The Nez Perce Fork Bitterroot River is a popular whitewater river run in Montana. The ideal streamflow range for this run is between 100 and 600 cubic feet per second (cfs), with peak flows occurring in May and June due to snowmelt. The run is rated Class II-III, with occasional class IV rapids during high water.
The segment mileage of the run is approximately 20 miles, starting at Sec. 26, T1S, R22W and ending at Painted Rocks Dam, Sec. 26, T1S, R22W. The river runs through a scenic, forested canyon with views of the Bitterroot Mountains.
Specific river rapids and obstacles include the "Roaring Lion" rapids, a series of class III rapids with boulder gardens and strong currents. Other notable rapids include "Little Willow" and "Kootenai". The run also features several shallow rocky sections that require careful navigation.
Regulations for the area include a requirement for a Montana Fishing License, as well as restrictions on camping and campfires. Additionally, boaters are required to wear personal flotation devices (PFDs) at all times.
