Bull Creek is a 〔U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. (The National Map ), accessed March 16, 2011〕 tributary of the Los Angeles River in the San Fernando Valley of Los Angeles County, California. The creek rises in Bull Canyon on Oat Mountain. After leaving its canyon, it is encased in a concrete flood control channel, wherein it runs south from Granada Hills though North Hills, Van Nuys (including its airport), and Lake Balboa. South of Victory Boulevard, the river reverts to a free-flowing stream and joins the Los Angeles River inside the Sepulveda Dam Recreation Area. This section has recently been restored under a federally funded ecosystem restoration project, in part to protect the important riparian habitat. In 1971, on the morning of the Sylmar earthquake, residents of Granada Hills, Northridge, North Hills, and Van Nuys who were living between Balboa Boulevard and the San Diego Freeway were evacuated after the Van Norman Dam nearly broke. However, a great flood down the banks of Bull Creek was averted. ==Crossings and tributaries== From mouth to source (year built in parentheses):〔(【引用サイトリンク】title=National Bridge Inventory Database )〕 *Road in Lake Balboa Park *Metro Orange Line *Bicycle path *Victory Boulevard (1955) *Haynes Street (Bridge ) *Vanowen Street (1954) *Sherman Way (1954) *Saticoy Street (1954) *Stagg Street (1955) *Road in Van Nuys Airport *Taxiway in Van Nuys Airport *Roscoe Boulevard (1955) *Railroad: Union Pacific Coast Line *Parthenia Street (1955) *Nordhoff Street (1955) *Hayvenhurst Avenue & Plummer Street (1974) *Grenada Channel enters *Lassen Street (1973) *Mayall Street (Bridge ) *Devonshire Street (1956) *Chatsworth Street (1956) *Celtic Street (1976) *Bull Creek Canyon Channel Bridge carrying State Route 118 Ronald Reagan Freeway - twin bridges (1994) *San Fernando Mission Road (1962) *John F.
