The Klamath River Hydroelectric Project was a series of hydroelectric dams and other facilities on the mainstem of the Klamath River, in a watershed on both sides of the California-Oregon border. The infrastructure was constructed between 1903 and 1962, the first elements engineered and built by the California Oregon Power Company ("Copco").
Water was first made available May 22, 1907. The Clear Lake Dam was completed in 1910, the Lost River Diversion Dam and many of the distribution structures in 1912, and the Anderson-Rose Diversion Dam (formally Lower Lost River Diversion Dam) in 1921. The Malone Diversion Dam on Lost River was built in 1923 to divert water to Langell Valley.
