Here it merges with the Kara Darya (near Namangan) to form the Syr Darya. It is 807 kilometres (501 mi) long (together with its upper course Chong-Naryn) and its basin area is 59,100 square kilometres (22,800 sq mi). It has an annual flow of 13.7 cubic kilometres (11,100,000 acre⋅ft).

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: Kürpsay, Tash-Kömür, Shamaldy-Say and Üch-Korgon. Upstream of Toktogul in Kyrgyzstan is the Kambar-Ata-2 and At-Bashy Dams while the Kambar-Ata-1 Dam is in planning stages.
