Fishing Outlook
Bluegill
Good
Bluegill catch rates were the highest they have been in the past few years (2.22 Bluegill per 15 minutes of electrofishing in 2024). Of the Bluegill captured, 20% were considered quality-sized (>5.9 inches). Bluegill provide an excellent fishing opportunity for anglers of all ages. Anglers can catch Bluegill in the warmer months of the year using a small hook and worms, crickets, or night crawlers as bait. Fish for Bluegill along shorelines with cover, such as rip-rap, weed beds, or brush piles.
Smallmouth Bass
Very Good
Smallmouth Bass catch rates were the highest they have been in the past few years (0.49 Smallmouth Bass per 15 minutes of electrofishing in 2024). Of the Smallmouth Bass captured, 3% were considered preferred-sized (>13.8 inches), and 8% were considered quality-sized (>11 inches). Use Ned rigs, crayfish colored crankbaits, spinnerbaits, and topwater lures around wing dams, current breaks, and rocky areas to successful fish for Smallmouth Bass.
Largemouth Bass
Good
Largemouth Bass catch rates were the highest they have been in the past few years (1.21 Largemouth Bass per 15 minutes of electrofishing in 2024). Of the Largemouth Bass captured, 6% were considered preferred-sized (15 inches), and 19% were considered quality-sized (11.8 inches). Largemouth Bass prefer structure, so fish around submerged logs, weed beds, willows, or brush piles. Spinnerbaits are popular for catching Largemouth Bass on the river.

Good
Channel Catfish catch rates the highest they have been in the past few years, but still below average (0.08 Channel Catfish per 15 minutes of electrofishing in 2024). Of the Channel Catfish captured, 45% were considered quality-sized (>16 inches). Channel Catfish are often found along banks of side channel or main channel borders in log jams or fallen trees, or near wing dams. Use stink bait fished on the river bottom with a weighted sinker to successfully catch Channel Catfish.
White Crappie

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.
