Sarykopa (Kazakh: Сарықопа; Russian: Сарыкопа) is a bittern salt lake in the Kostanay Region, Kazakhstan.

[1] Sarykopa lies in the steppe of the central sector of the Turgay Basin in Zhangeldi District, in the southern area of Kostanay Region.

The 164 kilometers (102 mi) long Saryozen river flows into the lake from the north and the Teke from the west.

Since the lake is fed by snow its level is subject to variations according to the inflow, reaching a maximum area of 336 square kilometers (130 sq mi) in the spring floods when the snows melt.

[6][2] Sarykopa is a refuge for birds such as the white-tailed lapwing, steppe gull, slender-billed curlew and the great white pelican, as well as the critically endangered siberian crane,[5] but the effects of human action on the lake are unfavorable for wildlife.
