Geography

edit

Ulken Koskol is an endorheic lake in the Kazakh Uplands. It is part of the Ishim River basin. The bottom is flat and the lakeshore clayey and gently sloping, [4] Ulken Koskol is located in an area where there are numerous lakes. Kishi Koskol lies 4.5 kilometers (2.8 mi) to the SSE, Shalkar 15 kilometers (9.3 mi) to the south and lake Saumalkol 13 kilometers (8.1 mi) to the southwest. River Kamysakty has its sources a little to the NW of the northern end of Ulken Koskol.[1]

The lake is fed mainly by snow and precipitation. Since the water is salty and has high mineral content it is not suitable for drinking. Ulken Koskol is largely surrounded by agricultural fields.[3][4]

Flora

edit

Sedges and fescue grow in the fields nearby that are not plowed.[4]
