Geography
Kalatuz is part of the Irtysh basin. It lies in a tectonic depression of the Kulunda Plain close to the Irtysh, only 4 km northeast from its channel. It is located about 46 km to the SSW of lake Maraldy and 30 km to the WNW of lake Borly.

The shores are mostly sloping and on the northern and southern sides there are sections with up to 6 m high cliffs. Several small rivulets flow into the lake, but there is no outflow. The lake does not freeze in winter owing to high salinity.
