FloatETA estimates how long this float actually takes from live discharge at USGS 13317000 (Salmon River at White Bird), not a guidebook average. At a typical 10,000 cfs, a raft drifts about 4.5 mph here. Higher flow speeds you up; skinny water slows you down. Kayaks run faster than the current, tubes slower. Optional fishing adds 35 minutes per mile.
The Salmon River (Riggins) listing covers 81 river miles across 2 access-to-access stretches (Class III, Class II–III). Times in the table are typical raft hours at that reference flow. Open the live calculator for today's CFS, sunset take-out, water temperature, and rain/UV at the put-in.

Float stretches on the Salmon River (Riggins)
| Put-in → take-out | Miles | Difficulty | Typical raft time | Notes |
|---|---|---|---|---|
| Riggins city → Lucile | 8 mi | Class II–III | ~1 hr 47 min | Town-to-town. Warm water in summer, jet boats possible. Time Zone Rapid is the named drop. |
| Hammer Creek → Heller Bar (Snake confluence) | 73 mi | Class III | ~16 hr 13 min | The Lower Salmon. Typically 3–4 days. Snowhole is the big rapid. BLM camps, rattlesnakes, and a serious shuttle. |
How we time this river
Speed scales with discharge using hydraulic geometry v ∝ Q0.34, calibrated to this gauge. That is why a 1,000 cfs afternoon is a different day than 3,000 cfs runoff. Always scout, wear a PFD, and check Idaho Fish and Game for closures. Gauge page: USGS 13317000.
Common questions
How long does it take to float Riggins city to Lucile on the Salmon River (Riggins)?
About 1 hr 47 min in a raft at a typical 10000 cfs. Kayaks run a bit faster; tubes run slower. Stopping to fish adds about 35 minutes per mile. Town-to-town. Warm water in summer, jet boats possible. Time Zone Rapid is the named drop.
How long does it take to float Hammer Creek to Heller Bar (Snake confluence) on the Salmon River (Riggins)?
About 16 hr 13 min in a raft at a typical 10000 cfs. Kayaks run a bit faster; tubes run slower. Stopping to fish adds about 35 minutes per mile. The Lower Salmon. Typically 3–4 days. Snowhole is the big rapid. BLM camps, rattlesnakes, and a serious shuttle.
What USGS gauge is used for Salmon River (Riggins) float times?
FloatETA uses USGS gauge 13317000 (Salmon River at White Bird) for live discharge. Speed is scaled from a reference 10000 cfs drift of about 4.5 mph.
Is the Salmon River (Riggins) a good tube float?
Tubes lag the current (we use a 0.72× speed multiplier). This listing includes Class III or harder water — rafts and experienced paddlers, not tubes.
