Summary

This 6-mile segment is rated as a class III+ run with some challenging rapids and obstacles along the way. The ideal streamflow range for this segment is between 500 and 1,500 cfs.

Some of the notable rapids and obstacles in this section of the river include the Punchbowl, a large hole that can be difficult to navigate, and the entrance to the Narrows, a tight and technical section of the river. Paddlers should be aware of strainers and sweepers along the way, which can be dangerous at high water levels.

In terms of regulations, paddlers should obtain a Montana fishing license if they plan to fish on the river. There are no specific regulations for whitewater paddling, but it is always important to practice Leave No Trace principles and respect private property along the riverbanks.
