Fishing Forecast

The fishery in Greenfield Lake will again provide good fishing in 2025. The fisheries survey from 2024 indicates good numbers of largemouth bass from 12 to 15 inches. The bluegill population lacks quality with only 6% of the sampled fish being over 6 inches. The black crappie population is low to moderately abundant with the dominate size 9-inches. Greenfield Lake is a good catfishing lake with excellent numbers of fish 14 to 24-inches. Walleyes stocked annually by Adair County add to this fishery. Yellow bullheads (10 to 13-inches) round out the fishery. A walking path circles the lake and provides great shore line access for fishing. Being a water supply reservoir boats are restricted to electric motor only.(2024)

Consumption Guidelines

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases

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.
