Angling opportunities on Pools 20-26 of the Upper Mississippi River are as diverse as the habitats created by both man and nature. The upper portion of a pool typically resembles pre-impoundment conditions, with swifter current, deeper side channels, and relatively few connected backwaters. The lower portion of a pool becomes more like an impoundment with some current, shallower side channels, and connected backwaters. Channel catfish can be found throughout the pools near woody drift piles, wing dikes, natural shorelines, sand bars, and rock protected banks. They can be caught on a variety of natural or prepared baits, depending on the season. Flathead catfish, another popular species, are typically found near woody cover or rock structures. Flathead catfish clearly prefer live bait. Because flathead catfish are generally active at night, most are caught on trotlines baited with live sunfish. Small flathead catfish are very abundant, but good numbers of fish over five pounds are present too. Blue catfish are also found in the Upper Mississippi River, but are less abundant than other catfish species, especially in the most upstream pools. Best locations to catch blue catfish include deep holes, in the main channel, and especially in lock and dam tailwaters, and around rock structures. Favored baits include cut shad or herring and shrimp. Although uncommon, some blues may exceed 70 pounds.
Sauger and walleye prefer a hard, rocky river bottom and are usually found near wing dikes or riprap shorelines during warm months. They concentrate in deeper water during the winter, usually near dam tailwaters. Cool temperatures with minimal flow through the navigation dams are the best conditions for fishing success. The best technique for catching walleye and sauger near tailwaters is to fish a heavy jig, possibly tipped with a live minnow, near the bottom. Slack water areas associated with wing dikes, tributaries, and backwaters are home to largemouth bass, bluegill, and crappie. Freshwater drum, the most common fish caught by anglers, can be found in almost any habitat and caught on a wide variety of artificial and natural baits.
Lake sturgeon, a Missouri protected species, are occasionally caught by anglers as a result of the lake sturgeon reintroduction program. Some of these fish exceed 40 pounds and are exciting to catch; however, all lake sturgeon must be released immediately. Anglers should use caution when boating in slack water areas of the Mississippi River. Bighead carp and silver carp, which are invasive species, are abundant and have a tendency to jump in front of and into moving boats, so anglers are urged to be cautious. To slow the spread of invasive species like zebra mussels, all anglers should carefully inspect and wash their boats and trailers with hot water, and drain and disinfect live wells before moving to another stream or lake.
