Course

The river is formed at the confluence of rivers Dulygaly-Zhylanshyk from the right and the Ulken-Zhylanshyk from the left. Both have their sources in the Ulytau range of the Kazakh Uplands. The Uly-Zhylanshyk flows roughly westwards all along its course, sometimes bending northwest for a certain distance and others to the southwest. As it reaches its last stretch the river meanders strongly. Finally it flows into the northeastern shore of Lake Aqköl, an endorheic salt lake located in Zhangeldi District, north of Shalkarteniz. Lake Katpagan is located in its basin. The Uly-Zhylanshyk is fed mainly by snow.
