An electrofishing survey was completed in spring 2018. Most largemouth bass observed were 11- to 13-inches, but large 18- to 20-inch bass were surveyed. Bluegills and black crappies were seen in good numbers, but small sizes. Bluegills were mostly 3.5- to 5-inches with a few up to 7-inches. Crappies were all 6- to 7-inches, but it is likely there are larger ones present in low numbers. Good size white bass were surveyed in the 13- to 15-inch range. Channel catfish were not captured in the electrofishing survey, but a good population exists based on angling reports.(2019)
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.
