Fishing Forecast

The lake is planned to be renovated starting after Memorial Day. The lake will be drawn down, shorelines deepened and rocked, the bottom dredged, fish habitat placed, and fish eliminated and eventually restocked at the completion of the project. The presence of yellow bass and abundance of common carp are the reason for removing fish. Anglers will still have the upcoming spring to fish. Bluegill numbers are moderate with many 6- to 8-inch fish. Crappie numbers are good with most 8- to 9-inches. Largemouth bass numbers are fair and most are 11- to 14-inches.(2015)

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.
