Snake River
A Jackson Hole and Grand Teton Snake River report built around cutthroat conservation, float logistics, verified RiverReports flow, and official USGS and NPS sources.
Check flow & weatherVerify conditions before committing.
Current USGS flow is 4,890 cfs and has been stable for about 6 hours. This is high, fast, boat-first water for the upper Wyoming page. Treat it as an experienced-float or protected-bank scout, not a casual wade call. Today's flow is near the high side of the normal seasonal range, which tops out near 5,120 cfs.
There is not enough reliable current information to recommend wading, bank fishing, or floating.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

How to fish it
Build the day around cutthroat rules, flow, and float safety.
The Wyoming Snake is a world-class cutthroat river, but useful planning starts with rules and logistics. Check Grand Teton and Wyoming regulations, the Moran flow, boat requirements, weather, and hazards before picking a dry fly.
- RiverReports has a verified Snake River at Moran page; USGS 13011000 remains the official backing source.
- Grand Teton and downstream rules are not identical, so know which reach you are fishing.
- Cutthroat handling and identification matter more than generic trout harvest language.
- Braided channels, wind, sweepers, and cold water make float planning serious.
USGS shows 4,890 cfs with a stable over about 6 hours trend. This is high, fast, boat-first water for the upper Wyoming page. Treat it as an experienced-float or protected-bank scout, not a casual wade call. Today's flow is near the high side of the normal seasonal range, which tops out near 5,120 cfs.
USGS water temperature is about 68F. Fish early and stop if handling stress is likely.
A heat alert is active near this forecast point, so the score is capped at caution until water temperature and fish-handling risk are checked. NWS alert: Heat Advisory issued August 2 at 12:35AM MDT until August 2 at 10:00PM MDT by NWS Riverton WY.
Summer: Prime dry-fly and terrestrial season when flows and temperatures cooperate.
Skip the day when the shuttle is uncertain, sweepers or braids are beyond your rowing ability, afternoon wind is building beyond safe boat control, or conservation-minded fish handling is unlikely in warm bright conditions.
Read the water
What changes the plan.
Fish when flows are stable, visibility is good, and wind is manageable. High releases, muddy tributary influence, or uncertain boat logistics should push the day toward scouting or another report.
Stable clear flow
Best for dries, dry-droppers, and bank-focused cutthroat fishing.
High release
Favor boat fishing from skilled rowers and avoid casual wading.
Cold early season
Nymph soft seams and slower water until fish look up.
Windy afternoons
Use larger dry-dropper rigs, sheltered banks, or shorter floats.
Your trip plan
Know when to go—and when to skip it.
Use the Moran trend as the trip gate. Stable clear flows with manageable wind are the best dry-fly window; higher releases, muddy tributary color, or sharp wind shifts should push the day toward a safer float, a short scout, or another river.
Skip the day when the shuttle is uncertain, sweepers or braids are beyond your rowing ability, afternoon wind is building beyond safe boat control, or conservation-minded fish handling is unlikely in warm bright conditions.
Choose the section before you rig: Moran and Jackson Lake Dam for upper flow context, Grand Teton reaches for park-rule and side-channel planning, and Jackson Hole canyon or downstream reaches only after you confirm boat ramps, takeouts, and non-park rules.
If wind, flows, or boat logistics make the Snake a poor call, pivot to the Wind River for a simpler upper-basin wade day or to the Shoshone for a different dam-influenced trout plan.
Hatches & flies
Bring a flexible box.
Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly family · report suggests “black stonefly”Black Stonefly PatternsBlack stonefly wording is a color and insect-group label, not one exact recipe. Size, nymph versus adult stage, wing profile, and weighting must remain explicit.See family guide ↗+ 3 more reviewed guides in the Fly Box
Fly family · report suggests “Stonefly nymph”Stonefly Nymph PatternsStonefly nymph patterns generally emphasize two tails, a broad thorax, segmented abdomen, and bottom contact; rubber legs, biots, beads, and jig hooks define different exact forms.See family guide ↗
Fly pattern · report suggests “Chubby Chernobyl”Chubby ChernobylIdentify the construction, not the color: a long foam overbody over a segmented dubbed underside, rubber legs at two tie-in stations, two distinct buoyant synthetic-yarn wing sections, and a short flash tail. The paired wing stations and layered foam-and-dubbing body separate the reviewed Chubby from the original Chernobyl Ant and from generic foam hoppers or beetles.See photos & how to fish it ↗
Fly family · report suggests “hopper”Grasshopper PatternsHopper patterns share a substantial body and long rear-leg impression, but foam, deer hair, wing construction, and waterline differ widely among named patterns.See family guide ↗+ 4 more reviewed guides in the Fly Box
Fly family · report suggests “BWO emerger”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide ↗
Fly family · report suggests “midge pupa”Midge Patterns by StageMidge wording can mean a threadlike larva, wing-padded pupa, film emerger, tiny adult, or visible cluster. Those profiles fish at different depths.See family guide ↗+ 3 more reviewed guides in the Fly Box Use foam dry-droppers along banks and side-channel seams when cutthroat are looking up.
Nymph slower troughs during cold or high water instead of forcing dries.
Float anglers should plan takeouts, hazards, and wind before worrying about fly changes.
Keep fish wet and handle cutthroat quickly, especially during warm afternoons.
Do not apply South Fork Idaho flow or access assumptions to the Wyoming Snake.

Common questions
Before you leave.
What should I check before fishing Snake River?+
Grand Teton rules, Wyoming Area 1 rules, boating/AIS requirements, Moran flow, weather, and river hazards
Which flow should I use for Snake River?+
Use the verified RiverReports Snake River at Moran chart for quick display and USGS 13011000 near Moran as the official source of truth.
Where should I start on Snake River?+
Start with Moran, Moose, or Grand Teton reach planning, then confirm park, state, boating, AIS, and takeout rules before launching.
Can I wade Snake River?+
Some side-channel and edge wading is possible at safe flows, but the Snake is mostly a float-first river with cold water and braided hazards.
