Abstract
The flow of the Ile River is regulated by a cascade of reservoirs on the tributaries and along the river trunk: Bartogay ( Shelek River ), Kapshagay (Ile River), etc. The maximum flow rates along the Ile River are determined by the capa of the discharge structures of the hydroelectric power plants and the unregulated flow of the lateral inflow (Kaskelen River, etc.). The Ile River is formed by the confluence of the Tekes and Kunges Rivers, and it also receives a lot of tributaries, the sources of which flow down from the snowy peaks of the adjacent mountains. In terms of water content and turbidity, the water of the Ile River ranks third among the large rivers of Central Asia (Amu Darya, Syr Darya), and is only slightly inferior in water content to the Syr Darya River.
