District-Wide Trout Stream Fishing Report

Brook Trout - Good: Brook Trout spawn is here. Similar to Brown's, Brook Trout build nests in the stream bottom. Good insect hatches occur on warm sunny afternoons. This is a good time to try nymphs, emerger, or topwater patterns.
Brown Trout - Good: Watch the stream bottom for cleared areas in gravel. These are trout nests or redds. Avoid stepping in them. Try using larger flies or lures mimicking minnows.
Rainbow Trout - Good: Fish near bottom if no hatches occurring. Use a weighted caddis, stonefly, or mayfly nymph.
To find out if trout are coming to a lake near you, visit our website for urban pond stocking. Iowa's trout season remains open all year long. Many catchables remain in the streams challenging even the best anglers. Fish a trout stream in winter for an experience to excite all your senses. Thank you to all who participated in this year's catchable stocked trout program. Looking forward to seeing you next April.

Fishing Summary

Sampling data indicates 180 brook trout per mile with fish up to 11 inches collected. This is not an estimated population and actual trout numbers will be higher. (2012)
