Snake River Fishing Report
Week of July 5, 2026 — July 12, 2026
Current Conditions
Teton Troutfitters guides the South Park to Alpine reach. Upriver conditions shown for reference.
This upper tailwater section remains highly stable, with the Moran gauge below the dam holding steady at 4,830 CFS, driven by a controlled release of 4,970 CFS from Jackson Lake Dam. Due to the regulated flow, water clarity is exceptional with over six feet of visibility, offering a pristine tailwater environment insulated from summer freestone turbidity. Wading is highly restricted to the direct shoreline margins immediately below the dam, and downstream currents are too swift for safe foot access, meaning drift boats are highly favored. The fishing character is defined by technical dry-fly matches in slow bankside eddies and flat seams, where native fine-spotted cutthroat are looking up for early-season grasshoppers and lingering stonefly hatches.
The middle freestone section is currently flowing at a very fishable 6,640 CFS at Moose, showing a steady dropping trend as high-elevation snowmelt ends. Tributary contributions have receded significantly, with the Gros Ventre River running at 586 CFS and Flat Creek dropping to a clear 136 CFS. Water clarity has improved to an excellent four to five feet of visibility, making this braided section highly productive. Wadeability is poor and hazardous in the main channel due to deep, powerful currents, but some gravel bars are starting to offer wading opportunities in the side channels. Floating is the primary tactic, targeting slow braided seams, cut banks, and woody structure.
The lower canyon section is flowing between 7,900 CFS at South Park and 8,150 CFS near Alpine, dropping rapidly and clearing beautifully. The Hoback River has dropped to 640 CFS and the Gros Ventre is running at 718 CFS, allowing sediment to settle quickly and bringing water clarity to a highly encouraging three to four feet. Wadeability remains extremely dangerous and is not recommended on foot. The fishing character consists of fast-paced drift-boat casting in turbulent pocket water and deep canyon runs, where anglers are finding excellent reaction bites from native cutthroat and trophy brown trout by pounding the banks with large stonefly dry flies and active streamer retrieves.
What's Hatching
Golden Stonefly
Heavy11:00 AM – 3:00 PM
Water temperatures reaching the high 50s trigger a massive shoreline migration of nymphs, prompting heavy midday adult emergence along willows.
Yellow Sallies
Heavy11:00 AM – 4:00 PM
Warming afternoon water temperatures trigger consistent daily emergences, with females actively laying eggs on the water surface into the evening.
Pale Morning Duns (PMDs)
Heavy10:00 AM – 2:00 PM
Daily water temperatures crossing the 55°F threshold combined with bright midday sunlight trigger intensive PMD duns in the riffles.
Caddis (Spotted Sedges)
Moderate6:00 PM – 8:00 PM
Late afternoon cooling and fading light levels trigger intense egg-laying flights, with females skittering across flat water.
Blue-Winged Olives (Baetis)
Sporadic12:00 PM – 3:00 PM
Low barometric pressure and cloud cover during afternoon thunderstorm periods trigger localized emergences in slower braids.
Terrestrials (Hoppers, Ants)
Moderate10:00 AM – 4:00 PM
Sustained summer heat and drying bankside grasses are prompting early-season grasshoppers, ants, and beetles to tumble into the river.
What's Producing
Dry Flies
The ultimate dry-fly indicator; buoyant enough to support heavy droppers along fast seams.
Match the heavy midday golden emergence; fish tight to willow-covered banks and undercut banks.
Match the midday hatch; use for selective cutthroat rising in flat water and slow tail-outs.
Fish during the late afternoon and evening caddis return in slower bank eddies.
Cast into fast riffle seams and pockets where sallies are actively ovipositing.
Exceptional local attractor mayfly; highly visible in afternoon choppy water.
Nymphs & Droppers
The premier subsurface stonefly; suspend 3 to 5 feet under a Chubby in deep pocket water.
Sinks rapidly; an outstanding general mayfly dropper in fast current seams.
Imitates active PMD nymphs; drift through riffle transitions and head of runs.
Sleek, epoxy-coated body designed to drop immediately to the bottom in deep, heavy current.
Streamers
Cast and retrieve near deep structure and banks under low-light or early-morning conditions.
Fish on a sinking-tip line along deep canyon walls to target territorial brown trout.
Active sculpin imitation; swing through deep tail-outs and current seams.
Emergers
Highly effective during the midday hatch when trout reject fully winged adult duns.
Fish in the surface film of slow backwater braids during overcast thunderstorm windows.
Best Time and Section This Week
Guide's Take
This summer is proving to be a highly unique, once-in-a-decade season on the Snake. The complete lack of high freestone runoff means we are enjoying optimal summer dry-fly conditions weeks ahead of the traditional July schedule. Finding four to five feet of water visibility at Moose in early July is almost unheard of. The native cutthroat have had zero angling pressure for months and are rising with complete confidence to large foam attractors. The sheer volume of Golden Stones and PMDs on the water is incredible, and the fish are completely dialed into the bankside seams. It's an absolute blast out there right now — the fish are cooperative, the water is cold and clear, and we're bypassing nymph rigs to throw double-dry setups all day long.
Next Week's Outlook
The Snake River will continue to slowly recede and stabilize as the remaining high-altitude basin snowpack is fully depleted. With summer temperatures forecast to climb into the mid-to-high 80s, we expect the Golden Stonefly hatch to climb further upstream into cooler water, while terrestrial grasshopper activity will steadily intensify. Because this early clearing has compressed our peak dry-fly window, we are urging clients to book remaining open dates immediately to catch this historic, early-season action before late-summer low flows arrive.
Conservation Note
With summer air temperatures climbing into the mid-to-high 80s, keeping our native Snake River fine-spotted cutthroat trout healthy must remain our top priority. Water temperatures are currently in the safe mid-50s, but we must continue to practice proper catch-and-release ethics. Always use barbless hooks, land fish quickly to prevent exhaustion, and keep them in the water while handling them with thoroughly wet hands. Minimizing air exposure and monitoring water temperatures closely as the summer heat continues will ensure this wild fishery remains healthy for years to come.
Common Questions This Week
Is the Snake River wadeable right now, or should we plan on a float trip?
Wading remains highly restricted and dangerous across the main channels of the river due to elevated flows from controlled reservoir releases. The Moose gauge is running at 6,640 CFS, and the lower canyon is over 7,900 CFS, making river crossings hazardous. Float fishing from a drift boat is highly recommended to safely and effectively present flies to the productive bankside seams.
How will the warm weather and afternoon thunderstorm forecast affect the fishing?
The sunny weather with highs in the mid-80s is highly favorable, as it will accelerate water temperatures and drive heavy Golden Stonefly and PMD hatches. On afternoons with pop-up thunderstorm activity, the drop in barometric pressure and cloud cover will act as a major trigger for sporadic Blue-Winged Olive and PMD hatches. Be prepared to switch to smaller mayfly dries and emergers when the clouds roll in.
What is the most effective fly setup to fish right now?
The most productive setup is a dry-dropper rig. Use a highly buoyant, size 8–12 Chubby Chernobyl (tan or gold) as your dry-fly attractor and indicator, and hang a size 14–18 Perdigon or Flashback Pheasant Tail 2 to 3 feet below it. This allows you to float over the fast bankside structure while drifting a small mayfly nymph directly in front of cutthroat holding in the slower bottom seams.
Four to five feet of visibility at Moose in early July — almost unheard of. The cutthroat are completely unschooled, Golden Stones are blanketing the banks, and we're throwing double-dry setups all day. This compressed summer window won't last. Book your float now.
