Los Angeles River
1938 was the same year that a terrible flood struck the region. From February 27 to March 1, 1938, a storm approached the California coast. Over 4.4 inches (11 cm) of rain fell. That was the equivalent of one-fourth the average yearly rainfall in the area. Finally, on 5:45 AM on March 4, the rain ended, and the flood slowly dropped in level. it seemed similar to the earlier flood in 1934. Everyone thought that it was already over, but it was not. 15 hours later, another storm hit Southern California, dumping another 6-10 inches (15–25 cm) of rain. The soils of the region could not take in any more water from the rains of the past few days. The three major rivers in the region, the Los Angeles, San Gabriel, and the Santa Ana, burst their levees and flooded three California counties.
