Course
The East Nishnabotna rises in western Carroll County and flows southerly past Manning and turns southwest as it briefly flows through Crawford County and into Shelby County. Immediately, it passes to the northwest of Botna, then continues another 6 miles to Irwin, then meanders southwest and passes Kirkman to the east. The river continues southerly and joins with the West Fork Nishanbotna River at Harlan, which is also the largest town on its course.
The river continues south-southwest and enters Pottawattamie County and passes Avoca, Hancock, Oakland, and Carson within the county. Entering Mills County the major tributaries join the West Nishnabotna: Farm Creek, Indian Creek, Silver Creek. The stream progresses southwesterly past Henderson and Hastings as it enters Fremont County.
