About

Class III-IV drops through 100 miles of designated Wild & Scenic corridor make the Middle Fork Salmon one of the West's premier multi-day wilderness runs. At 1,454 CFS average, with an optimal window from 725 to 2,200 CFS, the river demands technical boat handling through continuous whitewater that rarely lets up. Forest Service permits control access to this roadless drainage, where commercial outfitters and private boaters alike commit to week-long expeditions through country that remains much as it was before settlement. USGS gauge 13309220 tracks the flows that determine whether you're looking at a technical low-water run or a high-volume pushy descent through the same granite canyon system.
