Snake River

Wyoming's marquee cutthroat river and the soul of Jackson Hole — the Snake runs cold and clear beneath the Tetons, holding dense populations of native fine-spotted Snake River cutthroat through braided channels and cottonwood-lined runs. Flow is heavily shaped by Jackson Lake Dam releases; the classic float from Deadman's Bar to Moose is one of the West's great cutthroat drifts.

North Platte River

Wyoming's blue-ribbon trophy trout river — the North Platte runs north out of Colorado through the Saratoga valley, then below Seminoe and Alcova reservoirs it becomes the legendary Miracle Mile and Grey Reef tailwaters, some of the most productive big-trout water in the country. Grey Reef browns and rainbows average huge on scud, midge, and worm patterns; downstream toward Casper, Douglas, and Guernsey the river warms into walleye and catfish water.

Green River

One of the West's great trout rivers from its headwaters down — the Green pours off the Wind River Range near Pinedale as a clear freestone holding Colorado River cutthroat, browns, and rainbows at the famous Warren Bridge float, then below Fontenelle Reservoir it becomes a rich tailwater through the Seedskadee refuge before turning into a big desert river toward Flaming Gorge. Flow below Fontenelle is dam-release driven.

Yellowstone River

The heart of Yellowstone's native cutthroat fishery — the upper Yellowstone flows out of Yellowstone Lake and through Hayden Valley as a big, cold cutthroat river before plunging into the Grand Canyon of the Yellowstone. The famed Buffalo Ford water opens mid-July under strict catch-and-release rules for native Yellowstone cutthroat.

Wind River

A long, varied river running off the Absaroka and Wind River ranges through the Wind River Reservation and Riverton before pooling in Boysen Reservoir — cold trout water up high near Dubois holding cutthroat, browns, and rainbows, sliding into a warmer, bigger river by Riverton. Below Boysen it re-emerges as the Bighorn. Much of the middle river crosses the reservation, which requires a tribal permit.

Firehole River

One of the most storied trout streams on earth — the Firehole winds through Yellowstone's geyser basins, its water warmed by thermal runoff into a technical, meadow-and-canyon brown-and-rainbow fishery. Hatches are prolific and the fish are educated; summer heat can push water temps high enough to warrant closures, so it fishes best in early summer and fall.

Bighorn River

Wyoming's big-water trophy tailwater and warmwater river in one — where the Wind River emerges from Boysen Reservoir at the Wedding of the Waters it becomes the Bighorn, running cold and rich through Thermopolis as a blue-ribbon brown-and-rainbow tailwater, then warming downstream toward Basin and Kane into big walleye, sauger, and catfish water above Bighorn Lake. Flow is dam-controlled off Boysen.

Its tributaries Soda Butte and Slough Creek share the same magic.

Wyoming river conditions — FAQ

How current is the Wyoming river data?

Flow readings come straight from USGS gauges and refresh every 15 minutes. Every Wyoming river shows the exact reading time for each gauge, so you always know how fresh the number is.

Which Wyoming rivers are safe to wade or fish right now?

All 49 Wyoming rivers we track are rated Wadeable, Caution, Limited, or Blown out against thresholds tuned to each individual gauge. Open the dashboard for a live top-to-bottom read of every river.

What does CFS mean for wading?

CFS — cubic feet per second — is how much water is moving past the gauge. Higher CFS means faster, deeper, pushier water. The safe range differs on every river, which is why each gauge carries its own thresholds rather than one blanket number.

How much rain fell on Wyoming rivers, and how much is coming?

Each river page shows total observed rainfall over the last 48 hours plus the forecast for the next 48 hours at that gauge — the fastest way to tell whether the water is about to blow out or start clearing.

Do you cover my Wyoming river?

We track 49 Wyoming rivers behind live USGS gauges. Open any river for live conditions, species timing, public access points, and recent rainfall.
