The Kokozek (Kazakh: Көкөзек) is a river in the Aksu City Administration and Ekibastuz City Administration, Pavlodar Region, Kazakhstan. It is long and has a catchment area of .
The river is part of the Irtysh Basin. In the spring the Kokozek is used to water local livestock.
The Kokozek has its sources roughly 10km (10miles) to the WNW of Ekibastuz city. It heads first eastwards and then bends northeastwards to the northwest of lake Karasor. In its final stretch the river meanders strongly and bends southeastwards, entering lake Shureksor from the southwest.[1] [2] [3]
The Kokozek flows across a sandy and loamy valley. Its channel is narrow and is bound by steep banks, on average not higher than 2m (07feet). The river usually flows only in the spring when the snows melt. By May it splits into separate ponds and then dries up before the summer.
