Red Rock Reservoir provides a diverse and quality fishery. The most sought after species include 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 large black crappies in the 10 to 14 inch range. White bass fishing will remain popular during the summer months as there are good numbers of fish in the 12 to 16 inch range. While targeting white bass anglers also have the chance of hooking into an occasional 2 to 15lb 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 that are stocked annually maintain a fair population of healthy fish, but seem to mostly be an occasional catch by anglers trolling for white bass. These walleyes also create some good spring fishing up the river as far as the dams in Des Moines and below the Red Rock spillway. (2015)

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed.
