About 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.

Transit networks are well-defined, showing the paths of the Atchison Topeka and Santa Fe RR and the Burlington Northern RR connecting river towns like Alexandria and Warsaw to the interior. Moving west into Missouri and east into Illinois, the terrain is defined by drainage basins for the Wyaconda River and the three branches of the Fabius River, supporting a network of agricultural communities from Kahoka to Carthage.
