St. Francis Dam Tour 

Note: This event is sold out but you can join the waitlist at the online address below. The Santa Clarita Valley Historical Society hosts its annual tour of the St. Francis Dam site. Four historians will speak on the quest to bring water to the arid land of 1920s Los Angeles and how one man’s attempt to make it happen turned into the second worst disaster in California’s history. The failure of the St. Francis Dam at midnight, March 12, 1928, killed more than 400 people, leveled farms and homesteads, destroyed property and livestock and changed the way dam safety is addressed across the nation. The tour will begin in a lecture hall at COC and continue with a bus tour of San Francisquito Canyon, with stops at important points of interest. Tour leaders will narrate a moderate hike at each stop. Tickets for the event are $75 and may be purchased on Eventbrite, www.eventbrite.com/e/2025-annual-st-francis-dam-disaster-lecture-and-bus-tour-tickets-1128566124659.
