The river contains many reservoirs which are important in the generation of hydroelectricity. The largest of these is the Toktogul Reservoir in Kyrgyzstan containing 19.9 cubic kilometres (16,100,000 acre⋅ft) of water. Dams downstream of the Toktogul in Kyrgyzstan include: Kurpsai, Tash-Kumyr, Shamaldysai and Uch-Kurgansk. Upstream of Toktogul in Kyrgyzstan is the Kambarata-2 and At-Bashi Dams while the Kambarata-1 and Kambarata-3 are in planning stages.
