Fishing Forecast

Diamond Lake was drawn down and renovated in 2021. The lake was restocked in 2022 with bluegill, largemouth bass, yellow perch and northern pike. In the spring of 2024 the lake was assessed with multiple electrofishing runs, but was largely unsuccessful due to limited catch.(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.
