The only free-flowing non-tidal stretch of the Columbia River. The Hanford Reach runs 51 miles through the former Hanford nuclear reservation, where decades of restricted access accidentally preserved the last wild fall Chinook salmon run on the Columbia. The massive river flows past White Bluffs and through shrub-steppe desert in a setting unlike anything else in the Pacific Northwest.
River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
