The Big Sioux Recreational Area experienced and influx of various riverine fish species during the last major flood event that has adversely affected the overall quality of the fishery. Anglers can expect to find plenty of 5-7 inch bluegill and 6-7.5 in black crappie. The best chance an angler would have to catch quality sized fish would be to pursue channel catfish as there are plenty of fish over 15 inches with some reaching over 30. The fishing future for this resource is not expected to be great with the amount of carp, carpsuckers, buffalo and gizzard shad found during the last survey. - Last updated on 02/01/2023.
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.
