Santa Margarita River
The Santa Margarita River is a short
intermittent riveron the Pacific coast of southern Californiain the United States, approximately 50 mi (80 km) long. One of the last free-flowing rivers in southern California, it drains an arid region of the Coast Rangesbetween Los Angeles and San Diego at the southern end of the Santa Ana Mountains.
It is formed in southwestern Riverside County, east of Interstate 15 15 mi (25 km) ENE of Temecula, from the confluence of
Temecula Creekand Murrieta Creek. It flows southwest past Temecula, through the Temecula Canyonat the south end of the Santa Ana Mountains. Along its lower 10 mi (16 km) the river forms a large floodplain as it crosses Camp Pendleton Marine Corps Base. It enters the Gulf of Santa Catalinaon the Pacific approximately 3 mi (5 km) northwest of Oceanside.
Approximately 4334 acres (17.54 km²) of the middle course of the river in Temecula Canyon are owned and managed by
San Diego State Universityas the Santa Margarita Ecological Preserve. In addition, The Nature Conservancyhas been active in acquiring land along the river for conservation.
The river was the site of several attempts to build railroads in the 1880s. During much of the 20th century the river was the subject of a long-running water rights battle between the
United States Navyand the Fallbrook PUD. The conflict was resolved in 1967 and the following year both entities proposed to jointly construct dams on the river. The proposal was abandoned in 1984 due to environmentalist opposition.
