Sugar Bottom is an area around the Coralville Res, under the control of the U.S. Army Corps of Engineers, 2850 Prairie Du Chien Rd Ne, Iowa City, IA 52240-7820. You can request a map from them. There are tons of deer in the area as well as a LOT of hunting pressure. I've only hunted the Res ground two or three times, so can't offer any first hand advice. The Hawkeye Wildlife area around the Res is roughly 14,000 acres, so you should be able to find a place to hunt.
