Castaic High School (CHS) is a high school in the unincorporated community of Castaic, California, in the Santa Clarita Valley. It is part of the William S. Hart Union High School District. The school officially opened on August 13, 2019.

Castaic Lake (Chumash: Kaštiq) is a reservoir formed by Castaic Dam on Castaic Creek, in the Sierra Pelona Mountains of northwestern Los Angeles County, California, United States, near the town of Castaic. The California Office of Environmental Health Hazard Assessment has issued a safety advisory for any fish caught in Castaic Lake and Castaic Lagoon due to elevated levels of mercury and PCBs.

Elderberry Forebay Dam is a dam located in the Sierra Pelona Mountains of northwestern Los Angeles County, California. The dam partitions Elderberry Forebay from Castaic Lake. It forms the headwater reservoir for Castaic Power Plant, a pumped-storage hydroelectricity generation facility. The dam was completed in 1974 as part of the California State Water Project.

Castaic Dam is an embankment dam in northwestern Los Angeles County, California, in the unincorporated area of Castaic. Although located on Castaic Creek, a major tributary of the Santa Clara River, Castaic Creek provides little of its water. The lake is the terminus of the West Branch of the California Aqueduct, part of the State Water Project. The dam was built by the California Department of Water Resources and construction was completed in 1973. The lake has a capacity of 325,000 acre-feet (401,000,000 m3) and stores drinking water for the western portion of the Greater Los Angeles Area.

Castaic ( ) (Chumash: Kaštiq; Spanish: Castéc) is an unincorporated community in the northwestern part of Los Angeles County, California, United States. As of the 2010 census it had a population of 19,015. For statistical purposes the Census Bureau has defined Castaic as a census-designated place (CDP).Tens of thousands of motorists pass through Castaic daily as they drive to or from Los Angeles on Interstate 5 (the Golden State Freeway). Castaic Lake is part of the California Water Project and is the site of a hydro-electric power plant. Castaic is 38 miles (61 km) northwest of Los Angeles Union Station and northwest of the city of Santa Clarita. The Castaic Range War went on for decades in the late 19th and early 20th centuries resulting in dozens of deaths before hostilities ceased in 1916.

Elderberry Forebay is a small reservoir in Los Angeles County, California, which serves as the pumping forebay of the Castaic Power Plant. It located at the upper end of the larger Castaic Lake and is separated from the lake by Elderberry Forebay Dam at its southern edge. Entering the northern end of the forebay is the west branch of the California Aqueduct, which connects the forebay to Pyramid Lake through the Angeles Tunnel.A component of the California State Water Project, the reservoir was partitioned from Castaic Lake in 1974 to store water for pumped-storage hydroelectricity generation. During on-peak energy-demand hours, water flows 7.5 miles (12.1 km) from Pyramid Lake through the Angeles Tunnel and then on to the turbines of the Castaic Power Plant, producing electricity. From there, the water flows into Elderberry Forebay. During off-peak hours (including nighttime and Sundays), water is pumped from the forebay, back through the tunnel and into Pyramid Lake.

Hasley Canyon is a census-designated place in the Sierra Pelona mountains of Los Angeles County, California. Hasley Canyon sits at an elevation of 1,765 feet (538 m). The 2010 United States census reported Hasley Canyon's population was 1,137.

99 Oaks is an archaic placename of the Santa Clarita Valley, Los Angeles County, California in the United States. The location was mainly a rest stop between Castaic and Castaic Junction in what was then a fairly remote location along Old Highway 99. Otis and Macy Andrews opened the 99 Oaks Café in 1936. Circa 1950, 99 Oaks had a service station and a café. The name 99 Oaks was later used for buildings nearby, such as 99 Oaks Auto Court in Mint Canyon, 99 Oaks Cabins in Castaic, and the 99 Oaks Car Lot in Newhall. What little there was of 99 Oaks "mostly disappeared" when Route 99 was replaced by Interstate 5 in 1968.

Castaic Power Plant, also known as the Castaic Pumped-Storage Plant, is a seven unit pumped-storage hydroelectric plant, operated by the Los Angeles Department of Water and Power, which provides peak load power from the falling water on the West Branch of the California State Aqueduct. It is a cooperative venture between the LADWP and the Department of Water Resources of the State of California. An agreement between the two organizations was signed on September 2, 1966, for construction of the project.

The Angeles Tunnel is a 7.2-mile-long (11.6 km), 30-foot-diameter (9.1 m) water tunnel located in the Sierra Pelona Mountains in Los Angeles County, California, about 50 miles (80 km) north of Los Angeles. It was constructed between 1967 and 1970 as part of the California State Water Project and serves as the final leg of the west branch of the California Aqueduct, which carries Northern California water to Southern California residents.The tunnel also supplies water to the adjacent Castaic Power Plant, a pumped-storage hydroelectricity generation facility. To facilitate power generation, the tunnel's flow is bidirectional. During on-peak energy-demand hours, water flows downhill through the tunnel, starting at an elevation of 2,572 feet (784 m) in Pyramid Lake, and then falling over 1,000 feet (300 m) to the turbines of the Castaic Power Plant at 1,519 feet (463 m). The water is then stored in the Elderberry Forebay, adjacent to Castaic Lake. During off-peak hours, water is pumped uphill through the tunnel in the opposite direction from Elderberry Forebay and returned to Pyramid Lake. This operation reduces the energy cost of moving water along the California Aqueduct.

Val Verde () (Spanish for "Green Valley") is an unincorporated community in the southeastern Topatopa Mountains foothills, and in northwestern Los Angeles County, California. The unincorporated community of Valencia (Newhall Ranch) is southeast, and the city of Santa Clarita is east of the community. Its population was 2,468 at the 2010 census, up from 1,472 at the 2000 census. For statistical purposes the Census Bureau has defined Val Verde as a census-designated place (CDP).

North County Correctional Facility (NCCF) is a Los Angeles County jail, run by the Los Angeles County Sheriff's Department. Located approximately 40 miles (64 km) northwest of downtown Los Angeles, it is one of four jails located within the Pitchess Detention Center (named after former Sheriff Peter J. Pitchess), in Castaic, California. The facility's construction began in 1985, and it was formally dedicated on March 1, 1990 by then Sheriff, Sherman Block, and the President of the United States, George H. W. Bush. NCCF consists of five jails within the same facility, and it has an inmate population of about 3,800. It can provide for disciplinary segregation and clinic-level medical treatment. The facility is commonly referred to as the "Flagship"; it was designed and constructed to be cost-efficient with regard to the ratio of staff members to inmates and vocational productivity. NCCF has a ratio of ten inmates to each staff member. The facility features educational, vocational and counseling programs. These programs have been designed to assist the facility's inmates in becoming self-sufficient within the law.
