Copco Lake is an artificial reservoir located on the Klamath River in Siskiyou County, California, near the Oregon border. Created in 1922 by the construction of Copco Number 1 Dam, this fishing destination is home to a variety of game fish species and offers excellent angling opportunities throughout much of the year. With its scenic surroundings and diverse fishery, Copco Lake provides a rewarding experience for anglers of all skill levels, particularly those targeting bass, trout, and panfish species. The lake's optimal fishing periods are during the spring and fall months when water temperatures typically range from 50 to 70 degrees Fahrenheit.
