Sampling in 2025 showed Bluegills from 3- to 7-inches. The most common sizes of Largemouth Bass surveyed were 8- to 16-inches with fish up to 18-inches. Smallmouth Bass are present at low numbers for an occasional catch with fish observed from 9- to 14.5-inches. White and Black Crappies are present, but were captured in low numbers only using electrofishing gear in 2025. The crappies that were captured were good size at just over 11-inches. There were three size groups of Hybrid Striped Bass observed. They were 17.5- to 18.5-inches, 22- to 22.5-inches and 24- to 25.5-inches. Ada Hayden has a quality Channel Catfish population with sizes previously surveyed from 10- to 23-inches. A unique trout fishery exists as fall and winter stocked Rainbow Trout are surviving and growing year round. Trout are most often caught in the spring, fall and winter when water temperatures are below 70 degrees. Other species present in lower numbers that can provide the occasional catch include Walleye and Yellow perch. - Last updated on 01/02/2026.
In nearly all cases, Iowa fish are safe to eat. Cleaning and/or preparing the meal causes most of the problems regarding taste or color of fish. Like all living creatures, fish are susceptible to diseases, parasites, and other naturally occurring conditions in the water. If you suspect your fish is affected by any of these conditions, do not eat it. Consider eating smaller and younger fish which usually have lower levels of contaminants than larger ones. Most contaminants accumulate in larger, older fish. For additional information, check out our resources for eating and cooking Iowa caught fish.
