Geography
Zholdybay lies off to the north of the Kokshetau Lakes and is part of the Ishim basin. Its maximum length is 6.8 km. The lakeshores are flat and gently sloping, except for the southern and eastern shores where they are rocky, rising to a height of 1.5 m to 2.5 m. Along the shore of the lake there is a wide strip of black silt smelling of hydrogen sulfide.

The Saryozek river flows into the lake from the west. The water of the lake is fresh or slightly brackish. Zholdybay freezes in early November and thaws in late April. Smaller, but more famous, Lake Kopa lies about 20 km to the ESE.
