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.
