Put-in
Loop Creek Put-InUse only the named public launch or landing; a nearby bank, bridge shoulder, fishing easement, or private campground is not substitute access.
Take-out
St. Joe Confluence Take-OutConfirm 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
- new wood and continuous Class III
- Moon Pass access
- small confluence turnout
- hand gauge at Avery and downstream-gauge mismatch

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 corridorLoop Creek to St. Joe Confluence; About 10.4 river miles
USFS St. Joe Wild and Scenic River plan identifies the endpoint chain, river miles, or managed float corridor.
- Public access controlLoop Creek Put-In to St. Joe Confluence Take-Out
Coordinates represent named public ramps, bank launches, park landings, or an explicitly described staging point.
- Defensible proxy gaugeUSGS 12414500 - St. Joe River at Calder, ID (downstream proxy)
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
Class III continuous water and new wood require a proven whitewater craft, helmet, rescue equipment, and an experienced crew. Loop Creek is a primitive ramp with seasonal Moon Pass access; the confluence landing is a small turnout near dumpsters—do not block the service area. North Idaho Rivers describes a hand-painted local gauge at Avery and recommends at least 4,000 cfs on the downstream Calder gauge; the 2,500-15,000 cfs American Whitewater range remains planning guidance because Calder is downstream of the North Fork.
- Camping classificationnearby_basecamp
No on-route camping is assumed; use open Forest Service campgrounds or a lawful St. Maries/Avery basecamp.
- Image decisionNorthern Idaho St. Joe watershed context photograph
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.
