Fly Fishing Iowa: Driftless Trout Streams, Upper Iowa Smallmouth, Seasons and Tips
Iowa fly fishing centers on the Driftless streams of the northeast corner, where wild brown trout, stocked rainbows and some brook trout share cold spring creeks such as French Creek, Waterloo Creek and Bloody Run. The Upper Iowa River adds excellent smallmouth water, and trout anglers must pay Iowa's trout fee.
Iowa surprises people who picture nothing but corn. The northeast corner sits in the Driftless, the unglaciated pocket of bluffs and limestone springs Iowa shares with Minnesota, Wisconsin and a sliver of Illinois. The Iowa Department of Natural Resources (Iowa DNR) counts about 80 coldwater streams across ten counties, hundreds of miles in all, and more than 50 wild, self-sustaining trout fisheries.
The closest firsthand note on the Fly Fishing Insider Podcast comes from Mel Hayner, owner of The Driftless Fly Fishing Company in Preston, Minnesota, on our episode published July 18, 2023. Mel told me his guides mostly work from I-90 south to the Iowa line, that they sometimes cross it, and that Iowa has some pretty good streams of its own. The water details below come from Iowa DNR.

Where to Fly Fish in Iowa
French Creek
French Creek in Allamakee County is the one to circle. Iowa DNR lists a 5.6-mile segment where wild browns are catch and release, and artificial lures only apply in posted areas. A 2011 survey estimated 2,100 browns per mile, with fish to 20 inches. Above the West Branch confluence, a 2017 survey found about 700 browns per mile plus naturally reproducing South Pine strain brook trout, up to 11 inches. Primitive camping is allowed on the French Creek Wildlife Management Area, and some of the creek crosses private ground open to angling only.
Waterloo Creek
Waterloo Creek runs 10.5 miles in Allamakee County with wild browns throughout; a 2010 estimate put them at 685 per mile, with fish to 23 inches. Below Highway 76, all trout are catch and release on artificial lures only. Above Dorchester, Iowa DNR stocks catchable rainbows weekly from April through October. Curlyleaf pondweed is listed here, so clean your gear before moving on.
Bloody Run Creek
Bloody Run covers 6.5 miles in Clayton County, with easy access and a universally accessible site. Rainbows go in weekly from April through October, about 11,641 of them in 2025, over a wild brown population. In the posted segment upstream of the county park, browns carry a 14-inch minimum and only artificial lures are allowed. Bloody Run Park has non-electric campsites.
South Bear Creek
South Bear runs 5.2 miles in Winneshiek County near Highlandville. Iowa DNR stocks rainbows weekly from April through October and added brook trout in 2025. A 2009 sample found about 872 browns per mile, up to 16 inches. Primitive camping is allowed on the South Bear Wildlife Management Area.
Yellow River
The trout section of the Yellow River is 25 miles in Allamakee County, with wild browns, stocked rainbows and smallmouth. Public access includes Stonebrook Park, Forest Mills Road and the Volney canoe access. Iowa DNR says fishing from a canoe or kayak is the only legal way to trout fish most of this river without landowner permission, so plan a float or ask first.
Upper Iowa River Smallmouth
Iowa DNR rated Upper Iowa smallmouth as excellent in its October 2026 reports, pointing to rocky shorelines, current seams and limestone ledges. The stretch above Decorah runs 79 miles from the Minnesota line to the Lower Dam, with three dams to portage. Below it, 57 miles flow to the Mississippi with no dams; the last 8.6 miles are channelized. Above Decorah, smallmouth carry a 12-inch minimum and three a day, and they are catch and release from the Fifth Street Bridge in Decorah to the Upper Dam. In summer, Iowa DNR says to focus on the mouths of cold-water tributaries.
Mississippi River Pool 9
Pool 9 runs 31.3 miles and 35,169 acres from Lock and Dam 8 at Genoa to Lock and Dam 9 at Lynxville, both in Wisconsin, along Iowa's Allamakee County shore. Iowa DNR lists smallmouth and largemouth, with a 14-inch minimum on black bass, five a day. It gives no smallmouth rating, and I have no Iowa fly report to offer, so treat this as exploring. An Iowa license alone covers only the water between the railroad tracks on each bank, so check the boundary.
When to Go Fly Fishing in Iowa
Iowa trout streams are open all year. Treat this table as general guidance built from Iowa DNR stocking dates, seasonal notes and fishing reports, not hatch data; the shading is our judgment.

Blank cells mean not worth planning around. Browns and brook trout spawn in October and November, so stay off gravel redds. Iowa DNR suggests midday on bright, warm fall days for a sporadic hatch, with nymphs often the better bet. Its surveys show good trout numbers several days after a stocking and through winter, and the 2026 stocking calendar is on its trout page.

Iowa fly fishing questions, answered
Do you need a trout fee to fly fish in Iowa?
Yes. Iowa DNR requires a valid fishing license and the trout fee to fish for or possess trout. Listed prices are $22.00 for a resident license and $14.50 for the resident trout fee; nonresidents pay $48.00 and $17.50. Nonresidents can also buy 3-day ($20.50) or 7-day ($37.50) licenses. A fee increase was proposed for the 2027 recreation year, so check first.
When is the trout season in Iowa?
Iowa trout streams are open year-round. Iowa DNR stocks about 320,000 catchable rainbows in 45 northeast Iowa streams and three ponds from early April through the end of October in 2026. The standard limit is five trout a day and ten in possession, but several streams carry stricter rules, so read each stream's page and the posted signs.
Where can you catch wild brown trout on a fly in Iowa?
French Creek and Waterloo Creek in Allamakee County are strong starting points. Iowa DNR surveys have estimated 2,100 browns per mile on French Creek and 685 on Waterloo, though those counts are years old. Bloody Run, South Bear and the Yellow River also hold wild browns. Iowa DNR says wild streams typically run 500 to 2,000 browns per mile.
Where is the best smallmouth fly fishing in Iowa?
The Upper Iowa River is the clear pick among the waters we checked, with Iowa DNR rating smallmouth excellent above and below Decorah in October 2026. Work rocky shorelines, current seams and limestone ledges from a canoe or kayak. The Yellow River also holds smallmouth, and Mississippi River Pool 9 lists them, though Iowa DNR gives no rating for that pool.
Is Iowa really part of the Driftless?
Yes. Northeast Iowa is part of the Driftless Area, the region glaciers missed, along with parts of Minnesota, Wisconsin and Illinois. Mel Hayner explains on the podcast that its porous limestone feeds springs at about 42 degrees, which keeps streams from overheating in summer or freezing in winter. That is why trout can thrive in Iowa's northeast corner.
