The river starts in the high Tian Shan mountains. It comes from the Tekes and Künes rivers. It drains the basin between the Tian Shan and Borohoro Mountains. The river flows into Lake Balkhash at its southeastern edge. Here, it forms a large delta. This delta is a wide area of lakes and marshes. It sits between the Saryesik-Atyrau and Taukum deserts.

The river's name has many possible meanings. Some say it comes from a Mongolian word for "open" or "clear." This might describe its wide central valley. Others think it comes from Persian words for "big river" or "murky." The water can look murky where the Künes and Tekes rivers meet. Some Uyghur scholars think the name means "hook." They say the river looks like a hook.

In the year 638, a treaty used the river as a border. This treaty divided the Western Turkic Kaganate into two states. The river was the line between the Nushibi and the Dulu.

The river is very important for water and energy. People have built many dams on its tributaries. There are dams on the Kash River and the Tekes River. The Kapchagay Hydroelectric Power Plant was built between 1965 and 1970.
