Snake River Canyon flow is set by releases from Jackson Lake Dam (Bureau of Reclamation) plus tributaries, so it stays runnable through summer. Check the reading above before you go. Source.
Below dams the river can rise suddenly and turn violent when releases start; stay out of tailrace areas and off the river outside scheduled windows unless you know the flow. Ranges are for experienced paddlers at the gauge shown; rapids change after floods, so scout and check for new wood. Wear a PFD, never boat alone, and follow the American Whitewater Safety Code.

How this rating works
Solunar theory says fish feed more when the moon is overhead or underfoot (major periods, about 2 hours) and around moonrise and moonset (minor periods, about 1 hour). On a lake or river there is no tide, so instead of tide changes we score the local conditions anglers watch: the barometric pressure trend, the wind, whether the river is steady, and the water temperature where it is measured.
| Base | every day starts at 1 | 1 |
|---|---|---|
| Sunrise / sunset | a period overlaps sunrise or sunset ±1 h: major +2, minor +1 (max 3) (Moon overhead × sunrise +2) | 2 |
| Moon phase | within 2 days of a new or full moon +2, within 4 days +1 (today: 4.6 days) | 0 |
| Local conditions | pressure 6 AM→6 PM: falling +2, steady or slowly rising +1, rising fast 0 · daytime wind 4–15 mph +1, over 20 mph (or gusts over 30) −1 · flow within ±15% in 24 h +1, rising over 25% −1 · water 55–75°F +1, below 45°F or above 85°F −1 (0 to 4 in total)

1–3 poor · 4–5 fair · 6–7 good · 8–10 excellent. Pressure and wind are the NOAA National Weather Service hourly forecast for this spot; the level/flow trend is the latest 24 hours of readings on this page; water temperature measured at this gauge. Days 2–7 score sun, moon, forecast pressure and forecast wind only (level and water temperature aren’t forecast). Solunar times are a rule of thumb, not a guarantee.
