Brook Trout - Slow: Brook trout in pre-spawn condition and more interested in spawning than feeding making catching more difficult. Dabbling a fly through narrow vegetated runs or find a deeper pool above a beaver dam may grab a brooks attention.
Brown Trout - Fair: Avoid walking in cleared gravel areas in faster moving water. These are trout nests or redds. Brown trout spawning activity nearing an end. Try using flies imitating minnows or other small fish.
Rainbow Trout - Good: Even though catchable stocking is completed for the season, plenty of fish remain in the stream to confound anglers. A small chunk of worm or cheese under a bobber fished through a deeper hole may turn a rainbow head. Cut line on deeply hooked fish if returning to water.
As of November 1, trout stream stocking is finished for the year. Staff would like to thank all our trout anglers and supporters for making this season fun and rewarding. Fall community pond stocking in full swing. Visit our website to find out more. Many trout streams flow through public areas where hunting occurs.

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.
