Tulare Lake, in the southern San Joaquin Valley in California, United States, had at various points in its history prior to 1880 an archipelago in the southern portion of the lake. Since the lake shore largely varied with the season (from rainfall and snowmelt from the Sierras), there is a wide variety of names attested for the islands. Today, these former islands make up the Sand Ridge in Kings County and are the traditional territory of the Wowol people.
