For many Californians, the idea of a massive flood is unfathomable. However, those have been here long enough have seen these unprecedented 100 year storms.
During the span of 1964-1964, several spent typhoons hit the West Coast at San Francisco. It was deemed to be a “Truly Extraordinary Rainfall Event”. The Eel River went from 1500 cfs to over 700,000 cfs which is 1.5 times the average flow of the Mississippi River.
Preceding this event was a massive storm that turned Sacramento into a floating city. It was caused by an atomspheric river which is a band of water vapor that extends for thousands of miles about a mile up above the ocean. It took place from 1861-1862 and 66 inches of rain fell on Los Angeles and the Santa Ana River flooded in Anaheim. It was four feet deep in some areas and lasted over four days. The city of Sacramento was completely underwater.
