It serves the water supply from Almaty and after Buchtarma Reservoir one of the largest reservoirs of Kazakhstan. In a hydroelectric power plant electricity is generated.

The dam has two Absperrbauwerke, two dams, one with 470 m and 370 m length. The crown length, however, indicated elsewhere with 1900 m. The maximum height is 56 m, but alternatively also 35, called 41 and 52 m. Other characteristics of the two structures are:
