• Klamath Dams


Copco #1, Copco #2, Iron Gate and J.C. Boyle (in Oregon) are four aging hydroelectric dams on the mainstem Klamath River, which flows through parts of Southern Oregon and Northern California. Removal of the dams has been the subject of national attention for nearly two decades. Over 40 organizations, irrigation districts, and tribes support taking the dams out. Tribal leadership has been a central component of the dam removal effort. The Yurok, Karuk and Klamath Tribes have led the effort to restore part of their cultural heritage and subsistence fishing for salmon and lamprey.
