The largest dam removal project in U.S. history was completed Oct. 2 on the Klamath River in Southern Oregon and Northern California. Four dams were taken out, allowing adult salmon to swim all the way up the Klamath River from the Pacific Ocean and into more than 400 miles of newly reopened habitat. OPB cinematographer Brandon Swanson collected video footage of the dam sites before and after the removal operation. The video above includes before and after shots of all four dams. … The video also includes before-and-after shots of a site along Iron Gate reservoir, where an algae bloom had turned the stagnant lake green in 2022, and a site along Northern California’s Copco Lake reservoir, where a community of about 100 people lives.
