Lake County is a county located in the north central portion of the U.S. state of California. As of the 2020 census, the population was 68,163. The county seat is Lakeport. The county takes its name from Clear Lake, the dominant geographic feature in the county and the largest non-extinct natural lake wholly within California. (Lake Tahoe is partially in Nevada; the Salton Sea was formed by flooding; Tulare Lake was drained by the agricultural industry.)
