Four hydroelectric dams on the Klamath River were demolished by October 2024, following almost two decades of negotiations between local representatives, tribes, conservation groups and the utility company operating the dams. This enabled salmon migration to the Upper Klamath Basin for the first time in over 100 years, and established new ...
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.
Copco Number 1 Dam (National ID CA00323) is a gravity dam 415 feet (126 m) long and 132 feet (40 m) high, with 19.5 feet (5.9 m) of freeboard. PacifiCorp owned the dam prior to its transfer to the Klamath River Renewal Corporation in 2022. [18] The dam was demolished in September 2024 as part of the Klamath River Renewal Project. [19] [20]
The dam blocked the Klamath River to create the Iron Gate Lake Reservoir. It was the lowermost of a series of power dams on the river, the Klamath River Hydroelectric Project, operated by PacifiCorp. It also posed the first barrier to migrating salmon in the Klamath. The Iron Gate Fish Hatchery was placed just after the dam, hatching salmon and ...

The Klamath River begins in the high desert of southern Oregon, and the average annual flow at Keno (about 20 miles below Upper Klamath Lake) is just over 1.1 million acre-feet (1.4 km 3). A Klamath Diversion at this point would be simple–an aqueduct running south to Shasta Lake on the Sacramento River—but the flow here is not enough to ...
The John C. Boyle Dam is one of four on the Klamath River that was removed under the Klamath Economic Restoration Act. [5] As of February 2016, the states of Oregon and California, the dam owners, federal regulators and other parties reached an agreement to remove all four dams by the year 2020, pending approval by the Federal Energy Regulatory ...
