Ishim Steppe (Russian: Ишимская равнина, Kazakh: Есіл даласы, Yesil dalasy) is a plain in the southern part of Western Siberia, between the Irtysh and Tobol rivers.

The terrain is characterized by a series of crests and hollows, with the ridges extending from the northeast to the southwest.

The almost 500 kilometers (310 mi) long Kamyshlov Log (Камышловский лог), a trench where lake Bolshoy Tarangul lies, stretches roughly from east to west across the plain.

Winters are cold and long, the average January temperature ranging between −18 °C (0 °F) and −20 °C (−4 °F), reaching −48 °C (−54 °F) to −52 °C (−62 °F) in periods of severe frosts.

[4] The landscape of the plain is dominated by meadow steppes and birch forests (kolki).
