National Wild & Scenic River (partial) · Klamath Dam Removal — Largest in U.S. History (2024)

The site of the largest dam removal in U.S. history — four Klamath River dams were removed in 2024, reopening 400 miles of salmon habitat for the first time in over a century. The Klamath flows 257 miles from southern Oregon to the Pacific through remote Northern California canyon country. Class I–IV whitewater, world-class steelhead, and one of the most dramatic river restoration stories in American history.

Data Quality

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.
