Enjoy the vibrant scenery and cool weather this fall fishing for Iowa’s prize trout in northeast Iowa’s hundreds of miles of trout streams. From easily accessible streams in state or county parks, to those found in Iowa’s most wild and remote natural spaces, there are plenty of places to catch rainbow, brown and brook trout.
“It’s a busy place this time of year,” said Mike Steuck, Iowa DNR fisheries supervisor for interior streams. “A lot of wild fish are in these streams for anglers to test their skills.”
View some of the best fall colors in the narrow valley of Little Paint, west of Harpers Ferry. Look for trout behind larger boulders and under rock ledges. Let your lure or bait drift around the boulders and just in front of the ledges.
Catch stream-reared brown trout up to 16 inches and 10-12 inch stocked rainbow trout in the Maquoketa River. Miles of public access spots line the river in Clayton and Delaware counties. Find rainbow trout in pools and runs while brown trout will be near wood habitat.
The best opportunity to catch all three trout species in a single trip is at Spring Branch Creek, southeast of Manchester. There is great public access to more than 1.5 miles of coldwater stream.
Learn to “read” a stream, to identify habitats that offer food and cover. Trout are not randomly scattered in a stream. They locate themselves along the edge of the current flow near protective cover. The stream current carries food to the trout while it waits.
Trout try to bulk up in the fall for winter and seem to always be hungry. Brown and brook trout lay their eggs in nests called redds during October and November. The eggs remain in these areas of cleaned gravel on the stream bottom until they hatch in late winter or early spring. Be careful where you walk to avoid stepping in or directly above these nests.
“Brown trout are wary, be as quiet and hidden as you can,” said Steuck. “If you can see them, they have already seen you and probably will not bite.”
Fish overcast and gray days when using spin fishing gear. Trout seem to be less wary of lures at this time. If fly fishing, target midday on sunny and bright days. In cooler fall temperatures, bright warm days can stimulate an insect hatch. Dry flies can still be productive, but the insect hatches become more sporadic and less intense than in the summer.
Early fall is grasshopper time, especially for brown trout. Gather them in the cool of the early morning. Imitation grasshoppers also work well along with night crawlers, particularly following light rainfall.
Iowa’s trout season is open all year. Iowa’s trout streams are too. About 105 coldwater trout streams await anglers in 10 northeast Iowa counties. DNR fisheries staff stock trout in 50 streams weekly through October. All October stockings are unannounced.
Anglers need to have a valid fishing license and pay the trout fee to fish for or possess trout. The daily limit is five trout per licensed angler with a possession limit of 10.
