Lake Sharbakty lies 5km (03miles) to the north, Tuz 22km (14miles) to the east and Tengizsor 23km (14miles) to the southeast. River Irtysh flows 16km (10miles) to the southwest. The M38 Highway from the Border of Russia to Pavlodar and Semey (Semipalatinsk), passes 6.5km (04miles) to the northeast of the eastern end of the lake.[3]
The lake has an oval shape roughly oriented in an east–west direction. It doesn't dry out in the summer and always freezes in the winter. Unlike the other lakes in the area, Uyaly's waters are only slightly saline, with a low mineralization of 27g/l, carbonate and bicarbonate being the predominant ions. The pH of the waters is 9.5 and among the lakes of the region only lake Borli further north has an almost as high alkalinity.[2] [1] [4]
Lake Uyaly is surrounded by steppe vegetation.[4]
