Red Rock Reservoir provides a diverse and quality fishery. The most sought after species are crappie, white bass, hybrid striped bass and channel catfish. Going into 2016 anglers should expect some excellent crappie fishing. Fall 2015 sampling showed good numbers of 10- to 14-inch black crappies. White bass fishing will remain popular during the summer as with good numbers of 12- to 16-inch fish. While targeting white bass, anglers also have the chance to hook into an occasional 2 to 15 pound hybrid striped bass. The channel catfish population is abundant at all sizes from 10- to 30-inches. Although not targeted as much in the reservoir as in the Des Moines River above and below, there is a good flathead catfish population. A decent largemouth bass fishery can be found around the rock habitat with past sampling showing fish from 9- to 20-inches. Walleyes, stocked each year, maintain a fair population of healthy fish, but are mostly an occasional catch by anglers trolling for white bass. These walleyes also create good spring fishing up the river as far as the dams in Des Moines and below the Red Rock spillway. (2015)
