The 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 12⅓ billion gallons of water roaring down the Santa Clara River valley 54 miles to the ocean. This was one of California's greatest disasters, and over 450 lives were lost.
