thumbTujunga Wash is a stream in Los Angeles County, California. It is a tributary of the Los Angeles River, providing about a fifth of its flow, and drains about . It is called a wash because it is usually dry, especially the lower reaches, only carrying significant flows during and after storms, which usually only occur between November and April. The watershed includes Angeles National Forest and highly urbanized land in the northern portion of the Greater Los Angeles Area.
Tujunga Wash consists of two forks, both beginning in the San Gabriel Mountains. The upper portion of Big Tujunga Wash is called Tujunga Creek, or Big Tujunga Creek. It travels roughly east and several tributaries from the north and south join it as it flows to Big Tujunga Reservoir, formed by Big Tujunga Dam. Below the dam, the stream is called Big Tujunga Wash. It continues its westward flow, enters San Fernando Valley and is met by Little Tujunga Wash a mile before reaching Hansen Reservoir, which is formed (from [www.wikipedia.org](http://www.wikipedia.org/wiki/Tujunga_Wash).
