Clear Lake is a natural freshwater lake located in Lake County in the U.S. state of California, north of Napa County and San Francisco. It is the largest natural freshwater lake wholly within the state, with 68mi2 of surface area. Lakes have existed at the site for at least 2,500,000 years, possibly making it the oldest lake in North America.Known as the "Bass Capital of the West," Clear Lake supports large populations of bass, crappie, bluegill, carp and catfish. Two-thirds of the fish caught in Clear Lake are largemouth bass, with a record of 17.52 pounds. Clear Lake was most recently ranked by Bassmaster Magazine in 2016 as the #3 best bass lake in the United States and the #1 best bass lake on the West Coast. However, locals strongly recommend against eating the fish from Clear Lake because of potentially toxic levels of mercury. In addition to fish, there is abundant wildlife within the Clear Lake basin. There are year-round populations of ducks, pelicans, grebes, blue herons, egrets, osprey, and bald eagles, and the basin supports sizable populations of deer, bear, mountain lion, raccoon and other animals.The expansive, warm water of Clear Lake makes it popular for watersports, such as swimming, water skiing, wakeboarding, sailing, boat races, and jet skiing.
