Removal of four aging hydroelectric dams on the mainstem Klamath River, which flows through parts of Southern Oregon and Northern California has been the subject of national attention for nearly two decades. Over 40 organizations, irrigation districts, and tribes support taking the dams out, and Tribal leadership has been a central component of the dam removal effort. The Yurok, Karuk and Klamath River Tribes have led the effort to restore part of their cultural heritage and subsistence fishing for salmon and lamprey. Removal of the four Klamath River dams will be the largest dam removal project in the history of the United States and the largest salmon restoration project ever.

Land Acknowledgment

The Klamath dams are on the ancestral lands of the Yurok, Karuk, and Klamath tribes. The Yurok reservation is located at the mouth of the Klamath River and is today one of the largest tribal reservations in California. The Karuk tribe lives in its ancestral homelands along the middle section of the Klamath River. The Klamath tribes are located in southern Oregon in the Klamath basin, above the dams.
