As Iowa's master waterway, the Des Moines River rises beyond the extreme northwest corner of our State, and flows entirely across it to the southeast corner. The name is the oldest term applied by Europeans to any feature of the territory. As such the title is derived from the Moingona Indians whom Jolliet and Marquette, commonly ascribed discoverers of the Mississippi, found in the summer of 1673 located near the river's mouth.
