Fortuitously, at the time of the 1971 San Fernando earthquake the water height was 1,109 feet (338 m) (about half capacity: [3] 3.6 billion US gallons (14 × 10 ^ 6 m 3) of water) as a large landslide fell into the reservoir along with 30 feet (9.1 m) of the crest and upstream face reducing the freeboard to about 5 feet (1.5 m).
