Eastside Tributary #1

The Eastside Tributary #1 of the Whitewater River in Utah is a beautiful and challenging 11-mile stretch of river that is popular among whitewater enthusiasts. The ideal streamflow range for this section of the river is between 500 and 1500 cfs. The class rating for this segment is class III-IV, which means that it is suitable for experienced kayakers and rafters who are comfortable navigating through challenging rapids with strong currents and significant obstacles.

The section of the river includes numerous rapids and obstacles that challenge even the most experienced paddlers. Some of the most difficult rapids on this stretch include Pinball, S-Turn, and The Elbow.

There are specific regulations that apply to this section of the river. For example, all boaters are required to wear a personal flotation device (PFD) at all times while on the water. Additionally, boaters are not allowed to camp or build fires along the riverbank.

Overall, the Eastside Tributary #1 of the Whitewater River is a challenging and exciting section of river that offers experienced whitewater enthusiasts an opportunity to test their skills and push their limits.

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 Eastside Tributary #1 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.
