For thousands of years, the Klamath River in Northern California was home to one of the continent’s great salmon runs, creating abundance for the native Yurok Tribe … until a series of dams and a century of extraction nearly destroyed it. Indigenous advocate Amy Bowers Cordalis helped lead the fight to take down those dams — the largest removal of its kind in US history. She offers a roadmap for communities everywhere working to protect and restore the places they call home.
