Headwaters, Sec. 13, T18n, R10w To Forest Boundary, Sec. 6, T17n, R7w
There are specific river rapids and obstacles to be aware of on this run. One of the most challenging rapids is known as Hell's Half Mile, which is a Class IV rapid with large waves and a narrow chute. Other notable rapids include House Rock, The Maze, and Fang. It is important for paddlers to be experienced and skilled in navigating rapids and avoiding obstacles.
There are also specific regulations in place for this area. The use of motorized watercraft is not allowed, and all paddlers must wear a personal flotation device. Additionally, camping is only allowed in designated areas, and all fires must be contained within established fire rings. It is important for visitors to familiarize themselves with all regulations before embarking on their river trip.
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.

Campgrounds
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 Headwaters, Sec. 13, T18n, R10w To Forest Boundary, Sec. 6, T17n, R7w 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.
