Over the last several years, volunteers, Upper Iowa University students and staff, and park and fisheries staff have installed cedar tree clusters, rock piles, and most recently pallet structures and culverts to provide more habitat diversity and cover to enhance fish populations. Volga Lake is the place to go for trophy channel catfish with fish up to 31 inches. Black Crappie numbers in the 8 inch range remain high but a few 10 inchers are out there. Bluegill 7 inches are common. A nice population of Largemouth Bass are available.(2025)
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.
