Fly Fishing the Wind River, Idaho: Backcountry Solitude

A Wilderness Tributary at the Bottom of the Salmon Canyon

The Wind River drops into the main Salmon River from the north, about 23 road miles upstream of Riggins. Fish and Game maps it at 14.3 miles, all in Idaho County. The mouth sits at 1,970 feet, the lowest point in the Gospel-Hump Wilderness.

Congress designated the Gospel-Hump in 1978: 206,053 acres east of Riggins and north of the Salmon. The Forest Service calls the south half, where the Wind River runs, “dry and sparsely vegetated.” The country climbs to 8,940 feet at Buffalo Hump, and the Wind River trail gains 3,200 feet in its first 10 miles.

There are no roads in the drainage and no permits required. You park at the pack bridge, cross the Salmon on foot, and walk up the canyon.

If you were looking for Wyoming’s Wind River, this is not it. For more small waters in this state, see our Idaho secret waters guide.

Regulations (Checked September 2026)

The Wind River is not named in Idaho’s 2025 to 2027 rule book. Fish and Game’s Fishing Planner page assigns it the “Salmon River tributaries” special rule, which covers every tributary from the mouth of the Salmon up to the Middle Fork, except the Little Salmon and South Fork. Clearwater Region general rules fill in the rest.

The steelhead line matters more here than on most creeks. Idaho defines a steelhead as any rainbow over 20 inches in the Salmon River drainage, and fishing for steelhead is prohibited unless a season is specifically opened for that water. No season opens on the tributaries.

The main Salmon at the bridge runs under different rules. Trout limit is six, but only fin-clipped hatchery trout may be kept and no cutthroat at all. The middle Salmon steelhead seasons run January 1 to March 31 and September 1 to December 31, three fish a day.

The Fish: Never Stocked

Fish and Game has no stocking record for the Wind River. Every fish in it is wild.

The department’s 2023 survey recorded cutthroat trout and steelhead. Its 2021 crew found bull trout and salmonid fry. The 2018 survey listed westslope cutthroat, mountain whitefish, and steelhead. Brook trout appeared once, in 1996.

When a survey says “steelhead,” it means young rainbow trout of the ocean-going strain. In a Salmon River tributary, that is what a rainbow is. Some will leave for the sea and some will stay and grow into the resident fish you catch.

That list is narrower than the old advice about this creek. Fish and Game does not record redband trout or smallmouth bass here. Plan on cutthroat and small rainbows, with a bull trout in the deeper pools as a possibility, not a target.

Flows and Heat

No gauge has ever recorded the Wind River’s flow. The USGS lists two old site names on the creek, but neither holds a day of data. The nearest live gauge is on the Salmon River at White Bird, downstream of Riggins.

Source: USGS gauge 13317000, monthly means 1910–2025.

Read the canyon from that curve. The main river peaks in late May and June, and a low tributary like the Wind will have cleared before the Salmon does. By July the creek is small, clear, and walkable.

Heat is the other half of the story. From 2015 to 2026 the Salmon at White Bird averaged daily highs of 71 degrees in July and 72 in August, with a record of 78. The Wind River’s temperature has never been measured, but its canyon sits at 2,000 feet. Fish mornings in midsummer. September and October fish better than August.

Getting There

The trail follows the creek for roughly the first two and a half miles before it crosses the Wind River and switchbacks up the ridge. That lower stretch is your fishing water. Beyond the crossing you are hiking, not fishing.

Trail users on this side of the wilderness report rattlesnakes in the lower canyons, poison ivy along the river trail, and heat that is dangerous by afternoon in July and August. Carry more water than you think you need. The river road is passable for low-clearance cars but winds for about an hour.

How to Fish It

This is pocket water in a steep, rocky canyon. Cover it with short casts and a high-floating attractor dry, size 12 to 16, and add a small nymph dropper in the deeper slots. A 3- or 4-weight rod is plenty.

Keep your limit in mind: two trout, and no rainbow over 20 inches. Most anglers here release everything, and with a wild population that has never seen a hatchery truck, that is the right call. Bull trout must go back untouched.

Fish early, quit by early afternoon in summer, and give the fish a fast release in warm water. If you want to swing something bigger through the main Salmon on the walk back, remember the river’s own rules and the closed steelhead months.

Two other central Idaho waters make a natural loop with this one: Hazard Creek near Riggins and Bear Valley Creek to the southeast.

Frequently Asked Questions

Where is the Wind River in Idaho?

Idaho’s Wind River is a 14-mile Salmon River tributary in Idaho County. It enters the Salmon at the Wind River Pack Bridge, about 23 miles up the Salmon River Road from Riggins, at 1,970 feet. The whole drainage lies inside the 206,053-acre Gospel-Hump Wilderness. It has nothing to do with Wyoming’s Wind River.

What are the fishing rules on the Wind River?

Fish and Game’s planner assigns it the Salmon River tributaries rule: open all year, trout limit two. Brook trout limit is 25 and bull trout are catch-and-release. Any rainbow over 20 inches counts as a steelhead and must go back, since no steelhead season opens on the tributaries. Salmon fishing is prohibited. No bait ban, no barbless rule.

When is the best time to fish the Wind River?

July through October. There is no gauge on the creek, but the Salmon River at White Bird averages 36,900 cubic feet per second in June and 12,900 in July. Runoff lasts into early summer. The main river runs above 70 degrees in July and August. Fish the creek early in the day in midsummer. September and October are best.

What fish live in the Wind River?

Fish and Game’s 2023 survey found cutthroat trout and juvenile steelhead. Bull trout were recorded in 2021, westslope cutthroat and mountain whitefish in 2018, and brook trout in 1996. The creek has never been stocked.
