The Klamath River Renewal Corporation has filed its “Definite Plan” with the Federal Energy Regulatory Commission to remove four hydroelectric dams on the lower Klamath River. Four hydroelectric dams blocking fish passage along the lower Klamath River in southern Oregon and northern California are slated for removal under a “Definite Plan” filed with the Federal Energy Regulatory Commission. The dams — J.C. Boyle, Copco No. 1, Copco No. 2 and Iron Gate — were built between 1911 and 1962, and are currently operated by PacifiCorp with a combined generation capacity of 169 megawatts.
