The Whitewater River Run in California from Centerville Flat to Hangman's Bridge is an exhilarating adventure for experienced white-water rafters. The ideal streamflow range for this river is between 500 and 1,200 cubic feet per second (cfs), which is usually available from late April to early June.

This stretch of the river is rated as Class III-IV, with a total segment mileage of approximately 10 miles. Rafters can expect to encounter specific river rapids, such as "Rock Crusher," "Triple Threat," and "Suck and Swallow." The most challenging rapid on this section of the river is known as "Hangman's Bridge," which requires precise navigation and quick reflexes to make it through safely.

In addition to the rapids, rafters must be aware of specific regulations in the area. It is mandatory to wear a personal flotation device (PFD) at all times, and all rafts must have a throw rope and a whistle on board. Rafters should also be mindful of the limited parking availability and the need to obtain a permit before accessing the river.
