The ideal streamflow range for this section is between 1,000 and 5,000 cfs, as anything lower will result in scraping and anything higher is considered dangerous.
This section stretches for 28 miles, starting at the Headwaters and running all the way to the Wilderness Boundary. Along the way, there are numerous rapids and obstacles to navigate, including Big Bend, S-Turn, and Box Canyon. These rapids range in difficulty, with some requiring precise maneuvering and others simply requiring a strong paddle.
In order to protect the natural beauty and integrity of the river, there are specific regulations in place for this area. These include a limit on the number of permits issued per day, as well as restrictions on camping and fires. It is important for those planning to run this section of the Whitewater River to familiarize themselves with these regulations and to obtain the necessary permits before embarking on their journey.
