The Whitewater River run in California stretches from the confluence with the South Fork Elk River to the headwaters in Sec. 21, T3N, R1E, H.M. The ideal streamflow range for this run is between 200 and 500 cubic feet per second (cfs). This is considered a Class III-IV run, with some sections reaching Class V during high water. The total distance of the run is approximately 11.5 miles.

The river has several notable rapids, including "The Chute," "Pinball," and "Meatgrinder." The Chute is a narrow, technical rapid with a steep drop that requires precise maneuvering. Pinball is a boulder garden with multiple channels that require quick decision-making and solid boat control. Meatgrinder is a long, continuous rapid with several large waves and holes.

There are no specific regulations for this area, but it is recommended that all boaters wear appropriate safety gear, including helmets and personal flotation devices. It is also important to respect private property and avoid disturbing wildlife.
