Copco Lake

Siskiyou County, United States

Copco Lake was an artificial lake on the Klamath River in Siskiyou County, California, near the Oregon border. The lake's waters were impounded by the Copco Number 1 Dam, which was completed in 1922 as part of the Klamath River Hydroelectric Project. The dam was breached in January 2024 as a component of the Klamath River Renewal Project following decades of activism from the Un-Dam the Klamath movement. The dam structure was fully removed by early October 2024.
