Geography


Karasor is an endorheic lake in the central Kazakh Uplands. It stretches from east to west to the north of the Karkaraly Range and to the south of the Ayr Mountains. It is the largest of the lakes at the bottom of a vast depression. Smaller lake Katynkol is located to the SW of the southern end, Saumalkol to the west, and Balyktykol 20 kilometers (12 mi) to the east. The shape of Karasor is sinuous, narrower in its central section. The bottom of the lake is mostly silt, with a smell of hydrogen sulfide. The lakeshores are generally clayey or pebbly, low and gently sloping, but in certain spots they are rocky, with cliffs reaching a height of 25 meters (82 ft). There are two little islands on the lake, Zhumyrtkaly and Araltabe.[1]

Fourteen small rivers flow into Karasor, including the Karkaralinka, Karsakpai, Taldy, Karasu, Yesenaman, Barak and Kemer. All of them dry up in the summer. The lake freezes in November and thaws in late April or early May.[5] During periods of drought the shallow eastern part of the lake may dry up, turning into a salt pan.[1]
