Clear Lake in Lake County, California, stands as the largest natural freshwater lake wholly within the state, encompassing 68 square miles of surface area with over 100 miles of shoreline. Known as the "Bass Capital of the West," this ancient lake has sustained fishing and wildlife for nearly 500,000 years, making it one of North America's oldest lakes. The moderately shallow waters average 27 feet in depth with a maximum of 60 feet, creating ideal conditions for a remarkably productive fishery. With warm water temperatures averaging 76°F in summer and 40°F in winter, Clear Lake supports exceptional fish populations that have earned it recognition as the #3 best bass lake in the United States and #1 on the West Coast according to Bassmaster Magazine.
