LITTLE MAQUOKETA RIVER
LITTLE MAQUOKETA RIVER. The former channel of the Little Maquoketa River lies between Sageville and Dubuque in Couler Valley. Between 1 million and 2 million years ago, the Little Maquoketa and the MISSISSIPPI RIVER eroded the land that separated them, and the Little Maquoketa changed its course flowing into the Mississippi north of the present JOHN DEERE DUBUQUE WORKS.
The Little Maquoketa is believed to have created a marsh that later became HERITAGE POND. Remains of Native Americans can be found in the area at a site called LITTLE MAQUOKETA RIVER MOUNDS PRESERVE.
