A spring 2022 electrofishing survey sampled largemouth bass, bluegill, common carp, and rainbow trout. It is not good for the fishery that the river fish have re-established populations in Big Lake. Rainbow trout are stocked fall and winter to boost the fishing in this community fishing lake. Fishing will center around a few quality largemouth bass, channel catfish and rainbow trout.(2022)
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.
