Snake River Fishing Report
Week of June 7, 2026 — June 14, 2026
Current Conditions
Teton Troutfitters guides the South Park to Alpine reach. Upriver conditions shown for reference.
The controlled release from Jackson Lake Dam is holding at a steady 2,200 CFS at Flagg Ranch, though flows build to 4,600 CFS near Moran and 8,390 CFS at Moose due to unregulated tributary inputs from Pacific Creek and the Buffalo Fork. Water clarity immediately below the dam remains exceptional with over six feet of visibility, tapering down to three to four feet as unregulated creeks enter. Wadeability is good to restricted directly below the dam, but is poor and hazardous as flows approach Moose. Staging cutthroat trout are actively holding in slower seams, back eddies, and soft water behind mid-river boulders to feed on consistent midday hatches. Conditions heavily favor floating, though technical wading remains viable near the dam.
Flows are holding around 8,390 CFS, with water clarity averaging a fair two to three feet of visibility as early snowmelt and sediment enter from Flat Creek and the Gros Ventre River. Wadeability is poor and highly dangerous due to heavy volume, swift current, and shifting gravel in the braided channels. Drift-boat anglers must focus their presentations on slow braided seams, grassy cut banks, and the calm water behind logjams where cutthroats seek refuge from the main current. Conditions strongly favor floating; wading should be entirely avoided due to safety concerns.
This lower reach is surging past 10,300 to 13,100+ CFS as the Hoback River and other low-elevation tributaries contribute massive volumes of turbid snowmelt. Water clarity is muddy and off-color, dropping below one foot of visibility. Wadeability is completely unfishable and extremely dangerous. The fishing character is dominated by fast, powerful water, restricting viable tactics to stripping large, dark sculpin streamers or bouncing heavy stonefly nymphs along the extreme inside edges and slow bank eddies where large trout seek shelter. This section is currently blown out and unfished for normal guide trips.
What's Hatching
Blue-Wing Olives (Baetis)
Heavy10:00 AM – 2:00 PM
Triggered by cool water temperatures (42°F–48°F) and low-light or overcast conditions. Tuesday's overcast, cooler weather will prompt strong coordinated emergences.
Midges (Chironomidae)
Heavy9:00 AM – 11:00 AM & Late Afternoon
Peak emergence is triggered by stable morning water temperatures (38°F–42°F) and consistent spring photoperiods. Fish key on pupae in slow tailouts and foam lines.
Caddis (Grannoms)
Moderate2:00 PM – Dusk
Triggered by late-afternoon water temperatures warming above 48°F–50°F and expanding daylight. Caddis activity is building toward the mid-June hatch.
Salmonfly (Giant Stonefly)
SporadicSubsurface Only (All Day)
Subsurface nymphs are actively migrating in high numbers toward rocky shorelines as water temperatures approach 50°F–54°F, prepping for the early June crawl. Adult emergence expected within two weeks.
Skwalla Stoneflies
LightMidday
The final stragglers of the season are active on sunny banks, but the hatch is quickly wrapping up as water temperatures rise.
What's Producing
Dry Flies
The premier dry fly for overcast BWO emergences. Fish on a long, fine 12-to-15-foot leader tapered to 5X–6X in slow seams.
Designed to target sporadic late-afternoon and evening caddis activity. Fish in the surface film along slow banks.
High buoyancy attractor. Fish close to grassy banks or use as a dry indicator to suspend heavy nymphs.
Nymphs & Droppers
A heavy stonefly nymph that serves as an excellent anchor. Bounce along the bottom in deep runs and off-color water downstream.
Sinks fast to target trout in deep slots. Perfect as a point fly in slightly turbid water.
Highly realistic early stonefly nymph. Dead-drift through deep, broken riffles and rocky runs as Salmonfly nymphs migrate.
Essential mayfly nymph imitation. Best fished on a tight-line or Euro-style rig in the clear upper tailwater.
Dominant midge pupa pattern. Sinks quickly. Dead-drift in back eddies and slow tailouts where midges naturally concentrate.
Features a slim profile and dark wing pad. Fish as a trailing dropper right before the afternoon hatch.
Streamers
Articulated sculpin imitation with a heavy head. Swing and strip aggressively along grassy cut banks and behind boulders in turbid water.
Large articulated attractor. Best used on high-volume, overcast afternoons to target aggressive brown trout.
Emergers
Deadly in the surface film on overcast days. Present drag-free to trout actively sipping just below the surface.
Slim, sparse, and highly effective nymph/emerger hybrid. Suited for the clear Dam-to-Moose section.
Best Time and Section This Week
Guide's Take
The guiding staff is experiencing a highly unique spring transition on the Snake River right now. Due to the warm snow drought compressing the season, the typical late-spring dry-fly window is condensed, meaning the clear-water tailwater of Reach 1 is providing some of the most technical and rewarding fishing of the year. The sheer density of the midday Blue-Winged Olive hatches on overcast days has been spectacular, with fine-spotted cutthroat trout rising eagerly in the slow, glassy eddies. While downstream reaches are rapidly succumbing to early snowmelt, focusing efforts on the pristine flows below Jackson Lake Dam offers anglers an exceptional opportunity to experience world-class dry-fly fishing before full runoff engulfs the entire valley.
Next Week's Outlook
Flows across the upper tailwater are projected to rise next week as the Bureau of Reclamation scales releases toward the summer peak, while downstream reaches will begin a steady recession as high-elevation snowpack is essentially depleted. Hatch activity will see a major transition, with early caddis and initial Salmonfly activity intensifying as water temperatures climb, alongside consistent midday BWO hatches on the upper tailwater. Due to the historic, early-clearing post-runoff window, there is high booking urgency for anglers to secure remaining June guide dates before the popular summer slots are fully filled.
Conservation Note
Water temperatures remain exceptionally cold, ranging from 41°F to 49°F, which keeps native trout highly active and free from heat-induced metabolic stress. However, native fine-spotted Snake River cutthroat trout are currently in their spring spawning window. Anglers must fish ethically by avoiding shallow, clean gravel beds in side channels where spawning redds are present, using barbless hooks, wetting hands before handling, and keeping trout fully submerged to ensure a safe release.
Common Questions This Week
Is the entire Snake River blown out right now, or are there still float options?
While the lower sections below Moose are taking on heavy snowmelt and running muddy with 1–2 feet of visibility, the upper tailwater from Jackson Lake Dam to Moose remains clear and highly fishable. The dam release is holding at a controlled flow, keeping Reach 1 ice-clear with over 6 feet of visibility. Anglers should focus float trips entirely on this upper reach where cutthroat are actively feeding on top.
What is the most effective dry-dropper or nymphing setup for this week's hatches?
The most consistent setup in the clear upper tailwater is a dry-dropper rig. Use a highly buoyant attractor dry like a size 10 Tan Chubby Chernobyl to support a heavy stonefly nymph like a size 12 Olsen's Straggle Stone or a fast-sinking size 12 Egan's Thread Frenchie Jig as the point fly. If cutthroat are looking up during midday BWO hatches, switch to a size 18–22 Parachute BWO with a size 22 Barr's Flashback BWO Emerger as a trailing dropper.
How will the unseasonably early melt and record-low snowpack of 2026 affect summer fishing?
The historic 2026 warm snow drought has left the basin snowpack at just 22% of median, meaning runoff has peaked weeks ahead of schedule and will be exceptionally short-lived. This translates to an incredibly early post-runoff clearing, placing the river in prime summer dry-fly form by mid-June rather than early July. However, the lack of deep snowpack reserves means flows will likely drop quickly by late summer.
Runoff has peaked and the river is already dropping — with basin snowpack at just 22%, the Snake is clearing weeks ahead of schedule. Salmonfly nymphs are staging, caddis are building, and the post-runoff dry-fly window is shaping up to arrive by mid-June. Secure your summer dates now before they're gone.
