Route logistics
Access and shuttle
A roughly 7.1-mile roadside Class II+ upper Yankee Fork section from the Custer Pullout through the West Fork confluence to Pole Flat Campground, linking the historic upper corridor to the existing lower Yankee run.

This changes launch and take-out logistics, not today's river score.
Peltier Lake to Long Lake is the full route. Shorter access pairs are useful when wind, time, or group energy changes the plan.

Put-in
Custer Pullout / Yankee Fork RoadUse only the named public launch or landing; a nearby bank, bridge shoulder, fishing easement, or private campground is not substitute access.
Take-out
Pole Flat Campground / Yankee Fork WeirConfirm current closures, fire restrictions, seasonal gates, parking capacity, fees, launch condition, and Idaho invasive-species requirements before travel.

Access caveats and watch for
Access caveats
- Use only the named public launch or landing; a nearby bank, bridge shoulder, fishing easement, or private campground is not substitute access.
- Confirm current closures, fire restrictions, seasonal gates, parking capacity, fees, launch condition, and Idaho invasive-species requirements before travel.
- Private banks are common. Do not land, scout, portage, or camp outside a signed public site or manager-designated corridor.
Watch for
- mobile wood and changing channels
- West Fork transition
- cold water and fast rise
- roadside carries
- Pole Flat monitoring/campground endpoint

Why this scoreToday's evidence strength is checking
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.
- Checking evidence-strength notes.
- Checking evidence cautions.

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Official route corridorCuster Pullout to Pole Flat Campground; About 7.1 river miles
American Whitewater Yankee Fork upper-road-end reach record identifies the endpoint chain, river miles, or managed float corridor.
- Public access controlCuster Pullout / Yankee Fork Road to Pole Flat Campground / Yankee Fork Weir
Coordinates represent named public ramps, bank launches, park landings, or an explicitly described staging point.
- Direct live gaugeUSGS 13296000 - Yankee Fork Salmon River near Clayton, ID
Gauge is on the named waterbody and supplies context only.
- 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 the Yankee Fork as mellow and floatable above the roadside Class III+/IV+ lower miles, but the gradient, wood, and channel character change quickly near the West Fork and Pole Flat. Use a proven crew and scout from Yankee Fork Road before committing. The direct 13296000 gauge is near Clayton and is most informative for the lower Yankee; do not transfer its reading mechanically to the upper Custer corridor. Confirm local depth, wood, and road access at the launch and at every bridge or campground transition. AW trip reports describe about 1,500 cfs as a great downstream run and 1,800-2,000 cfs as Class IV; those markers are planning context rather than a hard upper-section safety limit. Reduce the objective or take out early if wood, snowmelt, or private-frontage constraints change the risk. Pole Flat is a deliberate endpoint. Continuing downstream enters the separate Pole Flat-to-Salmon card; reassess the final bend, wood, daylight, and the next shuttle before linking sections.
- Camping classificationendpoint_campground
Pole Flat is a developed Forest Service campground when open, with additional seasonal campgrounds along the Yankee Fork corridor. Custer is a day-use historic site; do not assume overnight camping at the pullout or any riverbank transition.

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.
