⚠️ REGULATIONS

  • Artificial flies & lures only

Snake River, Moose (Grand Teton National Park boundary) downstream to the Wyoming Highway 22 Bridge (Wilson Bridge) — Wyoming Game & Fish Area 1 regulations (2026 brochure, item 15). This reach falls within the WGFD-defined zone running from the USGS gauging station 1,000 feet below Jackson Lake Dam downstream to Wilson Bridge, which is entirely artificial flies and lures only. All cutthroat trout must be released immediately November 1 through March 31. No creel override is listed for this reach, so the standard Area 1 stream limit applies: 3 trout per day, no more than 1 exceeding 16 inches, no more than 1 cutthroat trout exceeding 12 inches. Live baitfish prohibited. Maximum 3 hooks/devices per line (statewide rule). Valid Wyoming fishing license required. See https://wgfd.wyo.gov/regulations.

Overview

The Snake from Moose toward Wilson winds through braided channels, gravel bars and cottonwood-lined banks beneath the Teton Range. Cutthroat trout and mountain whitefish are part of its fishery, with side currents, deeper runs and woody cover creating varied holding lies. The setting combines open valley views with closely spaced seams within the river’s braids.

Working the Braided Water

Snowmelt and upstream reservoir releases influence the channel’s depth and current. Read the chosen run before making a cast, looking for a softer edge, the tail below a riffle or a seam where currents rejoin. A gravel bar’s appearance does not establish the depth or footing beyond it.

Caddis, pale morning dun, stonefly and blue-winged olive imitations offer choices when insects or feeding fish suggest them. During warmer weather, hoppers, beetles and ants provide terrestrial options beside grassy banks. A foam attractor or dry-dropper can search a defined edge, while a smaller dry fits a slower feeding rhythm.

Nymphs and streamers offer presentations for deeper runs and submerged structure. Keep the drift controlled and vary depth with the lie. Autumn cottonwoods add another layer to the landscape, while the river’s changing channels continue to reward a close look at the current.
