The 2017 fish surveys found bluegills to be present in good numbers. Bluegills are reaching sizes up to 8-inches with most 5-to 7-inches. Black crappies are present in fair numbers at the 7- to 9.5-inch range, with some up to 10.5-inches. White crappies are the most abundant with a large group of smaller 5.5- to 7-inch fish. The group of larger white crappies are running 8- to 10.5-inches. The largemouth bass population looks good with better than average chances at catching fish over 15 inches. A good range of sizes were surveyed from 8.5- to 20-inches. Channel catfish are available in good numbers at sizes from 15- to over 30-inches. Walleyes are present in the lake and provide an occasional catch. Surveys in 2017 only found recently stocked walleye less than 8-inches. (2017)

Water Quality

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

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information. Here is a list of current fish consumption advisories for Iowa lakes and rivers.
