East Fork South Fork Salmon River

Evidence strength mostly comes down to three things: how direct the active gauge is, how clear the range is, and how fresh the data is.

These are the live readings and threshold notes behind today's score.

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

• Official route corridorSheep Creek Trailhead to South Fork Salmon River; About 9.1 river miles

  American Whitewater East Fork South Fork Salmon lower reach record identifies the endpoint chain, river miles, or managed float corridor.

• Public access controlSheep Creek Trailhead put-in to South Fork Salmon confluence access

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

• Defensible proxy gaugeUSGS 13313000 - Johnson Creek at Yellow Pine, ID (proxy for East Fork South Fork Salmon)

  Gauge is downstream on the same river system and must not be treated as a local measurement.

• Threshold postureNumeric cue retained for planning

  The route remains planning-only; no live go/no-go score is asserted.

• Safety and land managementCurrent manager notices override this record

  American Whitewater describes Class V Flight Simulator near the upper section, followed by sustained Class IV and easier Class III water downstream. The standard Sheep Creek Trailhead start avoids the hardest upstream drops but still requires a proven Class IV crew, rescue kit, cold-water protection, and conservative scouting. Logs, blind horizons, and the active upper section can change by season. Scout Flight Simulator, Ex-Lax, and every wood-affected channel from the road where possible; portage rather than commit to a blind line. Sheep Creek Trailhead is the standard put-in; Caton Creek and Deadman Bar are named alternates. The South Fork take-out is remote and close to the confluence—verify the landing and do not continue downstream unintentionally. Use the 300-1,000 cfs Johnson Creek-at-Yellow-Pine correlation as a planning shoulder only. It is a proxy for the East Fork; local level, wood, trend, weather, and scouting override the number.

  Deadman Bar Campground is a named intermediate staging option when open. This card does not imply a river-camp itinerary; use only current Forest Service sites and posted rules.

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