Boise, S. Fork - 2. Danskin Bridge to Neal Bridge (near Arrowrock Reservoir) (ID)
Buffalo Creek (second of three named rapids) is a Class IV due to the length of the rapid. A failed roll at the entrance would result in a long and rocky swim with possible pin hazards.
Enter center/left, catch the eddy on river left after the first couple of moderate hits, then continue down the left side, picking your way between holes and rocks (1200 CFS).
Easily scoutable from pool on river left. Also a good place for lunch.
Always look for wood on this section.
