Fly Fishing French Creek, Iowa: Sections, Seasons and Trip Plan
French Creek is a small, spring-fed trout stream in Allamakee County, northeast Iowa, flowing through the French Creek Wildlife Management Area. Iowa DNR lists 5.6 miles of water with wild brown trout that are catch and release only, plus wild brook trout in the headwaters. It is open all year, and it is walk-and-wade fishing.
No Fly Fishing Insider Podcast episode covers French Creek yet, so the facts below come from Iowa DNR and the U.S. Fish and Wildlife Service. The closest voice in our archive is Mel Hayner, owner of The Driftless Fly Fishing Company in Preston, Minnesota, who told me Iowa has some pretty good streams of its own.
Why it matters: Iowa DNR's 2011 survey estimated 2,100 wild browns per mile, with fish to 20 inches, in a creek you can cast across. Iowa DNR also calls it challenging, with crystal clear water and aquatic plants along the edges. Big numbers, spooky fish.
Species
Wild brown trout throughout; wild South Pine strain brook trout in the headwaters and West Branch
Best months
Open all year; spring and fall are our pick, winter works on spring-fed water
Character
Small, clear Driftless spring creek with weedy edges; wade only
Nearest towns
Waukon and Lansing in Allamakee County; Decorah for a bigger base
Nearest airports
La Crosse Regional (LSE), Rochester, Minnesota (RST); Cedar Rapids (CID) farther south
Rule to know
Brown trout are catch and release only; check Iowa DNR rules
French Creek Section by Section
Segment names, lengths and survey numbers come from the Iowa DNR stream pages for French Creek, the West Branch and the French Creek Road tributary. Survey counts are years old. All of it is wade fishing.
Zone 1: Upper French Creek and the West Branch (Brook Trout Water)
Boundaries: French Creek upstream of the West Branch confluence, plus the 0.4-mile West Branch itself.
Access: Iowa DNR describes the West Branch as a very secluded small stream reached by a 1-mile walk from the parking lot on the wildlife area.
Best for: wild brook trout. A 2017 survey above the confluence found about 220 brook trout per mile to 11 inches and 700 browns per mile to 16 inches. The West Branch held 216 brookies and 744 browns per mile in 2011. In 2007 the National Fish Habitat Board named the West Branch one of its "10 Waters to Watch," and the U.S. Fish and Wildlife Service called it one of only four Iowa streams with consistent wild brook trout reproduction.
Zone 2: The French Creek Road Tributary
Boundaries: a 0.4-mile spring creek on public land that joins French Creek on the wildlife area.
Access: public ground on the French Creek Wildlife Management Area.
Best for: small brook trout; Iowa DNR last stocked brookies here in June 2025.
Zone 3: The Main Stem Below the West Branch
Boundaries: from the West Branch confluence downstream through the wildlife area valley, which Iowa DNR places south of the Upper Iowa River.
Access: public wildlife area land, plus stretches on private property where Iowa DNR says only angling is permitted. Respect the posted signs.
Best for: numbers and size of wild browns. This is the 2,100-per-mile water, and the fish see you coming.
Gauge: French Creek has no real-time USGS gauge. The closest is USGS 05388250, Upper Iowa River near Dorchester, IA, on the main river upstream of the French Creek valley.
Reading the flows: our reading, not agency guidance. Use the Dorchester gauge only as a rain signal: a sharp jump means runoff across the watershed, and a small spring creek can run off-color for a day or two. When the gauge is flat, French Creek is usually fishable.
When to Fly Fish French Creek
Our reading of Iowa DNR's survey, stocking and seasonal notes; not hatch data, and the shading is our judgment.
| Target | JAN | FEB | MAR | APR | MAY | JUN | JUL | AUG | SEP | OCT | NOV | DEC |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Wild browns, nymphs | ||||||||||||
| Small dries and midges | ||||||||||||

| Headwater brook trout |
LightModerateHeavy
Browns and brook trout spawn in October and November, so watch for gravel redds and stay off them. Iowa DNR suggests midday on bright, warm fall days for a sporadic hatch, with nymphs often the better bet. In midsummer, fish hoppers and ants tight to the weedy edges.

Plan a 3-Day French Creek Trip
Day 1: The Main Stem
Fish the public water below the West Branch. Move slowly upstream, look before you cast, and fish nymphs and scuds along the weed edges.
Day 2: Walk In for Brook Trout
Hike the mile to the West Branch for wild brook trout: short casts and a careful approach. Finish on the French Creek Road tributary.
Day 3: Your Pick
Repeat your best water, or try another stream from our Iowa guide: Waterloo Creek for more wild browns, or the Yellow River for a float.
Base: Waukon or Lansing to stay close, or Decorah for more lodging and food; Iowa DNR allows primitive camping on the French Creek Wildlife Management Area. Bring: a 7- to 8-foot 3- or 4-weight, leaders of 9 feet or more with 5X and 6X tippet (our setup for clear, weedy spring creeks), light wading gear and a stream thermometer.

French Creek Fly Fishing Questions, Answered
When is the best time to fly fish French Creek?
French Creek is open all year, and spring and fall are the best bets in our reading. March through May beats the summer weed growth; September and October give the best shot at a big brown before the spawn. Summer is hopper and ant season.
Can you keep trout on French Creek?
Brown trout on French Creek are catch and release only, and artificial lures are required in posted areas, according to Iowa DNR. Brook trout fall under Iowa's combined trout limit of 5 a day and 10 in possession, though the wild headwater brookies are worth putting back.
Is French Creek hard to fish?
Yes, French Creek is a technical stream. Iowa DNR calls the fishing challenging because of crystal clear water and lots of aquatic plants along the edges. Approach from downstream, keep low, use long leaders and fine tippet, and expect refusals.
French Creek or Waterloo Creek: which should you fish?
Both are Allamakee County wild brown trout streams. Iowa DNR's last French Creek survey estimated about 2,100 browns per mile against 685 on Waterloo Creek, which holds bigger fish, to 23 inches, and stocked rainbows above Dorchester. French Creek is smaller and adds wild brook trout.
