Summary
The ideal streamflow range for this segment is between 1,500-4,500 cubic feet per second (cfs), which provides Class III-IV rapids. The total segment mileage is 7.2 miles, with a gradient of 87 feet per mile. The rapids on this segment include Corkscrew, Rattlesnake, and Kautz Creek Falls.
Specific regulations to the area include a required permit for all commercial and private rafters, which can be obtained through the National Park Service. Additionally, all boaters are required to wear appropriate personal flotation devices (PFDs) and follow Leave No Trace principles. The area is also designated as a Wild and Scenic River, which means that certain restrictions apply, such as no motorized boats and limited group size.
It is important to note that the Whitewater River Run can be dangerous and should only be attempted by experienced whitewater paddlers. Water levels can change rapidly, and there are many hazards, including undercut rocks and strainers. It is recommended that boaters scout the rapids before attempting them and that they paddle with a group of experienced paddlers.
