Copco Lake is a beautiful lake located about 30 miles northeast of Yreka, California just south of the Oregon border. It is an artificial lake formed in 1917 upon the completion of the Copco Dam on the Klamath River. It has a surface area of 1000 acres and contains 77,000 acre-feet of water. At one time the river just below the dam was 130 feet above its present bed and water backed up 5 miles and formed a natural lake which varied in width and was a mile at its widest part.
The elevation of the lake is about 2700 feet. The area around the lake was subdivided in the 60's and there are currently about 150 homes around the lake. The Fire Stations, the Community Center and the Copco Lake Store were built in the 70's.
