The San Gabriel River flows 60.6 miles through Los Angeles County. Its watershed is deep in the San Gabriel Mountains within the Angeles National Forest north of the Los Angeles Basin. The river flows across the San Gabriel Valley south through Downey, Norwalk, Bellflower, Cerritos, Cypress, Long Beach, Seal Beach, and then into Alamitos Bay and the Pacific Ocean. The San Gabriel River watershed is a habitat for the endangered Steelhead trout and the Mountain Yellow-Legged frog which was once threatened with extinction. The San Gabriel River basin was occupied by the Tongva People for thousands of years before the area was claimed by Spain and later by Mexico.

 

Morris Dam and Reservoir

Samuel B. Morris Dam

The Morris Dam is a concrete gravity dam, 245 feet high and 750 feet long, completed in 1934 in the Angeles National Forest, north east of Azusa, California in northern Los Angeles County. The dam, built on the San Gabriel River, impounds the Morris Reservoir which has a surface area of 417 acres and is approximately three miles long. During World War II, and until the early 1990s, the reservoir was used to test navel weapons. The military facilities have been removed except for several large concrete foundations which are visible from State Route 39.

 

San Gabriel Dam

The San Gabriel Dam, completed in 1939, is a rock-fill dam on the San Gabriel River within the Angeles National Forest in northeastern Los Angeles County approximately 4.9 miles north of Glendora. The 315 foot high, 1,520 foot long dam created the 525-acre San Gabriel Reservoir. The dam provides hydroelectricity for the San Gabriel valley section of eastern Los Angeles County and flood control. It is stocked with rainbow trout, bluegill, carp, catfish, smallmouth bass, brown trout, and bream. Fishing is permitted with a license.

Southern California Watersheds

A watershed is an area of land that collects water whenever it rains or snows and from irrigation. Through gravity, water channeled into soils, groundwater, creeks, and lakes, drain into larger bodies of water and eventually to the ocean. Due to the large volume of storm water, it cannot be treated before it reaches the ocean. Since we all live in a watershed, we can all help in keeping our area free of harmful chemicals and other waste.

 

Tongva Indian Villages

Tongva Indian Villages were located in the Los Angeles Basin for thousands of years. These villages were located near and around the ever changing Los Angeles River, San Gabriel River, Santa Ana River, and the coastal areas.
