Clearlake Highlands is a former unincorporated community now incorporated in Clearlake, in Lake County, California. It is located on the north shore of the southeast end of Clear Lake, just south of the village of Clearlake Park, 15 miles (24 km) east-southeast of Lakeport, at an elevation of 1348 feet (411 m).Clearlake was originally settled by Americans in the late 1860s. Prior to settlement by Americans the area was inhabited by Pomo Indians. Their artifacts and grave sites have been found along Cache Creek at the Southern city limit as well as the area around Borax Lake in the northwest portion of the city. Clearlake remained a farming and ranching community until the 1920s when it became a resort destination along with other areas in Lake County. A large portion of the area which was to become the City of Clearlake was subdivided in 1925. Most of the city lots are only 50' by 100' feet and none of the infrastructure was established at the time of subdivision. A majority of the roads were never paved and some only exist on paper. Clearlake has historically depended on tourism as its main industry with the attraction being Clear Lake. This has been a boom or bust cycle over the decades depending on several factors. Clear Lake is California's largest natural lake and boasts itself as being "The Bass Capital of the West".

The Clear Lake AVA is an American Viticultural Area located in Lake County, California. Half of the area contained within the boundaries of the AVA is Clear Lake, the largest body of freshwater in the state of California, and the namesake for the county. The moderating influence of the lake on the surrounding area results in a climate with less diurnal variation in temperature than surrounding areas. Elevations range from 1,300 feet to well over 3,000 feet. Clear Lake AVA is one of the coolest climates in California, which has led to success with grape varietals like Sauvignon blanc.

For other places with the same name, see Rattlesnake Island (disambiguation).Rattlesnake Island is an island located on Clear Lake in Lake County, northern California. Its land area is nominally 53 acres (210,000 square meters), but may vary significantly as lake levels rise and fall. It is 500 feet (150 meters) offshore from the north shore of the eastern arm of Clear Lake, the site of the Elem Indian Colony. There is evidence of Native American activity on the island, possibly dating back as much as 8,000 years, although little archaeological work has been conducted. This site is connected with the prehistoric Post Pattern, and has probably been used by the Southeastern Pomo throughout prehistoric times. The Elem Pomo Colony have claimed the island to be their place of origin, and a political and religious center. A history of ownership disputes dates as far back as the late nineteenth century. Due to a controversial 1949 U.S. court decision, the Elem Pomo tribe lost legal control of 80,000 acres (32,375 hectares) of its ancestral land, including the island. At present, legal title to the island is held by a Bay Area businessman, John Nady (founder of Nady Systems, Inc.) His 2003 attempt to obtain permits to construct a log cabin on the island was challenged by Elem Indian Colony members but eventually granted. John Parker, a local archaeologist, petitioned the federal government to add the island to the National Register of Historical Places. John Nady is currently developing a sustainable vacation home there with solar power and resident livestock.
