The Huasna River is a stream in the Central Coast region of California, and is a tributary of the Cuyama River. It is formed by the confluence of Trout Creek and Stony Creek, which originate along the crest of the Santa Lucia Range in the Los Padres National Forest. It flows south, past the community of Huasna and the Huasna Valley before reaching Twitchell Reservoir, which is created by a dam along the Cuyama River.
The Central Coast is an area of California, United States, roughly spanning the coastal region between Point Mugu and Monterey Bay. It lies northwest of Los Angeles County and south of San Francisco and San Mateo counties. Six counties make up the Central Coast: from south-to north, Ventura, Santa Barbara, San Luis Obispo, Monterey, San Benito, and Santa Cruz.
California is a state in the Pacific Region of the United States. With 39.6 million residents, California is the most populous U.S. state and the third-largest by area. The state capital is Sacramento. The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, and the country's second most populous, after New York City. California also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs.
The Cuyama River is a 118-mile-long (190 km) river in southern San Luis Obispo County, northern Santa Barbara County, and northern Ventura County, in the U.S. state of California. It joins the Sisquoc River forming the Santa Maria River. The river's name comes from an Indian village named for the Chumash word kuyam, meaning "clam" or "freshwater mollusk".
Like most other streams in this part of California, the Huasna River is usually dry, with significant flows only during the winter and early spring. During rare high water levels of Twitchell Reservoir, the lower part of the Huasna Valley may be flooded. [3]
