Fly Fishing the Kankakee River, Illinois: Sections, Seasons and Trip Plan
The Kankakee River flows 59 miles through Illinois, from the Indiana line past dams at Momence, Kankakee and Wilmington to the Des Plaines. IDNR calls it one of the state's best smallmouth rivers, with Momence and Kankakee River State Park the hot spots. Wade or paddle spring and fall, and respect the 12-to-18-inch protected slot below Kankakee Dam.
We'll be straight with you: no Fly Fishing Insider Podcast episode works through the Kankakee by name. The closest voice is Keith Webster of Tornado Anchors on Episode 119, published May 18, 2021, who told host Greg Keenan he spends his summers chasing smallmouth on rivers in and around Chicago. He didn't name them, so the sections below come from IDNR and Openlands' paddling maps.

Kankakee River Section by Section
Indiana Line to Momence
The upper Kankakee is lower gradient, running through the Momence wetlands and floodplain forest. IDNR's 2021 fact sheet rates largemouth good and northern pike fair near the state line, and Momence good for smallmouth. Momence is also one of IDNR's two smallmouth hot spots, with fall electrofishing catch rates of 94 to 176 an hour at Momence and the state park, and 15 to 20 an hour at 14 inches or better. Those are survey numbers, not angler catch rates.
Momence to Kankakee Dam
IDNR stocks 90,000 walleye fingerlings a year and rates Kankakee good for walleye, Aroma Park fair. IDNR says shore access and boat ramps sit in most river towns.
Kankakee Dam to Kankakee River State Park
Downstream of Kankakee the gradient picks up over bedrock and cobble. The slot water starts at Kankakee Dam. Openlands maps a 7-mile paddle from Bird Park in Kankakee to the Chippewa Boat Launch beside Warner Bridge, past limestone cliffs and islands, rated beginner to intermediate. IDNR rates Kankakee River State Park excellent for smallmouth, and the park offers eleven miles of river access.
Chippewa Launch to Wilmington Dam
Openlands' 11-mile route runs from Chippewa through the park, with an Area 9 Boat Launch on Route 113 about 2.4 miles down, to a take-out at the head of the island above Wilmington Dam. Openlands' warning in its own words: "Do not run the millrace!" IDNR rates the park reach excellent for channel catfish and good for walleye.
Below Wilmington Dam to the Des Plaines
The last miles run to the Des Plaines River confluence, where the two form the Illinois River. IDNR rates Wilmington excellent for walleye and channel catfish, and its spring walleye surveys averaged 33 an hour, mostly at Wilmington and Kankakee.
Reading the Kankakee's Flows
Live USGS gauges: Kankakee River at Momence and Kankakee River near Wilmington. USGS daily medians at Momence run about 3,430 cfs in mid-April and 780 cfs in mid-September; near Wilmington, about 7,280 cfs in mid-April and 1,060 cfs in mid-September.
IDNR warns of sharp drop-offs and deep holes for waders, and Openlands rates the park reaches beginner to intermediate depending on water levels. Our reading: wade when the gauges sit near their late-summer medians, paddle when they climb toward spring levels, and stay off when they top them.
When to Fly Fish the Kankakee River
The smallmouth peaks follow IDNR's note that early spring and fall fish best; the shading is our reading, not hatch data.

Kankakee River Rules to Know

Plan a 3-Day Kankakee River Trip
Day 1: Wade
Momence
Base in Kankakee or Bourbonnais. Wade riffles, creek mouths and fast water below the dam the way IDNR suggests, swinging a Clouser through the seams.
Day 2: Paddle
Bird Park to Chippewa
Paddle the 7-mile cliff-and-island run and get out to wade every riffle. Mind the slot: anything 12 to 18 inches goes back.
Day 3: Pick by season
State Park or Wilmington
Summer and fall: wade inside Kankakee River State Park. Early spring: fish streamers below Wilmington Dam for walleye and release every smallmouth.
What to bring: sturdy wading boots, a wading staff, a 6- or 7-weight with floating line and sink tip, a life vest and an Illinois fishing license.

Kankakee River Fly Fishing Questions, Answered
When is the best time to fly fish the Kankakee River?
IDNR says Kankakee River smallmouth fish best in early spring and fall. Spring comes with a catch: every smallmouth must be released immediately from April 1 to June 15. Fall is our pick, with lower water for wading and IDNR fall surveys of 94 to 176 smallmouth an hour at the hot spots.
Can you keep smallmouth bass on the Kankakee River?
Sometimes. From Kankakee Dam to Wilmington Dam, IDNR protects every smallmouth from 12 to under 18 inches; you may keep 3 a day, no more than 1 of them 18 inches or longer. Nothing may be kept from April 1 to June 15. Most fly anglers release them all.
Can you wade the Kankakee River?
Yes, carefully. IDNR says you can wade or fish from a canoe, but warns of sharp drop-offs and deep holes. The bedrock and cobble below Kankakee wades best at low summer and fall flows; check the USGS Momence and Wilmington gauges against their medians before you step in.
Kankakee River or Fox River: which should you fish?
IDNR rates both among the region's best smallmouth rivers. Pick the Kankakee River for clearer water, bedrock riffles and eleven miles of state park access. Pick the Fox for water closer to Chicago's western suburbs, with more dams and lower clarity. Both close to smallmouth harvest from April 1 to June 15.
