The St. Francis was not the first dam Mulholland constructed in the development of reservoirs in the Los Angeles area, but it would be the last. The dam was constructed to contain water to be used in the event of a drought. There would be enough water to accommodate the needs of Los Angeles throughout the dry period.
When full, the St. Francis Dam would hold back 12 billion gallons of water. Sadly, two years after the structure was completed, at a time of night when most of the unsuspecting community was sleeping, the dam collapsed, unleashing a gigantic flood of water, a hundred feet high, that would travel fifty miles, the Pacific Ocean. It is also the story of those who courageously responded to the disaster, taking part in the rescue and recovery of the flood victims. Many of their stories are related in this account of the disaster. The story describes the actions of the unsung heroes - those who tended to the bodies of those who did not survive the tragedy.
The St. Francis Dam collapse has been recognized as the greatest man-made disaster in California history. At least four hundred known people were killed in the flood, though many victims are still missing.
