Astrodym
Astrodym is a lake near the lower Karasuk River in the southern Baraba country. It lies east of Lake Studyonoye, among shallow basins in the interior between the Ob and Irtysh. The area has no direct drainage to the sea: water collects in lakes and low ground, where its extent varies with rainfall and seasonal runoff. Grassland and small woods surround the scattered waters.
