Onion Creek river run
Onion Creek
The segment mileage for Onion Creek is 9.5 miles, starting at Fisher Towers and ending at Utah State Route 128. The river is known for its technical rapids and obstacles, including the "Onion Creek Slide," a steep and narrow chute that requires precise maneuvering.
There are specific regulations to the area, including a permit requirement to enter Fisher Towers and a limit on the number of vehicles allowed to park at the put-in. It is also essential to practice Leave No Trace principles, as the area is fragile and susceptible to damage.
Overall, Onion Creek offers a thrilling whitewater experience and is recommended for experienced paddlers who are comfortable with class III-IV rapids. It is essential to check the streamflow levels before attempting the run and to adhere to all regulations to ensure the safety of both yourself and the environment.

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 Onion Creek 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.
