Upper Green River
Some of the notable rapids and obstacles on this run include the S.O.B. Rapid, which is a Class IV rapid that requires precise maneuvering. The Little Hole Rapid is another Class IV rapid that requires paddlers to navigate around large boulders. Other notable rapids include Gremlin, Skull, and Corkscrew.
In terms of regulations, the Upper Green River is managed by the Bureau of Land Management and requires a permit for all commercial and private use. Additionally, all paddlers are required to wear a personal flotation device while on the river. Overall, the Upper Green River provides a challenging and exciting whitewater experience for experienced paddlers.
Plan your run down to the hour
Same weather feed Snoflo's iOS app uses -- updated continuously from NOAA / yr.no. Watch the precipitation column on the meteogram; rain ahead of a run typically lifts flows 12-48 hours later depending on the basin.

Whitewater safety
- Check the flow before you run
- Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
- Know your skill ceiling
- Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
- Wear the right gear
- Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
- Scout, set safety, and run with a team
- Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
- Respect the river
- Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.
Set push alerts in the Snoflo app
Save Upper Green River as a favorite, set a discharge threshold (e.g. "alert me when flow hits 600 cfs"), and the iOS app pushes the moment the linked gauge crosses.
