Fishing Summary

The Cedar River throughout this stretch offers excellent angling opportunities for walleye, smallmouth bass, channel catfish and northern pike. Three electrofishing surveys conducted by staff in the fall of 2025 collected a total of fifty nine walleye with 69% of those being fifteen inches or greater in length. Walleye twenty to thirty inches in length made up for 22% of the total sample with the largest measuring in at thirty one inches. Of the one hundred ninety two smallmouth bass collected 35% of those were twelve inches and larger and 16% greater than fifteen inches in length. Smallmouth bass and northern pike populations are very abundant this year in the Cedar River. There are many access points throughout this stretch of river. Navigation on this entire stretch is good for smaller flat or V-bottom boats with a smaller hp motor or canoe. - Last updated on 12/12/2025.

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.
