Snake River Fishing Report
Week of June 20, 2026 — June 28, 2026
Current Conditions
Teton Troutfitters guides the South Park to Alpine reach. Upriver conditions shown for reference.
The upper tailwater is running at a stable 4,510 CFS directly below the dam, with total volume building to 7,070 CFS at Moose as early unregulated tributaries like Pacific Creek and the Buffalo Fork recede. Water clarity is exceptional, providing 6+ feet of visibility directly below the dam and tapering slightly to 3–4 feet near Moose. Wadeability remains highly restricted due to the powerful cold-water release, meaning safe wading is strictly limited to the shallowest gravel margins. The tailwater character is highly stable, making it the premier target for technical dry-fly and dry-dropper setups as cutthroat trout stack in the slow seams, braided channels, and protected bankside eddies to capitalize on heavy midday hatches. Conditions heavily favor floating this week.
Flows are holding around 7,070 CFS at the Moose gauge and are dropping steadily. Clarity has improved dramatically, now averaging a highly fishable 3–4 feet of visibility as Flat Creek and the Gros Ventre River recede and drop their sediment loads. Wading is highly dangerous and not recommended because of the heavy main-river volume, swift currents, and shifting gravel bars in the braids. This section represents classic Jackson Hole float fishing, with the highest trout density on the river. Cutthroats are actively holding along slow, grassy cut banks, gravel bar drop-offs, and in the soft water behind mid-river structure, responding eagerly to large attractor dry flies and heavy dry-dropper rigs. Conditions strictly favor floating.
This lower reach is running big and powerful, pushing 10,300 to 13,100+ CFS as the Hoback River and other lower tributaries enter the main stem. Clarity is fair to poor, hovering between 1 and 2 feet of visibility, but it is clearing quickly as the low-elevation snowpack is now 100% depleted. Wade fishing is completely impossible and highly hazardous. The fishing character is dominated by heavy water, meaning drift boats must work the slow, deep bankside pocket water and large, recirculating foam eddies. This section is best suited for stripping large, dark sculpin streamers or bouncing heavy double-nymph rigs deep along the inside seams. While still challenging, conditions are rapidly improving; floating is recommended for experienced rowers.
What's Hatching
Salmonfly (Giant Stonefly)
HeavyMorning through late afternoon
Staged by water temperatures reaching the 50–54°F threshold. Nymphs are migrating in massive numbers to the rocky banks to crawl out and hatch on willow branches, triggering explosive cutthroat feeding along the shorelines.
Caddis (Spotted Sedges)
Heavy2:00 PM – Dusk
Driven by peak afternoon water temperatures warming above 52°F under clear skies. Heavy afternoon emergences are occurring in the riffles, with thick egg-laying flights clustering along the banks near dusk.
Pale Morning Duns (PMDs)
Moderate10:30 AM – 2:00 PM
Triggered by late-morning water warming to 48–52°F under direct sunlight. Nymphs are drifting into slower braided seams and glide tailouts, prompting steady rising bands of cutthroat.
Blue-Wing Olives (Baetis)
Moderate10:00 AM – 1:00 PM
Triggered by cool water temperatures and overcast, humid morning skies. While tapering off on the lower river, steady Baetis hatches are still carpet-bombing the cold tailwater of Reach 1 on cooler mornings.
Yellow Sally Stoneflies
ModerateAfternoon
Triggered by afternoon water temps exceeding 52°F. These small, bright yellow stoneflies are emerging actively in cobble riffles, providing a consistent secondary dry-fly option.
What's Producing
Dry Flies
Mimics the massive stoneflies crawling the banks. Cast tight to the willows and grassy banks, adding a slight twitch.
The ultimate high-floating attractor for dry-dropper rigs, representing Salmonflies and Golden Stones.
Perfect for dead-drifting along flat, glassy seams and foam lines when selective cutthroats are rising to mayflies.
Skitter and skate through choppy riffles and pocket water during the heavy afternoon and evening caddis emergences.
Nymphs & Droppers
The ultimate heavy stonefly nymph and anchor fly to drift deep along rocky drop-offs.
A highly realistic, fast-sinking stonefly nymph. Dead-drift through fast runs as natural nymphs migrate to the banks.
A fast-sinking attractor nymph. Perfect for target-casting into fast bank pockets.
Fish as a trailing dropper behind a stonefly nymph to target trout feeding on Baetis nymphs in deep runs.
Streamers
Strip aggressively through deep, turbid pools, logjams, and off-color seams in low-light conditions.
Cast on a fast-sink tip line directly to cut banks and retrieve with sharp, erratic strips.
Emergers
Fish suspended in the surface film of slow braided seams right as the midday PMD hatch begins.
Swing through gravel bar tails and soft riffle edges in the early afternoon as caddis pupae rise to emerge.
Best Time and Section This Week
Guide's Take
The historic 2026 warm snow drought has completely rewritten the spring playbook. With the basin snowpack sitting at an unprecedented 1% of median and melted out 40 days early, our typical late-spring runoff has already come and gone. The river is dropping and clearing a full month ahead of schedule, compressed into a highly unique clearing phase. The sheer density of the early Salmonfly crawl and afternoon caddis flights is spectacular, with fine-spotted cutthroats rising eagerly in the slow, glassy eddies. This is a once-in-a-decade late June dry-fly window — get out here now.
Next Week's Outlook
Flows across the lower river will continue a steady, rapid recession as the remaining high-elevation snowpack is completely exhausted, while the Bureau of Reclamation maintains stable summer releases near 4,500 CFS from Jackson Lake Dam. The Salmonfly and Golden Stonefly hatches will reach their absolute peak next week, offering phenomenal bankside dry-fly action. Booking urgency is critical: because the runoff window was so short-lived, the prime summer dry-fly season has arrived exceptionally early, and remaining June and July guide slots are filling up immediately.
Conservation Note
Water temperatures are currently holding in a safe, productive 45°F to 52°F range, keeping native trout highly active and metabolic stress levels low. However, native fine-spotted Snake River cutthroat trout are in the final stages of their spring spawning run; anglers must strictly avoid walking on or casting to shallow, gravelly riffles (redds) to protect spawning fish and their eggs. Always practice ethical handling: squeeze your barbs, wet your hands before handling fish, and minimize air exposure by keeping them in the water.
Common Questions This Week
Is the Snake River completely blown out with runoff, or are there still float options?
No, the river is not blown out. While the lower sections below South Park are carrying some residual turbidity, the upper tailwater from Jackson Lake Dam to Moose is in beautiful, high-clarity shape with 4–6+ feet of visibility. The unprecedented 1% basin snowpack has compressed the runoff timeline, causing the river to drop and clear nearly a month earlier than normal.
What is the most effective dry-fly or nymphing setup for this week's hatches?
A heavy dry-dropper rig is incredibly productive right now. Use a highly buoyant, air-resistant dry fly like a size 6–8 Chubby Chernobyl (tan or orange) to imitate the early Salmonflies, and hang a fast-sinking size 10–12 Olsen's Straggle Stone or size 12 Olive Frenchie Jig 3–5 feet below it to target cutthroats feeding along the bankside seams.
How will the unseasonably early melt and record-low snowpack of 2026 affect summer fishing?
The record-low snowpack means the river has transitioned straight into summer conditions in late June. The advantage is world-class dry-fly fishing right now, weeks ahead of the traditional July opener. The downside is that without a deep snowpack reservoir, flows will drop rapidly by late summer — book immediately to secure dates during the optimal early summer flow window.
The Snake is clearing a full month ahead of schedule. Salmonflies are crawling, caddis are blanketing the banks, and PMDs are popping in the braids — this is a once-in-a-decade late June dry-fly window. Remaining summer guide dates are filling fast. Book now.
