Description

Pool 16 of the Upper Mississippi River contains approximately 12,000 acres of aquatic habitat, consisting of islands, side channels, and shallow backwaters throughout much of its reach. Deep off-channel aquatic habitat is limited throughout much of the pool. Unlike many pools on the Upper Mississippi River, Pool 16 does not have a wide open expanse of water in its lower reach. Exhibit caution while navigating outside the main channel in Pool 16. The lower reach (River Miles 465-457) and the base of Andalusia Island may be very shallow and large stumps are common. The confluence with the Rock River occurs in upper Pool 16 near Rock Island, Illinois. Sylvan Slough and the wing dams along the main channel provide excellent Walleye, Sauger, and White  Bass fishing. Velie Chute, a cut through in Andalusia Island, offers excellent crappie fishing. 

Access areas available for public use include: Sunset Marina (River Mile 480), Andalusia Harbor Boat Ramp (River Mile 473), Andalusia Slough (River Mile 470), and Big Branch Boat Ramp (River Mile 467). US Army Corps of Engineers navigation maps for Pool 16 are available here.

The Upper Mississippi River descends 670 miles from St. Anthony Falls, Minnesota to Alton, Illinois. A total of 29 locks with accompanying dams were constructed around the 1930s to create a waterway suitable for navigation and thus sectioned the Upper Mississippi River into ‘pools’. Illinois borders 380 miles or 13 pools of the Upper Mississippi River, from Pool 12 near Dubuque, Iowa downstream to Pool 26 near Alton, Illinois. There the river transitions to the unimpounded or ‘open’ Middle Mississippi River, descending 630 miles to the confluence with the Ohio River at the southern tip of Illinois.
