About Clearwater River

Most anglers make the drive to the lower Clearwater for one fish: the B-run steelhead. These are the largest summer-run steelhead south of the Canadian border — ocean-going rainbows that average 10 to 13 pounds, run 31 to 34 inches, and give up a fish over 20 pounds somewhere on the river every season. They push in off the Snake at Lewiston in the fall and stack in the broad, even-depthed runs from the 95 Bridge up through Spalding, Lenore, and Peck. This is spey country in the truest sense: 13- to 15-foot two-handers, floating lines, and flies swung on a 70- to 80-degree downstream angle. The Red Shed Fly Shop out on Big Canyon Road near Peck is the spiritual center of it, and the fall Spey Gathering at the Lenore rest stop is the unofficial season opener.

The river fishes in two distinct modes. From September through March it's a swung-fly steelhead fishery on a huge canvas — the channel runs 100 to 300 yards wide, side-drifting from jet boats is the numbers game, and the swing is the purist's game. Then there's a shoulder-season trout window most out-of-staters miss: late May to mid-July and again from mid-September into October, the main stem gives up dry-fly westslope cutthroat and rainbows on PMDs, caddis, and Yellow Sallies. In the dead of summer the trout largely abandon the main stem — July and August water temperatures climb past 60°F and the fish retreat to the cold Lochsa and Selway upstream — so plan trout trips around the runoff drop, not the peak of summer.

A couple of things worth knowing. The North Fork Clearwater joins at Ahsahka, just below Orofino, and it comes out of Dworshak Dam — so everything downstream of that confluence carries a slug of regulated, dam-tempered water on top of the freestone Lochsa and Selway flow above it. That's why the Peck and Spalding gauges read roughly double the Orofino gauge. Spring runoff off the Bitterroot high country blows the main stem out and browns it, and it typically doesn't clear and settle until late June or July. Highway 12 parallels the river the whole way from Lewiston up, so wade access and boat ramps are everywhere — the trade-off is that you're never far from road noise. When the main stem is off-color or too warm, the cold tributaries (Lochsa, Selway, North Fork) are the fallback.

Species

  • Steelhead
    Primary · Oct-Nov, Feb-Mar · 30-37"+, 10-20+ lb

    The marquee fishery — B-run summer steelhead, the largest south of Canada. Fish enter off the Snake in the fall and run through March; the biggest push and most reliable conditions are Oct-Nov, with a spring window Feb-Mar. Only clipped-adipose (hatchery) fish may be kept; wild fish must be released. Smaller, earlier A-run fish (24-28") show near the Dworshak outflow and North Fork in Aug-Sep.

  • Westslope Cutthroat Trout
    Common · late May-mid Jul, mid Sep-Oct · 8-16"

    Native and no-harvest — catch-and-release only across the drainage. The dry-fly draw in the shoulder windows on PMDs, caddis, and Yellow Sallies. Retreats to the cold tributaries in mid-summer when the main stem warms past 60°F.

  • Rainbow Trout
    Common · late May-mid Jul, mid Sep-Oct · 8-16"

    Resident rainbows mixed in with the cutthroat, part of the same shoulder-season dry-fly catch. Look up in the pockets and along the edges when flows drop and cool.

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

    Ubiquitous native, a nymph-rig bycatch and a legitimate winter target in the slow water when nothing else is moving.

  • Bull Trout
    Present · Protected · to 24"+

    Native char, ESA-listed and catch-and-release only. Incidental — release immediately if you hook one on a swung streamer.

  • Smallmouth Bass
    Present · Jun-Sep · 8-15"

    Warmwater fishery in the lowest reaches near Lewiston and the Snake confluence, most active in the summer heat when the trout have moved off.

  • Chinook Salmon (spring run)
    Present · May-Jul · 15-20+ lb

    Popular seasonal fishery when open; the season and quota are set annually by IDFG. A fall run (10-20 lb) follows in Sep-Oct under permit.

  • Coho Salmon
    Present · Sep-Oct · 4-8 lb

    A reintroduced run from Nez Perce Tribe restoration, with occasional targeted seasons. Not a primary fly target but part of the drainage's anadromous mix.

  • Kokanee Salmon
    Present · — · 8-14"

    Present in the system but not a primary fly target on the main stem.

Sections

4 reaches

Middle Clearwater — Spalding to Peck / Lenore

Wade & FloatSteelhead

The river's signature swung-fly water — broad, even-depth spey runs at Lenore, Big Canyon (home of the Red Shed Fly Shop), and Cherrylane. This is the heart of Clearwater steelhead spey culture and the purist's stretch.

Best for: Steelhead on the swing with two-handed rods; wadeable runs plus drift and jet-boat access.

Upper Main-Stem — Peck to Ahsahka / Orofino

Wade & FloatSteelhead · Cutthroat · Rainbow Trout

The North Fork Clearwater enters at Ahsahka out of Dworshak Dam, adding cold regulated flow to the reach. Early A-run steelhead and shoulder-season westslope cutthroat and rainbow trout hold near the outflow where the water stays cold. Access at Pink House, Greer, and the Ahsahka area, though there is no fishing at the Dworshak National Fish Hatchery.

Best for: A-run steelhead near the Dworshak cold-water outflow; shoulder-season trout when the main stem is warm elsewhere.

Uppermost Main-Stem — Orofino to Kooskia

Wade & FloatSteelhead · Cutthroat · Rainbow Trout

The freestone upper main stem above the North Fork, closer to the Lochsa, Selway, and South Fork inputs. This is the clearest dry-fly water and the best trout character on the main stem, giving up westslope cutthroat and rainbow trout on dries in the shoulder windows (late May-mid Jul, mid Sep-Oct) and steelhead in fall. A September 1-April 30 no-motor rule applies from Orofino up to the Middle Fork/South Fork confluence at Kooskia.

Best for: Westslope cutthroat and rainbow trout on dries in the shoulder seasons — the trout window most steelheaders overlook; gateway to the Lochsa and Selway.

Lower Clearwater — Lewiston to Spalding (The Lower Four)

FloatSteelhead · Smallmouth

Wide, deep, slow tailout water where the Clearwater meets the Snake at Lewiston. The lowest dozen miles from the confluence up — the 95 Bridge to Casino stretch anglers call the Lower Four — hold the majority of fresh B-run steelhead early in the run. Smallmouth bass fill the summer months in these lower reaches.

Best for: The first stop for fresh steelhead staging off the Snake; side-drifting from jet boats is the numbers method on this big water, and smallmouth bass in summer.

Best seasons

For steelhead, the river fishes over a wide band — roughly 2,000 to 8,000 cfs at the Spalding gauge (13342500) swings well, and by September flows are dropped and stabilized for the season. Oct-Nov is the peak of the B-run and the most reliable conditions; Feb-Mar is the spring window as fish push through. Spring runoff off the Lochsa and Selway can push the main stem well past 40,000 cfs and brown it out — it usually doesn't clear and settle until late June or July. The trout shoulder windows (late May-mid Jul and mid Sep-Oct) want water in the high-40s to high-50s °F; July and August the main stem climbs past 60°F and the resident trout leave for the cold tributaries, making mid-summer the weakest window.

Regulations

The whole Clearwater drainage is under a barbless-hook rule when fishing for salmon or steelhead. Only clipped-adipose (hatchery) steelhead may be kept — wild fish are released. Cutthroat are catch-and-release only, and bull trout are fully protected. A September 1-April 30 no-motor reach runs from Orofino up to the Middle Fork/South Fork confluence.

  • Barbless hooks required throughout the Clearwater drainage when fishing for salmon or steelhead; a sliding-swivel weight rig with a lighter drop line is also required for steelhead
  • Steelhead: only clipped-adipose (hatchery) fish may be kept; wild steelhead must be released. Fall harvest opens Sep 1 below Memorial Bridge in Lewiston and on the North Fork; spring season runs roughly Jan-May. Steelhead permit required in addition to a fishing license
  • Cutthroat trout: no harvest — catch-and-release only across the drainage
  • Bull trout: catch-and-release only (ESA-listed)
  • Trout limit: general Idaho stream limit is 2 trout, but the Clearwater special rule allows a limit of 6 clipped-adipose (hatchery) steelhead/trout
  • No-motor reach Sep 1-Apr 30 from Orofino upstream to the Middle Fork/South Fork confluence at Kooskia
  • No fishing within posted boundaries of fish weirs and traps, the Nez Perce Tribal Hatchery ladder, or the Dworshak National Fish Hatchery shoreline
  • Idaho fishing license plus steelhead/salmon permits as applicable

Seasons and quotas for steelhead and salmon are set and adjusted annually by IDFG — always confirm the current-year rule book and any in-season announcements before your trip. Rules here reflect the 2025-2027 Idaho seasons.

Fly shops

  • House of FlyLewiston
  • Red Shed Fly ShopPeck

Camping: BLM recreation sites line Highway 12 (Pink House, Long Camp, Harpers Bend); motels in Lewiston and Orofino; Dworshak State Park sits nearby on the reservoir above Ahsahka.

Highway 12 follows the river the entire way from Lewiston up to Kooskia, with boat ramps and wade pullouts throughout — the Lenore rest stop, Cherrylane, Myrtle, and the Pink House and Greer areas are the standard put-ins. Lewiston is the hub for full services, licenses, and the regional airport. The Red Shed Fly Shop near Peck is the local intel center for the spey water; note there is no fishing or wading at the Dworshak National Fish Hatchery.
