Today in Labor History March 12, 1928: The St. Francis Dam failed in Los Angeles, California, killing 431 people. It is the second deadliest disaster in California, after the 1906 earthquake, and one of the worst U.S. civil engineering disasters ever. A defective foundation and design flaws caused the failure. Yet, the inquest absolved chief engineer, William Mulholland, of all criminal responsibility, and he continued to earn a salary from the Bureau of Public Works (though his career was effectively ended). The authorities continued to find the remains of victims of the flood until the mid-1950s. Many of the victims were washed out to sea. Some washed ashore as far south as Mexico. Mulholland was also the designer of the 233-mile Los Angeles Aqueduct, which sucks water from the Owens Valley and is a major cause of the depletion of the fragile Mono Lake. As its water levels continues to decline, it threatens the world’s second largest gull rookery, home to up to 50,000 birds. The aqueduct’s construction, and the shady methods Mulholland used to acquire the water rights, led to the California Water Wars between L.A. County and Owens Valley farmers. Many of those same Anglo farmers (or their predecessors) usurped the land from Piute people during the 1863 Owens Valley Indian War, which was precipitated, in part, by the vast loss of human and cattle lives, and the displacements, caused by the Megaflood of 1861, which inundated much of the West, from Idaho and Oregon, down to northern Baja California. The corruption related to the construction of the aqueduct has been portrayed in the film Chinatown, and in the nonfiction book, “Cadillac Desert.”
