Bass Lake (Madera County, California)
Bass Lake, situated in Madera County, California, within the  Sierra National Forest and approximately 14 mi (23 km) south of Yosemite National Park, is a popular recreational area. The lake, formed by the Crane Valley Dam on Willow Creek, a tributary to the San Joaquin River, spans about four miles (6.4 km) in length and one-half mile (0.80 km) in width. Constructed in 1910 (1910) by Pacific Gas and Electric, the 145 ft (44 m) concrete gravity dam generates hydro-electric power through controlled releases. The lake supports a diverse ecosystem, including species such as black bears, mule deer, bald eagles, and Great blue herons, along with a variety of fish species. Historically, the Mono Native Americans inhabited Bass Lake until the California Gold Rush.
