The Keban Dam is a combined rockfill and concrete gravity hydroelectric dam operated by the State Hydraulic Works (DSİ). The dam is 1,097 metres (3,599 ft) long and its crest is 207 metres (679 ft) above the level of the river-bed (848 metres (2,782 ft) above sea-level). Its eight water turbines are capable of producing 1,330 MW. The storage capacity of Lake Keban is 30.6 cubic kilometres (7.3 cu mi) and the surface area of the lake is 675 square kilometres (261 sq mi), although the lake has reportedly reached higher levels in the past. Due to Lake Keban's relatively high elevation at 845 metres (2,772 ft) above sea-level and its location in an area with high precipitation, evaporation is relatively low at 0.48 cubic kilometres (0.12 cu mi) per year compared to reservoirs in Syria or Iraq. Apart from the Euphrates Valley directly upstream of the dam, the lake has also flooded parts of valleys of the Murat River and the Karasu, the two rivers from which the Euphrates emerges. Although the dam was not originally intended for irrigation, 63,872 hectares (157,830 acres) of agricultural land was irrigated from Lake Keban in 1999.
