St. Francis Dam Disaster
San Francisquito Canyon

[Series Index][Next Image]

Contemporary photo postcard of the remains of Power Plant No. 2 and the work camp, shortly after the St. Francis Dam disaster.

Construction on the 600-foot-long, 185-foot-high St. Francis Dam started in August 1924. With a 12.5 billion-gallon capacity, the reservoir began to fill with water on March 1, 1926. It was completed two months later.

At 11:57:30 p.m. on March 12, 1928, the dam failed, sending a 180-foot-high wall of water crashing down San Francisquito Canyon. An estimated 470 people lay dead by the time the floodwaters reached the Pacific Ocean south of Ventura 5½ hours later.

It was the second-worst disaster in California history, after the great San Francisco earthquake and fire of 1906, in terms of lives lost — and America's worst civil engineering failure of the 20th Century.
