Unknown river run
Unknown
The Unknown section of the river is approximately 6 miles long and features several challenging rapids and obstacles. One of the most notable obstacles is a steep and technical drop known as The Chute. Other rapids on this section of the river include Pinball, The Narrows, and The S-Turn.
Due to the technical nature of this section of the river, there are specific regulations in place to ensure the safety of all paddlers. All paddlers are required to wear a personal flotation device and a helmet while on the river. Additionally, it is recommended that paddlers have experience with class IV rapids before attempting this section of the river.
In conclusion, the Whitewater River run known as Unknown is a challenging and exciting section of the river that requires experience and skill to navigate safely. Understanding the ideal streamflow range, class rating, segment mileage, specific river rapids/obstacles, and specific regulations to the area is crucial for any paddler looking to tackle this section of the river.
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 Unknown 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.
About Unknown
What's the optimal flow for Unknown?
The optimal flow depends on the section and the craft. Check the Run Details panel for the linked gauge and current status.
How fresh is the cfs reading on this page?
The linked USGS streamgauge reports continuously (every 15 minutes); Snoflo refreshes throughout the day. Hover the streamflow sparkline to read individual datapoints.
What's the whitewater class?
See the Run Details panel for the class rating Snoflo tracks for this run. Class ratings change with flow -- a Class III at low water can become Class IV in high water.
Where do I put in / take out?
Tap Directions in the hero above to open driving directions to the put-in. For shuttle planning, check the Nearby Boat Launches panel and the river run operator's site.
Can I get alerts when flows hit the optimal range?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this run, set a discharge threshold, and you'll get a push the moment the gauge crosses.
