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.
