This DuPage River fishing report covers a month’s worth of exploring, experimenting, and adapting on the West Branch. I’ve spent the past few weeks bouncing between old favorites and new water, chasing bass, hunting carp, and trying to make sense of the river as conditions shifted from perfect to pretty challenging. The Dupe’s accessibility and variety make it a great option, even when the water throws you a curveball.

Here’s a full breakdown of what I saw, what worked (and didn’t), and what I’m expecting as we head deeper into summer.

DuPage River Fishing Spots

One of the best things about the DuPage River is how dang accessible it is. Whether you’re a seasoned angler or just getting into it, there’s no shortage of spots to check out on the Dupe. 

The river winds through a ton of suburban park systems, and you’ll find access via parks, pull-offs, bike paths, and even mall parking lots. It’s honestly one of the most approachable rivers I’ve fished in Illinois.

Personally, my favorite way to fish the Dupe is to pick a park and just go exploring. Bounce from park to park and see what the river has to offer that day. A lot of the parks have trails that parallel the river, so it’s easy to spend an entire afternoon covering water without ever needing to move the car. 

On my last few outings, I made a point to venture into some new areas I hadn’t tried before—some hit, some didn’t. Either way, I’m glad I’m expanding my knowledge of the area.

If you’ve never fished the Dupage before, simply look on your maps, find a park, and go for it. I’m not trying to gatekeep, but part of the adventure is finding your own spots. So get out there and check them out!

Conditions

Over the past month, conditions have run the full spectrum. Early on, things were classic DuPage—clear, wadable, and easy to pick apart. Then came the June rains, and Chicagoland got dumped on. The water came up fast, clarity went out the window, and the normally tame Dupe started pushing hard. I was still able to sneak in some outings between storms, but high water and chocolate milk visibility made for a tougher read on the water.

Even with the higher flows, the river remained safe to wade in most sections, especially upstream, but it definitely paid to be cautious and pick entry points wisely.

DuPage River Bass Fishing

Bass fishing was a tale of two months. Early June saw the usual mix of spawners and post-spawners. I’d run into the occasional smallie on a bed, which I mostly left alone, but the real action came in the deeper channels and shaded banks. Overhanging trees, undercut banks, and little side runoffs were money spots. The fish weren’t fully topwater-active yet—temps weren’t quite there—but a slowly stripped streamer near structure could still draw a take.

As far as flies went, baitfish were the name of the game. I had success on Clouser Minnows and Wisco Ciscos while mixing in some fish on Clawdads slowly drifted through the deeper holes. 

Late June brought the rain, and man, did it throw a wrench in the smallie fishing. The river was high, fast, and full of weeds getting churned up. Getting a fly down and keeping it there was a nightmare. I crossed paths with a spin angler who said he was having success fishing slow wacky-rigged Senkos in deep holes, which made sense. But, I just couldn’t replicate that with a fly in those same conditions. I tried heavier flies, even split shot, but it was tough to stay in the strike zone long enough.

Even with those difficulties, I did manage a couple small fish on a popper in slower eddies—nothing to write home about size-wise, but it kept the rod bent. I’ve got a feeling the smallie bite is going to pop once the river levels stabilize and the water clears up a bit.

DuPage River Carp Fishing

Now here’s where things got fun. Carp were the MVPs of the month, hands down.

Early June had them tailing in the usual slow runs and backwater pockets, and they were eating well. Chartreuse mop flies were the go-to—ugly as hell, but the carp didn’t seem to mind. Sight fishing was fully in play as I could see the fish cruising the shallows before darting into the deeper parts to feed. 

Lessons Learned

Every time out on the DuPage reminds me that adaptability is everything. You can’t rely on just one plan. River levels shift, water temps rise or fall, and the fish move with it. Knowing when to change flies, when to shift targets, and even when to just go exploring new water has made a big difference this month.

Cutting the tail off a Gurgler isn’t something I ever thought I’d do—but when the carp are keyed in on mulberries and that’s all you’ve got that floats and kinda matches, you make it work. I’ve been tying up mulberry flies so I’m fully prepared for the next time that situation presents itself.

Heading into July, I plan on preparing more for the conditions. My guess is that the smallies will begin to look up and actively feed on the surface during the low light conditions. That paired with probably even more weeds growing in the river, I plan on honing in my topwater game.

I’ll also be more prepared for the carp fishing in the Dupage. The river is jam-packed with these rod benders and I want to be ready if they are actively feeding. Not quite sure if the mulberry bite will continue like it has been, but either way I’ll be ready for them!
