Santa Paula, CA — Three minutes before midnight on March 12, 1928, the St. Francis Dam collapsed, sending 12.4 billion gallons of water downstream. The resulting flood killed over 400 people, with 103 still missing to this day. The St. Francis Dam disaster is considered the second largest disaster in California history, in terms of loss of life, and is the largest man-made disaster in the state.

The dam was erected in rural San Francisquito Canyon; floodwaters traveled down San Francisquito Canyon to the Santa Clarita Valley, then turned west following the Santa Clara River south of Piru, Fillmore, and Santa Paula, through unincorporated Ventura County, out to the Pacific Ocean. It forever changed the communities in its 54-mile destructive path.

In remembrance of the 90th anniversary of the St. Francis Dam Disaster, the California Oil Museum will exhibit "When Dams Fail: Lessons Learned from St. Francis and Other Notable Incidents" from March 3, 2018 through July 8, 2018. This exhibit covers more than a century of time and provides a look into several of America's dreadful dam disasters, the impact on the lives of those affected, and the lessons learned through investigative research and retrospective evaluations.

Understanding the underlying causes for dam failures is a critical component to preventing recurrence and future incidents. Visitors will learn reasons dams fail, including design flaws, operational inefficiencies, and natural or environmental causes, as well as safety measures that have been implemented to reduce the risks to human life, property, and the environment from dam related hazards.

A special presentation will be given on Saturday, March 3, from 2 p.m. to 3 p.m. Archaeologist Anne Stansell will share her research findings on why the St. Francis Dam disaster has been largely forgotten on a state and national level, but tenuously remembered within the flood-zone. Seating for this special presentation is limited.
