Salmon RiverEast Fork Recreation Site to Bayhorse Recreation Site

This rating reflects whether the gauge measures this part of the river, whether published water-level guidance is available, and how recently the data was updated.

These readings and published water-level limits help explain today’s score.

These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.

• Official route corridorEast Fork Recreation Site to Bayhorse Recreation Site; About 11.7 river miles

  BLM/USFS/IDFG Upper Salmon boating guide identifies the endpoint chain, river miles, or managed float corridor.

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

• Direct live gaugeUSGS 13302500 - Salmon River at Salmon, ID

  Gauge is on the named waterbody and supplies context only.

  Source

• Threshold postureGauge-linked range used for live scoring

  The cited route guidance is tied to this gauge and reach; hazards, closures, weather, and local inspection still override the score.

  Source

• Safety and land managementCurrent manager notices override this record

  RiverBrain rates the East Fork-to-Challis corridor Class II but identifies two diversion dams and the Challis Rock Garden. Stay on the published safe side of each diversion and scout whenever the water is high, turbid, or changing. The 600-8,000 cfs envelope and 1,500-2,500 cfs planning band are reach guidance from the direct Salmon-at-Salmon gauge, not a safety guarantee for every rapid. Current wood, private frontage, cold water, weather, and craft choice control the launch decision. East Fork and Deadman Hole are public BLM access/camping areas; Bayhorse is a developed BLM/IDFG campground and ramp. Confirm seasonal opening, fees, parking, ramp condition, and current river-side carry before launch. This card ends at Bayhorse. Continuing downstream enters the separate Bayhorse-to-Challis Bridge route; re-check daylight, downstream wood, diversion features, and shuttle before linking sections.

• Camping classificationendpoint_campground

  East Fork offers developed seasonal camping; Deadman Hole has primitive dispersed camping; Bayhorse offers a developed fee campground with water, toilets, and a boat ramp. Confirm seasonal openings, fees, fire restrictions, and occupancy before relying on any site.

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