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. During the summer of 2024 excessive flooding in the area allowed fish to bypass the outlet barrier and make it into the lake. Sampling is planned in 2025 to assess what effect this may have had on the lake.(2024)
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.
