Route logistics
Access and shuttle
A demanding Yellowstone wilderness-edge canoe route that crosses Lewis Lake and then follows the only park river section open to non-motorized boating into Shoshone Lake.

Pick a shorter segment
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
Lewis Lake Campground boat rampUse only the named public or land-manager access; a nearby shoreline is not proof of a legal launch.
Take-out
Shoshone Lake channel outlet / backcountry boundaryConfirm seasonal gates, parking, fees, permits, AIS inspection, carry path, and take-out status immediately before the trip.

Access caveats and watch for
Access caveats
- Use only the named public or land-manager access; a nearby shoreline is not proof of a legal launch.
- Confirm seasonal gates, parking, fees, permits, AIS inspection, carry path, and take-out status immediately before the trip.
- Private banks and easements may constrain landing, scouting, camping, or portage; remain within the authorized corridor.
Watch for
- shallow rocky channel, wading/lining, low water, and cold shock
- strong afternoon winds and waves on both lakes
- remote wilderness, bears, no cell service, and changing dock/campsite conditions

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 corridorLewis Lake Campground launch to Shoshone Lake via Lewis River Channel; About 14–16 water miles one way (planning estimate; Lewis Lake crossing plus channel and Shoshone entry)
Yellowstone NPS Boat Safety and Regulations booklet identifies the access pair and operational character.
- Defensible proxy gaugeUSGS 13010065 — Snake River above Jackson Lake at Flagg Ranch, WY (proxy for Yellowstone lake/channel conditions)
Gauge is upstream or downstream in the same regulated river system; it cannot substitute for a local scout or dam-release notice.
- Threshold postureMinimum-only planning model with no numeric cutoff
No live scoring is justified from the available route-specific evidence; the model is intentionally planning-only.
- Public access controlLewis Lake Campground boat ramp to Shoshone Lake channel outlet / backcountry boundary
Named agency/park access points are retained, including any intentional parking or campground offset from the shoreline.
- Safety and land managementPFD, AIS, water temperature, current hazards, and current closures govern the decision
Review current agency rules, dam/release notices, wind, debris, and private-bank restrictions before launching.
- Camping classificationnone
No developed camping on route. Yellowstone backcountry campsites around Shoshone Lake require an advance or walk-in backcountry permit, food-storage plan, and current campsite status; a same-day out-and-back is not assumed.
- Image decisionYellowstone NPS lake context photograph
Approved same-watershed context image; it is not presented as a photograph of this exact reach.
- Overlap decisionRetained as a distinct access-to-access card
Adjacent cards have different launch/take-out pairs, operational boundaries, difficulty, or trip length; no duplicate corridor was found in the Wyoming baseline.
