巴尔喀什湖
The river flows west-south-west from the border with China before turning north-westward south of Taldykorgan and then northward when it reaches the Saryesik-Atyrau Desert, a large sand desert south of Lake Balkhash. The river empties into Lake Balkhash near the centerpoint of its southern side. Karatal freezes up in December and stays icebound until March. Because of irrigation, the river's flow into Lake Balkash is limited.
