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 corridorRough Creek Bridge to Yankee Fork Access; About 4.2 river miles

  American Whitewater Rough Creek-to-Sunbeam reach record identifies the endpoint chain, river miles, or managed float corridor.

• Public access controlRough Creek Bridge Informal Put-In to Yankee Fork Access Primitive Take-Out

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

• Defensible proxy gaugeUSGS 13296500 - Salmon River below Yankee Fork near Clayton, ID (downstream proxy)

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

  Source

• 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 and How's Your River identify Shotgun as a boulder garden that becomes Class IV at higher flows and the former Sunbeam Dam rapid as a consequential hole. Scout from river left and portage if the line, wood, or water level is not clearly manageable. RiverBrain's upper-Salmon cues and HYS's adjacent run guidance support a 600-6,800 cfs planning envelope; use 1,800-3,200 cfs as the conservative operating band for this short expert segment. The 13296500 gauge is below the Yankee Fork and is proxy context for the Rough Creek start. Rough Creek is an informal downstream-left bridge access, not a maintained ramp. The Yankee Fork endpoint is a primitive pull-off with no water and limited staging; inspect both carries and stage vehicles before launch. This card ends at the Yankee Fork access. Do not continue into the lower Sunbeam/Torrey reach without reassessing the additional Class III features, cold water, wood, daylight, and take-out logistics.

• Camping classificationnearby_basecamp

  No on-route overnight is assumed. Use a lawful Stanley-area or Mormon Bend basecamp and carry water; the Yankee Fork endpoint has no water or camping according to the access record.

  Approved route-area or same-river context; it does not depict every endpoint or current conditions.

• Overlap decisionRetained as a distinct access-to-access itinerary

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