South Fork Clearwater RiverHanging Rock to Cougar Creek Trailhead (Golden Canyon)

These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.

• Official route corridorHanging Rock to Cougar Creek Trailhead (Golden Canyon); About 7.2 river miles

  American Whitewater Golden Canyon reach and access description identifies the endpoint chain, river miles, or managed float corridor.

  Coordinates represent named public ramps, bank launches, park landings, or an explicitly described staging point.

• Direct live gaugeUSGS 13338500 - South Fork Clearwater River at Stites, ID

  Gauge is on the named waterbody and supplies context only.

• Threshold postureGauge-linked range used for live scoring

  The cited route guidance is tied to this gauge and reach; hazards, closures, weather, and local inspection still override the score.

• Safety and land managementCurrent manager notices override this record

  This is a committing Class IV-V roadside run with steep continuous rapids, cold water, and limited recovery below the major drops. Use a proven expert crew, whitewater kayaks or an appropriately small craft, helmets, throw bags, rescue hardware, repair kit, and satellite communication. American Whitewater identifies Coyote Falls upstream, Chuck Rollins around highway milepost 25.4, Fish Jump around milepost 22.4, and the Cougar Creek Trailhead around milepost 20.6. Scout or portage these features before committing; the road corridor helps, but does not make a swim safe. Use 600 cfs as the conservative lower planning floor from the Idaho basin plan and 1,000-2,000 cfs as the lower technical ideal from American Whitewater. At 2,000-4,000 cfs the reach carries multiple solid Class V features; above 4,000 cfs is expert big water, not a scored upper-safe limit. The Cougar Creek exit is a highway trailhead/parking control rather than a developed ramp. Confirm the trail, roadside parking, seasonal road condition, and current access legality before launch; continue downstream only if separately prepared for the easier but longer corridor.

• Camping classificationnearby_basecamp

  No on-route camping is assumed. Use a lawful nearby basecamp in the Stites/Kooskia corridor or a current Forest Service campground; the highway trailhead is a take-out, not an overnight site.

  Adjacent cards use different public endpoints and provide a different trip length, hazard set, skill tier, or operating boundary.
