St Francis Dam site in 2003.

This featured image covers two dates for a reason. The St. Francis Dam, a former dam in San Francisquito Canyon above Santa Clarita, California, collapsed at 11:57:30 pm on March 12, 1928. The ensuing flood caused a great deal of damage along the canyon and the Santa Clara River Valley. Over 500 lives were lost that night in, even in 2018, the second largest disaster by loss of life in California. The even had repercussions throughout the world. Following that event, dams, as well as other large projects, no longer were approved by engineers. Geologists had the final say, not engineers. Both geologists and engineers also had to be certified by their state government to work as professionals.

The head engineer on the project, William Mulholland, was a great engineer. He oversaw and helped design the Los Angeles Aqueduct, which was the largest and longest project of its time. It is still an engineering marvel today, more than 100 years later. The disaster ruined his career and during the investigation, he not only took full responsibility for the event, but also was said to have “envied the dead”. The collapse took a big toll on the “Chief” and he died a few years later.

This post is in memory of both those that died that fateful night in 1928 and to William Mulholland. A man that went from the “Savior of the City” to a pariah in just a few years.

March 12, 2015 will mark the 87th anniversary of the collapse of the St Francis Dam in San Francisquito Canyon, Los Angeles County, California. The collapse occurred just before midnight on March 12, 1928. It is still California’s second largest disaster in terms of lives lost. Approximately 500 people died in the ensuing flood which flowed to the ocean near Oxnard, CA along the Santa Clara River Valley. Only the 1906 San Francisco Earthquake and Fire exceeds the number.
