St. Francis Dam

This article from the Los Angeles Times is a grim reminder that big dams should be built by big government and this one was not; built by the city of Los Angeles and it failed due to bad engineering, as Wikipedia notes: “The dam failed as a result of defective foundations.” Retrieved November 16, 2018 from

Excerpt from the Los Angeles Times article.

There is a quiet campaign underway in northern L.A. County that deserves the support of people across California.

The Santa Clarita Valley Historical Society is pushing for the site of the St. Francis Dam to be declared a national memorial. The designation would commemorate both the dam and the more than 400 lives that were lost when it collapsed, the worst man-made disaster in California history.

The St. Francis Dam was squeezed into San Francisquito Canyon, about 20 miles north of what is now the city of Santa Clarita. Construction began in early 1925 and was completed in May 1926. Built to hold back some 12 billion gallons of water, the structure was more than 200 hundred feet tall and more than 1,200 feet wide.

About two years after it was finished, on March 12, 1928, just before midnight, the dam failed. Water had saturated a portion of the foundation underlying the dam, causing “uplift,” which expanded and destabilized its main concrete structure.

When the dam gave way, it let loose a 100-foot wall of water that raged for hours through the Santa Clara River Valley, blasting through Saugus, Piru, Bardsdale, Fillmore, Santa Paula, Ventura and other communities. The torrent morphed quickly into a flood not just of water but of concrete, asphalt, railroad rails and ties, farms, cars and homes. This gargantuan flow of debris was an equal-opportunity killer.

The first victims were city of Los Angeles employees. Lilian Curtis, who was several months pregnant, narrowly escaped after climbing a nearby hill while carrying her 3-year-old son. Her husband, Lyman, who worked for the Bureau of Power and Light, and two young daughters were all carried off.

A 12-year-old boy named Louis Rivera experienced something similar near Castaic Junction. Awakened by the rumble of the approaching water, he managed to grab his younger brother and sister and get them to higher ground. He watched helplessly as his mother and older brother got swept away.

There are dozens more stories like these. And there are no stories at all for the many victims who remain unidentified more than 90 years later.

The St. Francis Dam calamity has largely been forgotten, even though it is part of a larger saga that Los Angeles cannot help but remember.

The dam was built as a vital extension of the Los Angeles Aqueduct, the lifeline that continues to bring water more than 200 miles from the Owens Valley.

The project was the brainchild of William Mulholland, who at the 1913 opening of his “Big Ditch” said famously of the water that came cascading through its sluice gates: “There it is, take it.”

After the dam burst — an engineering failure for which Mulholland was largely responsible — he uttered a similarly terse statement during a coroner’s inquest: “The only ones I envy about this thing are the ones who are dead.”

In history and popular culture (most notably in the film “Chinatown”), the main victims of L.A.’s thirst for unbridled growth are the residents of the Owens Valley, the people whose water and land the city acquired by hook and by crook.
