Summary

The Whitewater River Run Source To End Of Forest Road in Wyoming is a popular destination for whitewater enthusiasts. The ideal streamflow range for the river is between 1,000 and 3,000 cubic feet per second (cfs), which usually occurs in the spring and early summer. The river is rated as a Class III-IV run, with some Class V sections, and covers a total of 21 miles.

The first few miles of the run are relatively easy and consist of mostly Class II rapids. However, the river quickly becomes more challenging with several Class III and IV rapids, including "The Notch," a narrow and technical rapid that requires precise maneuvering. The most difficult sections of the river are located towards the end of the run, with several Class V rapids, such as "The Narrows" and "The Wall."

In terms of regulations, the Whitewater River Run is located within the Shoshone National Forest, and a permit is required to run the river. Additionally, all participants must wear a personal flotation device (PFD) and helmets are strongly recommended. The river is also subject to seasonal closures to protect fish spawning areas and other natural resources.
