Teton River
Driggs to Teton Canyon
E Idaho, USA
Open live forecast →Target species: Cutthroat and Rainbow.
Stream gauge: 13057940. Flow and water temperature update on every refresh.
Weekly AI Outlook as of 06/05/26
The Teton is running at a fishable 38 cfs — well below typical June flows but offering excellent wadeable conditions. This low, clear water has cutthroat and rainbows keyed into PMDs, which should emerge reliably during midday warmth (11am-2pm) with highs in the low 70s. The weekend looks prime before Saturday's weather shift brings cooler temps and light precipitation. Focus on the canyon section above Driggs where less pressured fish are looking up for size #16-18 PMD patterns.
- Flow: 38 cfs — dramatically low for June but perfect wading. Crystal clear water demands careful approach but rewards precision casting.
- Hatches: PMDs at peak season. Expect midday emergence 11am-2pm when air temps hit low 70s. Size #16-18 Comparaduns and Sparkle Duns.
- Water Temp: Low flows mean rapid warming on sunny days. Prime PMD emergence zone of 52-55°F likely by late morning in current conditions.
- Best Window: Thursday-Friday midday before weekend weather shift. Saturday brings cooler temps and light precip — fish before the change.

About this Water
- Freestone
- Best months: May–Oct, peak June–Aug
The Teton River in eastern Idaho runs through Teton Valley between the Big Hole and Teton mountain ranges. The river divides naturally into two distinct fisheries: the upper meadow stretch (above the canyon) is a classic spring-creek-like meandering stream through pastoral ranchland, with abundant rainbow and Yellowstone cutthroat. The Teton Canyon section below Felt Dam is a steeper, faster freestone with native cutthroat in pocket water. Hatches are reliable: PMD and Green Drake in early summer, Mahogany Dun in fall.
The Teton Valley meadow stretch is considered one of the finest dry-fly waters in the Northern Rockies — broad shallow runs with consistent insect activity producing classic rising-fish opportunities throughout summer.
January Outlook
The Teton River in eastern Idaho is largely frozen and inaccessible in January. The valley is deep in snow and the river is not fishable. A winter rest for this beautiful cutthroat river.
Productive Patterns
- Closed — off season
Tips
The Teton's season runs from late May through October. January is for planning and gear preparation.
Water Notes
River iced or nearly so. Valley roads may require 4WD. Off season.
February Outlook
Still off-season on the Teton. Winter conditions persist in the valley. The river will come alive in May when runoff subsides.
Productive Patterns
- Closed — off season
Tips
Call Driggs or Rexburg fly shops in May for current conditions. The Teton's PMD and Caddis hatches are excellent in June.
Water Notes
River iced. Off season.
March Outlook
March sees the Teton beginning to stir but it's not yet fishable. Snowmelt from the Tetons begins building the river toward runoff. Occasional midge activity near Driggs on the warmest days.
Productive Patterns
- Zebra Midge
- RS2
Tips
Late March can produce brief midge activity on the Teton near Driggs. The season genuinely begins in May–June after runoff. The valley is beautiful as it emerges from winter.
Water Notes
300–800 cfs and rising. Water 38–48°F. Not yet prime.
April Outlook
April runoff arrives on the Teton from the high Teton Range snowpack. Flows peak in late April and May. Not a fishable month on this freestone river.
Productive Patterns
- Pre-season — high runoff
Tips
The Teton typically peaks in late April–May with snowmelt. Monitor the Driggs gauge. Season opens in earnest when flows drop below 600 cfs and clarity returns.
Water Notes
500–2,500+ cfs. Peak runoff with Teton snowmelt. Very high and turbid. Wait for June.
May Outlook
May runoff season on the Teton. Flows typically peak in mid-May with Teton snowmelt. The river usually clears enough for fishing in the last week of May in an average year.
Productive Patterns
- Stimulator
- Elk Hair Caddis
- Rubber Leg Nymph
- Streamer
Tips
The last week of May can be excellent on the Teton when flows drop quickly. Watch the gauge daily. When clarity returns, Caddis and early PMD activity can be outstanding.
Water Notes
1,000–3,000 cfs dropping. Clearing by late month in average years. First good fishing of the season.
June Outlook
The Teton River in eastern Idaho offers good dry fly fishing for cutthroat and brown trout. PMDs and Caddis produce consistent action.
Productive Patterns
- PMD
- Elk Hair Caddis
- Golden Stone
- Stimulator
Tips
The Teton is a beautiful, intimate river with less pressure than the South Fork Snake. Float or wade the canyon section above Driggs for the best fishing.
Water Notes
600–2,000 cfs in June. Runoff peaks in May–June. Target below 1,200 cfs for good fishing.
July Outlook
Excellent hopper-dropper fishing on the Teton. The scenic canyon and open meadow sections both produce good fish.
Productive Patterns
- Hopper-Dropper
- PMD Cripple
- Elk Hair Caddis
- Stimulator
Tips
The section from the canyon below Tetonia to the lower valley offers diverse water types. Float or wade depending on access. Evening caddis is productive.
Water Notes
400–900 cfs. Water 58–65°F. Excellent wading conditions.
August Outlook
Hopper season peaks on the Teton. The meadow sections near Driggs produce classic terrestrial fishing with a Teton Range backdrop.
Productive Patterns
- Dave's Hopper
- Chubby Chernobyl
- Parachute Ant
- Elk Hair Caddis
Tips
The Teton is one of the most scenically spectacular rivers in the West. Fish the meadow sections in the morning with hoppers and the canyon in the afternoon.
Water Notes
300–700 cfs. Water 60–66°F. Excellent conditions.
September Outlook
Fall fishing on the Teton with BWO hatches and streamer fishing for brown trout.
Productive Patterns
- Blue Winged Olive
- Hopper
- Streamer
- Copper John
Tips
The fall BWO hatch produces good dry fly fishing in September. Brown trout from the lower sections begin moving up for fall spawning.
Water Notes
250–500 cfs. Clear and cool 52–60°F. Excellent fall conditions.
October Outlook
October is excellent on the Teton. Brown trout are moving and aggressive before spawning. BWO hatches on overcast afternoons. The Teton Range backdrop in fall color is spectacular.
Productive Patterns
- Streamer
- Blue Winged Olive
- Egg
- Copper John
Tips
The Teton in October is one of southeast Idaho's finest fall experiences. Large brown trout from the lower sections are moving up. Fish the deeper pools and seams with streamers.
Water Notes
250–500 cfs. Cold 42–52°F. Clear and beautiful. Fall colors in the Teton Range are exceptional.
November Outlook
November closes the Teton season. Cold temperatures and the approaching winter make fishing difficult. A quiet end to the season.
Productive Patterns
- Zebra Midge
- RS2
- Pheasant Tail
Tips
November fishing is possible in the canyon sections on mild days. Fish noon–2pm. The river is essentially done for the year by mid-November.
Water Notes
200–400 cfs. Cold 36–46°F. Canyon sections stay open. Off season approaching.
December Outlook
The Teton is closed for the winter season. Heavy snow in the valley makes access difficult. Plan the spring season from home.
Productive Patterns
- Off season
Tips
The Teton valley receives significant winter snowfall. December is for cross-country skiing and planning the summer float trip season.
Water Notes
Off season. River cold and partially iced. Canyon roads may be impassable.
