The Collapse That California Forgot

History & Society Technology Leadership & Corp Culture

The 1928 St. Francis Dam disaster killed 431+ people when 12 billion gallons of water surged through San Francisquito Canyon. Built by William Mulholland just two years earlier, the dam failed due to geological oversights and engineering flaws.

Best quote from The Collapse That California Forgot

The coroner's inquest recommended that the construction and operation of a great dam should never be left to the sole judgment of one man, no matter how eminent. This was a direct critique of the culture that had allowed Mulholland to operate with virtually no oversight.
