About

Class II-III(IV) water drops through BLM-managed canyon country on the Grande Ronde's final 38 miles from the Oregon-Washington state line to the Snake River. The parenthetical IV rating indicates some rapids can push harder depending on flows, though specific optimal ranges aren't established for this remote section. USGS gauge 13333000 tracks conditions, but paddlers typically run this as a multi-day wilderness trip where scouting and self-sufficiency matter more than precise flow windows. The bureau manages this corridor as undeveloped public land, maintaining the wild character that draws boaters to the Snake River confluence.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
