History

The Racoon River was first documented on the 1814 map by Lewis and Clark, though the USGS references the name to a later map from 1843 named ''Hydrological Basin of the Upper Mississippi River'' based on field measurements by Joseph N. Nicollet during his Midwestern expeditions in the 1830s.
