St Francis Dam Disaster Presentation

September 15, 2021 Michael F Ballard Leave a comment

A car passed by the St. Francis Dam on the way to Powerhouse 1 on March 12, 1928. The driver saw a torch light at the base of the dam, and figured the dam keeper, Tony Harnischfeger was down at the base of the dam. A little while later, a motorcycle passed by the St. Francis dam just before midnight. The driver, Ace Hopewell, glanced over to the dam as he passed. All was calm. One can imagine how beautiful it was in the moonlight, giving off a white glow. He continued on his way to Powerhouse 1, where his shift began at midnight. A few minutes later, he heard a terrible crash. He stopped his motorcycle, smoked a cigarette and listened to the loud crashing sound. The area was known for landslides in the area….the Pelona Schist was unstable and often collapsed on to the road. He listened until the sound began to subside, and carefully, he continued on to work, looking for fallen rock. It wasn’t until he arrived at Powerhouse 1, that he was told that the St. Francis Dam had gone out. He was the last living person to see the dam intact.

Join the Historic Highway 99 Association of California on Tuesday, October 5 at 6:30 pm, for the story of the St. Francis Dam, the 2nd largest tragedy in California as far as loss of life. Presented by the St Francis Dam National Memorial Foundation.

A while back, I found a really interesting presentation on dams throughout California. Everything from records to failures is covered. I encourage all interested to check it out.

Side view of the dam. Note the lack of any real spillways in the dam. Water was about one foot below the rim of the dam the day of the collapse.

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.
