Fly Fishing Snake River - Below Flat Creek

Fly fishing Snake River below Flat Creek (Jackson) gives anglers a chance to work a productive stretch of river just outside the town of Jackson. This section picks up the flow of Flat Creek and other small tributaries, creating a broad river corridor dotted with cottonwood-lined banks and gravel islands. Cutthroat trout thrive here, often holding tight to seams and eddies where Flat Creek's cooler water enters the Snake. Optimal wading conditions occur in late summer and fall when flows recede to ~300–800 CFS, exposing side channels and riffles that are inaccessible during spring runoff. During these months, anglers can wade-fish around South Park Bridge and the Emily Stevens Park access, targeting rising cutthroats with hopper-dropper rigs and attractor dry flies. Access is convenient – public boat ramps and fishing easements line the river just south of Jackson. Notable access points include the Highway 89 Bridge and Wilson Bridge downstream. The Flat Creek confluence area is a hot spot, as trout congregate to feed on aquatic insects and terrestrials flushed in from the creek. Seasonal highlights include a prolific summer Yellow Sally and caddis hatch that brings even larger cutthroats to the surface in the evenings. In early fall, kokanee salmon from Palisades Reservoir migrate upriver, and trophy brown trout follow, providing exciting streamer fishing opportunities for anglers hunting bigger fish. This Jackson-area section of the Snake River offers a mix of classic riffle-run water and braided side channels that are perfect for walk-and-wade fishing when flows are moderate. Trout here average 12–18 inches, with the occasional 20+ inch cutthroat or brown lurking in deeper pools. Anglers are treated to stunning views of the Teton Range to the north and frequent wildlife sightings – expect to share the river with moose, waterfowl, and bald eagles. With easy access and abundant, willing trout, the Snake River below Flat Creek is an ideal stretch for anglers of all skill levels to enjoy world-class fly fishing minutes from downtown Jackson.
