Course
The Baikonyr river has its origin at the confluence of rivers Kurambai (Kuanbai) and Aktas in the southwestern slopes of the Ulytau Range. It heads roughly southwestwards within a valley having a maximum width of 2 km to the northeast of the Kalmakkyrgan. In its final stretch it flows roughly westwards, bending northwestwards to end up in the southeastern end of the Shubarteniz lake, to the south of the mouth of the Zhymyky.

The Baikonyr is fed by the winter snows. In the spring its water is fresh. But it turns salty as the flow diminishes and in the summer it dries largely up, breaking up into small pools.
