Seasonal Guide for Iowa
SpringSpring Fishing
Spring blue catfish become increasingly active as water warms past 55F. They move from deep winter holes toward shallower flats and current areas to feed. In rivers, look for blues below dams and near wing dikes where current concentrates baitfish. Fresh cut shad and skipjack herring are the top baits. Pre-spawn blues feed aggressively, and this can be one of the best seasons for trophy fish.
SummerSummer Fishing
Summer is peak season for blue catfish. They are most active in their preferred temperature range of 70-85F and feed heavily. In rivers, target deep holes, outside bends, and areas with current breaks. In reservoirs, blues roam open water following schools of shad, often suspending at thermocline depth. Cut skipjack herring and large live shad are top baits. Night fishing in tailrace areas below dams can produce incredible catches.
FallFall Fishing
Fall blue catfish gorge on baitfish migrating through river systems. They become more concentrated in main river channels and below dams. This is an excellent time for trophy fish as big blues feed heavily to store energy for winter. Schools of blue cats can be located on electronics following large balls of shad. Cut bait and whole shad drifted through river channels are most effective.
WinterWinter Fishing
Contrary to popular belief, blue catfish remain active in winter and can be caught in good numbers. They concentrate in deep river holes, reservoir channels, and near warm-water discharges. Winter blue cats group tightly and once located can produce fast action. Fresh cut shad is the best bait. In tidal rivers like the James and Potomac, winter is actually considered prime trophy season as large blues concentrate in predictable areas.
