The Salt River is Star Valley's home water, and it fishes like a river most of Wyoming forgot about. It runs roughly 84 miles from the Salt River Range north through the ranch country around Afton, Grover, Thayne, and Etna before dumping into Palisades Reservoir near Alpine. What you're fishing is a spring-influenced freestone — cold groundwater and named feeder creeks (Cottonwood, Stump, Willow, Strawberry, Cedar) keep it running clear and cold through a long season. The resident fish are wild Snake River fine-spotted cutthroat and brown trout in the 10–14" range, with a real population of 16–18" fish and browns pushing past 20", especially in fall when they run up out of Palisades. A few rainbows and brook trout mix in toward the headwaters. It doesn't get the traffic the Snake or the South Fork gets an hour north, and that's the whole appeal.

Practically, this is a float river more than a wade river. Much of the bank is private ranchland lined with willows, so a drift boat or raft gets you to water you can't reach on foot, and guides run the Afton-to-Alpine corridor almost entirely from boats. That said, Wyoming Game & Fish maintains a string of public access areas with primitive launches — Narrows Bridge, Diversion (Murray), Creamery Road — so a wade angler willing to read the highway signs north of Afton can find pocket riffles and cut-bank pools. The character shifts as you move downvalley: braided spring-creek flats up near Afton, a swift willow-choked pinch through the Narrows between Grover and Thayne, then slower pastoral meanders with deep holding bends from Thayne down through Etna to the reservoir. Around 500 CFS is the sweet spot for floating — moving well but manageable.

Timing matters here. Snowmelt off the Salt River Range blows the river out and colors it through May into mid-June; the season really opens after runoff drops, late June through November. June and July bring stonefly and PMD activity, August and September are terrestrial months, and fall is the payoff — prolific Baetis, then streamer season as the big browns get aggressive pre-spawn through December. Late-summer flows drop low enough that the fishing gets tougher and the fish get spooky. Two special-regulation wrinkles are worth knowing before you go (see Regulations): the drainage above the Upper Narrows Bridge closes to trout harvest November 1–December 31, and a long middle reach below the Hwy 238 bridge is flies-and-lures-only year-round.

Species

  • Snake River Fine-Spotted Cutthroat Trout
    Abundant · Jun-Oct · 10-16"

    The signature native fish, strongest through the upper river and headwaters. Fine, pepper-like black speckling toward the tail, and eager to attractor dries — the reason to fish the Salt.

  • Brown Trout
    Common · Sep-Dec · 12-20"+

    The trophy potential on the river. Big browns run upstream out of Palisades Reservoir Oct–Dec and stage in the deep lower meanders — the prime fall streamer target, especially the Etna-to-Alpine reach.

  • Brook Trout
    Present · Jun-Sep · 6-12"

    Scattered through the upper river and cold feeder tributaries near Afton. Small and eager on dries.

  • Rainbow Trout
    Present · Jun-Oct · 10-16"

    A minority of the population — present but not the draw, mixed in with the cutthroat throughout the valley.

  • Mountain Whitefish
    Common · Year-round · 10-16"

    Native throughout the Snake River drainage and common here; incidental on nymphs and a good shoulder-season target when the trout are sluggish.

Ideal wading flow300–800 CFS
Blow-out>1,500 CFS
Ideal water temp48–62°F

Fall (Sep–Dec) is the payoff — prolific Baetis, tailing-off terrestrials, and big pre-spawn browns running up from Palisades, with streamer season stretching into December. Early-to-mid summer (late Jun–Jul) is the other window: post-runoff stoneflies and PMDs over prime float flows, with ~500 CFS the widely cited sweet spot. August brings hoppers over dropping, clearing water. Spring offers a brief pre-runoff BWO and midge window before the May snowmelt blowout. Watch gauge 13027500 above the reservoir near Etna — the ideal float range is roughly 400–600 CFS, and quality drops off below about 250–300 CFS in late summer.

Sections

3 sections on this river

Lower Salt — Etna to Alpine

FloatCutthroat · Brown Trout · Rainbow Trout

Slower, deeper pastoral meanders with big bends, eddies, and deep holding pools from Etna down toward Palisades Reservoir. The USGS gauge above the reservoir sits mid-reach, and Creamery Road anchors the primitive launches. This is where the browns stage and run up out of the reservoir in fall — the deepest, biggest-fish water on the river.

Best for: Big brown trout on streamers during the fall pre-spawn run out of Palisades, plus PMD and Baetis dry fishing for Snake River cutthroat. Float preferred through the private-bank meanders.

The Narrows — Narrows Bridge to Etna

FloatCutthroat · Rainbow Trout

Where the two ranges pinch the valley together between Grover, Bedford, and Thayne — swift riffle water under heavy overhanging willows, with Jensen Creek adding cut banks and riffles near the Narrows Bridge. Short runs between the Narrows Bridge and Diversion access areas make this the classic float pace, and around 500 CFS reads best.

Best for: Prospecting riffles and willow banks for Snake River cutthroat and rainbow trout — golden stones, caddis, and hoppers on a dry-dropper from a boat.

Upper Salt — Afton to the Narrows

Wade & FloatCutthroat · Brook Trout · Rainbow Trout

Smaller, spring-influenced water winding through the ranch flats around Afton, Grover, and Auburn — braided channels, cut banks, and riffle-pool water fed by cold feeder creeks. Above the Upper Narrows Bridge (WY Hwy 238) this is where the special Nov 1–Dec 31 catch-and-release regulation applies. The most cutthroat-dominated, spring-creek-like reach on the river.

Best for: Snake River cutthroat trout on dries, with brook trout mixed in toward the upper reaches. Dry-fly and light nymphing in the quietest, lowest-pressure water on the Salt.

Regulations

Current fishing rules and restrictions

The Salt River is in Wyoming Game & Fish Area 1 (Snake, Salt, Greys, Hoback drainages). Two special regulations apply: the drainage above the Upper Narrows Bridge (WY Hwy 238) is catch-and-release for trout Nov 1–Dec 31, and a middle reach below the Hwy 238 bridge down to the Diversion (Murray) Fishing Access is flies-and-lures-only year-round. General Area 1 stream rules apply elsewhere. Open year-round, though the practical season is late June through December.

  • Salt River drainage upstream of the Upper Narrows Bridge (WY Hwy 238): all trout released immediately Nov 1 – Dec 31, artificial flies and lures only during that period
  • From 1/4 mile below the Hwy 238 bridge downstream to the Diversion (Murray) Fishing Access (as posted): artificial flies and lures only, year-round
  • General Area 1 stream creel limit: 3 trout daily, no more than 1 over 16"
  • No more than 1 cutthroat over 12" in the daily limit
  • Use or possession of live baitfish is prohibited throughout Area 1 (dead approved baitfish permitted)
  • Wyoming resident or nonresident fishing license required; conservation stamp required

Some older sources cite a Salt-specific limit of 6 trout — the current Area 1 stream default of 3 trout appears to govern, but confirm against the current-year Chapter 46 regulations before keeping fish, as creel limits and special-regulation reaches are revised periodically. The neighboring Greys River carries its own flies-and-lures-only reach from Corral Creek to the Murphy Creek Bridge.

Access & Logistics

Getting there, fly shops, and lodging

Getting There

Afton, WY

About 1 hr south of Jackson via Hoback Junction and the Snake River Canyon; Jackson Hole Airport (JAC) ~1 hr; Idaho Falls (IDA) ~2.5 hrs.

Fly Shops

Camping & Lodging

Afton is the largest town on the corridor — groceries, gas, the local shop, and lodging — with Thayne, Etna, and Alpine strung north toward Palisades. Alpine has the most tourist lodging as the gateway to the reservoir and the Snake. Dispersed and developed Forest Service camping sits up the Greys River and in the Salt River Range in the Bridger-Teton NF.

A float-first river — much of the bank is private ranchland, and guides run it almost entirely from drift boats and rafts. Wade access is limited to the WGFD public access areas (Narrows Bridge, Diversion/Murray, Creamery Road) with primitive launches; watch for access signage north of Afton. Respect private-land boundaries between the public reaches.

Star Valley

Greys RiverWY

A 50-plus-mile freestone that drops out of the Wyoming Range to meet the Snake at Alpine, the Greys is one of the few genuinely wild cutthroat rivers in the West you can fish from a gravel road. More than 95% of its trout are native Snake River fine-spotted cutthroat, and they come up hard for attractor dries from July through October once spring runoff drops out.

Other regions

Buffalo Fork RiverWY

The wild, back-of-beyond cousin to the Snake it feeds — a small snowmelt freestone that gathers its North and South Forks deep in the Teton Wilderness and comes together in Buffalo Valley before joining the Snake near Moran. Almost pure Snake River fine-spotted cutthroat water, with mountain whitefish thick enough to rise during a stonefly emergence. The lower river along Buffalo Valley Road is an easy float-or-wade cutthroat float; the upper forks are a backcountry pack trip. No dam to steady it, so it fishes best on the drop from August into September.

Firehole RiverWY

The most unusual trout stream in the Lower 48 — a geyser-fed meadow river inside Yellowstone NP with vast White Miller caddis hatches, PMD and BWO windows, and a short fishing season (late May through early July, then September to early November) bracketing a summer that's too warm to fish.

Gibbon RiverWY

The Firehole's quieter sibling — the other geothermally-influenced headwater that joins it at Madison Junction to form the Madison. Technical spring-creek meadow flats above Gibbon Falls (the biggest fish) and forgiving canyon pocket water below, holding wild brown, rainbow, brook, native westslope cutthroat, and the odd Arctic grayling. A spring-and-fall fishery inside Yellowstone NP.

Gros Ventre RiverWY

The walk-and-wade counterpart to the crowded Snake River float scene in Jackson Hole — a medium freestone that drops out of the Gros Ventre Wilderness past the 1925 slide and its two slide lakes, then runs through the National Elk Refuge and Grand Teton National Park corridor to meet the Snake. Wild Snake River fine-spotted cutthroat eat attractor dries from July into fall once runoff drops; irrigation diversion pulls the lower river down hard by late summer.

Hoback RiverWY

The small roadside freestone you drive right past heading south out of Jackson — US-189/191 traces it the whole way down Hoback Canyon to the Snake at Hoback Junction. Wade-only water, mostly 15 feet wide, holding native Snake River fine-spotted cutthroat that charge attractor dries. Most fish run 8–13 inches, with bigger migratory Snake River cutthroat pushing up in late spring and early fall; the early-summer salmonfly and golden stone hatches are the marquee event once runoff drops in late June.

Lamar RiverWY

The marquee Yellowstone cutthroat river — a freestone rolling out of the Absaroka wilderness through the wide-open Lamar Valley, where pure Yellowstone cutthroat sip drakes and hoppers in glassy meadow runs. Sight-fishing on foot for 14-20"+ fish; comes into shape mid-to-late July and stays flash-prone all summer.
