Балхаш
The river flows north from the border with China before turning north-westward north of Sarkand and then west before turning north northward when it reaches the Saryesik-Atyrau Desert, a large sand desert south of Lake Balkhash. The river empties into Lake Balkhash just east of the Aksu River on its southern side. Lepsy freezes up in December and stays icebound until March. Because of the amount of water taken for irrigation, the river's flow into Lake Balkash is limited.
