Float ETA estimates how long this float actually takes from live discharge at USGS 13333000 (Grande Ronde River at Troy), not a guidebook average. At a typical 2,000 cfs, a raft drifts about 3 mph here. Higher flow speeds you up; skinny water slows you down. Kayaks run faster than the current, tubes slower. Add your own total time for stops and fishing.
This is a multi-day wilderness float. Plan shuttles, permits, and camps — the calculator shows total hours on the water, not a same-day take-out.
The Grande Ronde River listing covers 45 river miles across 1 access-to-access stretch (Class II). 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 Grande Ronde River
| Put-in → take-out | Miles | Difficulty | Typical raft time | Notes |
|---|---|---|---|---|
| Minam → Troy | 45 mi | Class II | ~15 hr | Usually 3–4 days. The Wenaha River comes in at Troy. Few roads, so plan your shuttle ahead. |
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 the Oregon State Marine Board for closures. Gauge page: USGS 13333000.
Common questions
How long does it take to float Minam to Troy on the Grande Ronde River?
About 15 hr in a raft at a typical 2000 cfs. Kayaks run a bit faster; tubes run slower. Add your own stop or fishing time in the planner. Usually 3–4 days. The Wenaha River comes in at Troy. Few roads, so plan your shuttle ahead.
What USGS gauge is used for Grande Ronde River float times?
Float ETA uses USGS gauge 13333000 (Grande Ronde River at Troy) for live discharge. Speed is scaled from a reference 2000 cfs drift of about 3 mph.
Is the Grande Ronde River a good tube float?
Tubes lag the current (we use a 0.72× speed multiplier). On Class I–II stretches tubes can work at moderate flows; skip high water and always wear a PFD.
