About this run

Johnson Creek To Confluence With Hunter Creek

The Johnson Creek to Confluence with Hunter Creek section of the Whitewater River in Idaho is a popular destination for kayakers and rafters. The ideal streamflow range for this section is between 500 and 1,500 cubic feet per second (cfs), with the best conditions occurring in the spring and early summer. The segment mileage for this stretch is approximately 22 miles, with class ratings ranging from Class II to Class IV.

The river features several notable rapids and obstacles, including Radio Wave, a Class III rapid with a large wave train, and Staircase, a Class IV rapid with steep drops and technical maneuvering. Other notable obstacles include House Rock, a large boulder in the middle of the river that requires careful navigation, and Boulder Slide, a steep and rocky section of the river with multiple drops.

There are several regulations in place for this section of the river. All boaters are required to have a permit, which can be obtained from the Forest Service. Additionally, all boaters must wear a properly fitting personal flotation device (PFD) and carry a whistle or other audible signaling device. Camping is allowed at designated sites along the river, but fires are only allowed in established fire rings.

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
