USGS Topo · Published 1989About this map
The Mississippi River and Des Moines River converge in this mid-1980s look at the tri-state border region of Iowa, Missouri, and Illinois. At the heart of this landscape lies Keokuk, where the massive Keokuk Dam spans the water to Hamilton, Illinois. The map captures the sophisticated river management system of the era, including Lock and Dam No 20 and the numerous islands and sloughs such as Long Island and Fenway Island.
