St. Francis Dam flood
Posted: Sun Dec 17, 2017 8:18 pm
A flood I hadn't heard about: A friend posted on Facebook a picture captioned, "View yesterday from above San Francisquito Power Plant #2, north of Santa Clarita, CA, & just south of the ruins of the St. Francis Dam. 12.5 billion gallons of water crashed through here just before midnight on March 12, 1928, on the way to killing about 450 people."
March 12, 1928, 11:57:30 PM, 34N32'49" 118W30'45"
The St. Francis Dam was built between 1924 and 1926, in San Francisquito Canyon a little north of LA, to create a reservoir to control the Los Angeles water supply. At the above date and time, the dam "catastrophically failed," causing a flood hat killed at least 431 people. This one is for the record books, as the second deadliest disaster in California history after the 1906 San Francisco earthquake, and "one of the worst American civil engineering disasters of the 20th century." - I'm not sure whether to treat it as a flood or a structural failure, but perhaps I can use it twice!
The time given is for the moment the dam's power station experienced a sharp voltage drop, and an Edison transformer simultaneously exploded at a Saugus, CA power station, so the timing is quite easily confirmed. 12.4 billion gallons of water were dumped into the canyon in a wave that reached at least 120 feet in height.
The dam ruptured as Moon rose exactly, in partile conjunction with Antares and Sun was conjunct IC. I'd need an engineer to tell me what the particular tidal pattern of this was.
