LOCATION AND DESCRIPTION:
Matilija Dam is located on Matilija Creek, a tributary to the Ventura River, near Ojai, in Ventura County. The dam is no longer functional as a water supply structure. It is a major impediment to the natural flow of the Matilija Creek, which traditionally supported a large population of Steelhead, a migratory fish related to the Salmon, and an endangered species. The study addressed the following issues: hydrology, hydraulics, dam safety, removal issues, water allocation, flood control, flood plain management, sediment removal, transport, beach nourishment, and environmental restoration. Authorized project features: Foster Park Wells; Live Oak Levee Meiners Oaks Levee; Sediment Highflow Bypass, Camino Cielo Bridge; Santa Ana Road Bridge; Desilting Basin; Arundo Removal and Matilija Dam Removal (Slurry Line, Earth Moving, Recreation Trail, Dam Removal).
