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.
