Asvan

The Keban Dam is a hydroelectric dam on the Euphrates, located in the Elazığ Province of Turkey. The dam is the first and uppermost of several large-scale dams to be built on the Euphrates by Turkey. Although the Keban Dam was not originally constructed as a part of the Southeastern Anatolia Project (GAP), it is now a fully integrated component of the project, which aims to stimulate economic development in Southeastern Turkey. Construction of the dam commenced in 1966 and was completed in 1974. Keban Dam Lake, the reservoir created by Keban Dam, has a surface area of 675 square kilometres (261 sq mi) and is reputedly the fourth-largest lake in Turkey after Lake Van, Lake Tuz, and the reservoir created by the Atatürk Dam.
