Bluegill numbers are fair; most fish are 4- to 7-inches. Larger crappies have not been seen since spring. Most fish this fall were 7- to 9-inches. If the bigger ones are still out there, they will be 11- to 13-inches. Largemouth bass numbers are on the rise and most fish are 10- to 17-inches. White bass numbers are moderate with most 10- to 14-inches. Walleyes and saugeyes are difficult to sample here, but there should be many smaller fish, with walleyes up to 28-inches available. Channel catfish and flathead catfish numbers are down from last winter's winter kill, but numbers are still good and most channels are 1-8 pounds and flatheads up to 40-50 pounds.(2015)

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.
