Canoga Park (formerly known as Owensmouth) is a section of the San Fernando Valley region of Los Angeles, California, United States about 25 miles (40 kilometers) northwest of Downtown Los Angeles. It is bordered by Woodland Hills on the south, West Hills on the west, Chatsworth on the north, and Winnetka on the east.
Bell and Dayton Creeks flowing from the Simi Hills, and Arroyo Studio City (Studio City Creek) from the Santa Monica Mountains are several of the headwaters of the Los Angeles River that originate in the western San Fernando Valley that flow through Canoga Park. The Los Angeles River itself begins at the confluence of Studio City Creek and Bell Creek behind Canoga Park High School. These and other small creeks supply stormwater and suburban runoff water to the Los Angeles River, and several are considered year round creeks. Although the creeks are now channeled and run within concrete walls, they do form a significant urban wildlife landscape and contribute to the population of indigenous wildlife left within the San Fernando Valley.
