Fishing Forecast

The lake was treated with rotenone in 2016 and fish were restocked that fall. Angling in 2020 was excellent. The bluegill fishery is outstanding with fish greater than 8.5 inches very abundant and many trophy size bluegills approaching 10 inches. Black crappie abundance is excellent and fish up to 13 inches are common. Largemouth bass density is extremely high, most fish are 9 to 11 inches, but larger fish up to nearly 20 inches were collected in 2020.(2020)

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.
