In California, the St. Francis Dam fails; the resulting floods kill 431 people.
California
California is a state in the Western United States that lies on the Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With almost 40 million residents across an area of 163,696 square miles (423,970 km2), it is the largest state by population and third-largest by area.
St. Francis Dam
The St. Francis Dam, or the San Francisquito Dam, was a concrete gravity-arch dam located in San Francisquito Canyon in northern Los Angeles County, California, United States, that was built between 1924 and 1926. The dam failed catastrophically in 1928, killing at least 431 people in the subsequent flood, in what is considered to have been one of the worst American civil engineering disasters of the 20th century and the third-greatest loss of life in California history.
