St. Francis Dam burst, drowning over 400 people. It destroyed a huge part of Rancho San Francisco as it came out of San Francisquito Canyon and ran 15 miles through Rancho San Francisco and out to the ocean. It made much of the ground on Rancho San Francisco unusable for crops because of the mud and silt that now covered much of the property. The county of Los Angeles agreed to a settlement of over $750,000 but didn’t pay it out for almost 2 years. The name of Rancho San Francisco was officially changed to NEWHALL RANCH.
