Construction

The construction of the Kayrakkum Dam for irrigation and hydroelectricity generation purposes began in the Kayrakkum steppe in July 1951. Starting in 1954, about 2,400 families or an estimated 12,000 people were resettled from some 20 villages located in the reservoir area. Most of these people were moved to the new cotton producing areas in northern Tajikistan. In 1956, the dam was completed and the filling of the reservoir began.
