Salt River

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.
