Fishing Report June 27, 2026

Upper Henry’s Fork

The Upper Henry's Fork is offering a little bit of everything right now. The Box Canyon stretch, flows and clarity have been holding beautifully and steady for a little while now, making for highly predictable and productive days. If you are floating Box Canyon, deep nymphing rigs with heavy stonefly patterns trailed by perdigons are producing consistent numbers.

Further downstream, the river is delivering some incredible technical fishing, particularly as you head into Harriman State Park. While the daytime heat can require some patience, the evening session on The Ranch has been absolutely spectacular. PMDs and small caddis emergers are drawing consistent targets during the twilight hours, and with a few leftover green and brown drakes this keeps the fish looking up. If the trout are being picky on the surface during the afternoon, don't be afraid to downsize your presentation and look toward the banks. Throwing small terrestrials like ants, beetles, or even a micro chubby is a killer way to fool some of the smartest fish in the river right now.

  Flies (Box Canyon): Size 8-10 Pat's Rubber Legs, Size 14-16 Tungsten Jig PMD, Size 16-18 Black Bullet Quill, Size 4 Sparkle Minnow, 10 Fool’s Gold Peanut Stone 

Flies (The Ranch): Size 16-18 Upright Organza PMD Spinner, Size 14 Rusty Spinner, Size 16-18 Mike’s Caddis Emerger Tan, Size 10-12 Lawson’s Extend Body Drakes, Size 16-18 Micro Chubbies in Royal

Lower Henry’s Fork

With the major spring hatches winding down, daytime action on the lower river has hit a summer transition. The bright afternoon sun and rising water temperatures mean things can feel a little cold during the middle of the day.

However, you don't want to write this section off just yet. If you pivot your schedule to earlymornings and late evenings, the river is still very much alive. The stretch from Stone Bridge down to Ashton Dam is still producing excellent results and putting some of the biggest fish of the week in the net for anglers using smart presentation.

Flies: Size 8-10 Henrys Fork Golden Stone Size 12-14, Size 14-16 Zebra Midges, Size 16-18 Olive Mic Drop, Size 4-6 Olive/White Streamers, Size Corn Fed Caddis Peacock

Teton River

The Teton is in beautiful shape right now as flows continue to drop. The river is settling into a window that is just about perfect. On any given day, Cutthroats are a plenty and eager to eat if you adapt to the section you're fishing.

In the upper meadow stretches, focus on clean presentations and matching the daily hatches. On the lower river and canyon stretches, Purple Chubbies are absolutely killing it on the surface. If you're running a dry-dropper or straight nymph rig, tie on a red or green Two Bit Hooker underneath, this combination has been good and producing well.

Flies: Size 10-12 Purple Chubbies, Size 16 Red Two Bit Hookers, Size 16 Green Two Bit Hookers, Size 18 Yellow Frenchie Jig,  Size 16-18 Hacker Stacker PMD, Hudgens Spinner, Size #4 Marabou Leech Olive

South Fork of the Snake River

If you want to play the big bug game, it is officially time to head to the South Fork. We are seeing big bugs right now, especially on the upper sections coming right out of Palisades Dam. The Salmonflies and Golden Stones are out in force, and the trout are keyed in on large profiles.

Look to hit the banks with big foam patterns, or run a heavy dry-dropper rig through the riffles. If you want to ride the wave of the most explosive surface eats of the early summer, this is where you need to be.

Flies: Size 6-8 Henrys Fork Foam Stone Salmonfly, Size 4-6 Doran’s Water Walker Pink, Size 16-18 Blowtorch Peacock, Size 14-16 Roza Pink Hare’s Ear, Size 6-8 Pats Rubber Legs, Size 4 Articulated Goldie, Size 4-6 Rusty Trombone

Madison River 

The Madison is firing on all cylinders with a mix of Salmonflies, Golden Stones, Drakes and PMDs moving up the drainage. There are bugs everywhere, but if you want the ultimate secret weapon for the Madison right now, think purple.

For whatever reason, anything with purple is absolutely hammering fish. Whether you're fishing a dry fly on the surface, trailing an attractor nymph, or swinging a streamer, make sure there is some purple in your rig before you make your first cast.

Flies: Size 12-14 Purple Haze, Size 8-12 Purple Chubby Chernobyl, Size 16-18 Dark Knight, Size 16-18 Duracell Jig, Size 4 Beldar Rubber Legs Size 4 Lil’ Kim Copper

Yellowstone National Park

The Park is offering some phenomenal surface action right now if you love hunting trout. Over on the Firehole River, the dry fly action has been excellent. The trout are looking up consistently, keeping fly rods bent thanks to steady daily hatches of PMDs and White Millers through the meadow stretches.

At the same time, the Gallatin River inside the park boundary is looking beautiful, clearing up, and coming right into its prime summer dry fly window. Anglers heading that way can expect action packed days casting Caddis, PMDs, and Yellow Sallies to eager fish along the riffles and pocket water.

Flies: Size 14 Spruce Almighty, Size 16 CDC Parachute Caddis, Size 14-16 Renegades, Size 14-16 Hackle, SIze 16-18 Red Copper John’s, Size 8-10 Henry’s Fork Golden Stone

Area Lakes (Hebgen & Henry’s Lake)

Hebgen Lake: The lake is transitioning into a classic summer routine. On calm, glassy mornings, keep your eyes peeled for the first real signs of cruising fish keyed in on Callibaetis duns and spinners. If the wind picks up, switch over to hanging chironomids or balanced leeches under an indicator along the drop-offs.

Henry’s Lake: The water is warming up, which means the fish are starting to migrate toward the cooler and deeper structures. Stripping leech patterns on intermediate sinking lines remains a top strategy. Focus on the weed lines early and late in the day, and keep in mind that stripping a White Seal Bugger or white streamer quickly through the weed beds and drop-offs is a fantastic way to trigger a strike from some of the biggest fish in the lake right now.

Flies (Hebgen): Size 14-16 Film Critic Callibaetis, Size 12 Balanced Leeches. Size 4 Articulated Goldie, Size 14-16 Cocktail Nymphs, Size 16-18 Two Bit Hookers

Flies (Henry’s): Size 14 Orange/Tan Scuds, Size 10 Rickards Seal Bugger White and Olive/Orange, Size 14-16 Cocktail Nymphs, Size 4 Articulated Goldie
