Abstract : This profile focuses on a 93-mi reach of the Upper Mississippi River that includes Navigation Pools 11, 12, and 13. This reach extends from Dubuque, IA, and East Dubuque, WI, on the north to Clinton, IA, and Fulton, IL, on the south. It forms the eastern border of four Iowa counties and the western border of one county in Wisconsin and two in Illinois. There are 27 lock and dam systems on the upper Mississippi, extending from Lock and Dam Number 1 at Minneapolis, MN, to Number 27 at St. Louis, MO. Each lock and dam system creates a pool; thus, Pools 11 to 13 were created by the construction of Locks and Dams 11, 12, and 13. While locks and dams are numbered from north to south, river miles (RM) are numbered from the confluence of the Ohio River upstream to Minneapolis. Hence, the river miles for the Pools 11 to 13 area are numbered from RM 522.5 on the south end of Pool 13 to RM 615.1 on the north end of Pool 11. This section of the river lies within the largest continuous Federal wildlife refuge in the Midwest: the Upper Mississippi River Wildlife and Fish Refuge. The area is a portion of a large, complex river system that contains many habitat types, ranging from floodplain forest to the standing waters of backwater lakes to the running waters of side channels and the river's main channel.
