Flow is set by Flaming Gorge Dam releases (Bureau of Reclamation). Gates of Lodore trips need a Dinosaur National Monument permit. 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.
