St. Francis Dam Disaster Site

The 185-foot concrete St. Francis Dam, part of the Los Angeles aqueduct system, stood 1½ miles north of this site. On March 12, 1928, the 185-foot high concrete dam collapsed just before midnight, sending 12½ billion gallons of water roaring down the Santa Clara River Valley 54 miles to the ocean. This was one of California’s greatest disasters: Over 450 lives were lost.

Plaque placed by the State Department of Parks and Receation in cooperation with Los Angeles Department of Water and Power, U.S. Forest Service and The Santa Clarita Valley Historical Society. Dedicated March 12, 1978.
