Browns Canyon Wash, also known as Browns Canyon Creek, is a tributary of the Los Angeles River in the Santa Susana Mountains of Los Angeles County and across the western San Fernando Valley of Los Angeles, California.
Course
The stream begins as a free-flowing stream in Browns Canyon of the eastern Santa Susana Mountains, partially within Michael D. Antonovich Regional Park at Joughlin Ranch. It runs along Browns Canyon Road, which leads to the Cold War Oat Mountain Nike missile base site, on the border of the Chatsworth and Porter Ranch communities.
After passing under the State Route 118 (Ronald Reagan Memorial Freeway), it is then encased in a concrete flood control channel, traveling southwards through Chatsworth, Canoga Park, and Winnetka. Its confluence with the Los Angeles River is just west of Mason Avenue and north of Vanowen Avenue. The channel walls near Winnetka were damaged in the 1994 Northridge earthquake.
The wash features an equestrian and bicycle path along its eastern bank in Chatsworth.
