The nearest inhabited places are Petukhi, close to the southern shore, and Makarovka, near the northwestern end.

[5][1] Located in the Kulunda Plain, Petukhovo has an irregular shape, stretching roughly from northwest to southeast for approximately 7 kilometers (4.3 mi).

Silt deposits at the bottom of the lake reach a thickness of 2 meters (6 ft 7 in) in the central part.

The minerals in the bottom sediments are dominated by terrigenous quartz, feldspars, excess-Ca dolomite, and Mg-calcite, with the proportion of carbonates increasing in the lower part of the section.

[1][3] The lake is surrounded by deforested steppe landscape of low hills.
