric output of 2.1 gigawatts. Power generation began in 1967, when the dam first reached peak output it produced around half of Egypt's entire electricity production and allowed most Egyptian villages to use electricity for the first time.
