Put-in
Camp 3 Campground / Forest Road 321 LaunchUse only the named public launch or landing; a nearby bank, bridge shoulder, fishing easement, or private campground is not substitute access.
Take-out
Marble Creek Interpretive Center 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
- mobile wood and blind Class IV drops
- sparse eddies and long swims
- seasonal Road 321 access
- hand-gauge scour and downstream Calder proxy

Score & sources
Data and sources

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 corridorCamp 3 to St. Joe Confluence; About 13.9 river miles
North Idaho Rivers Marble Creek guide identifies the endpoint chain, river miles, or managed float corridor.
- Public access controlCamp 3 Campground / Forest Road 321 Launch to Marble Creek Interpretive Center 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
American Whitewater and North Idaho Rivers describe continuous Class III+ with standout Class IV drops, long swims, and sparse eddies. Use a proven creeking boat, helmet, rescue kit, and a tight group. Logs are a serious, shifting hazard on the full creek. Road 321 allows partial scouting, but blind corners and channels still require getting out to inspect; portage only where the Forest Service corridor and terrain make it safe. The 3,500-4,000 cfs Calder cues are downstream proxy guidance. The local confluence hand gauge is difficult to interpret after channel scour; current wood, weather, road opening, and same-day trend override the number.
- Camping classificationnearby_basecamp
Camp 3, Marble Creek Campground, and other named Forest Service sites along Road 321 provide nearby basecamp options; verify seasonal openings, fees, sanitation, fire rules, and road conditions.
- Image decisionSt. Joe watershed context photograph; Marble Creek endpoint not depicted
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.
