Geographic details East Omaha sits on a flood plain west of the Missouri River. The area is the location of Carter Lake, an oxbow lake. The lake was once the site of East Omaha Island. In the crux of Carter Drive is an unnamed sulphur spring, and located south of there is Hardwood Creek. East Omaha was once the location of Florence Lake, which dried up at some point in the 1920s.
