St. Francis Dam was a 1924 project intended to provide water to the people of California. It was designed by William Mulholland. The project, however, turned out to be a disaster, killing 600 people. The dam collapsed due to poor engineering. From this incidence, we learn that we should entrust competent individuals with responsibilities to execute projects. We also learn that we should not assume any sign of imminent danger.IntroductionThe St. Francis Dam was a concrete gravity dam. Its shape was curved. It was erected to allow the storage and regulation of water. The dam was located along the San Francis Quito Canyon, 40 miles northwest of Los Angeles, California, and 10 miles north of Santa Clarita. The dam was constructed from 1924 to 1926 by the Bureau of Water Works and Supply, currently known as the Los Angeles Department of Water and Power. William Mulholland was the general manager and chief engineer for the entire project. On March 12, 1928, the dam gave way. It flooded and killed 600 people. The disaster is considered one of the tragic civil engineering disasters in America. This marks the end of William Mulholland's engineering career. This research will provide insight into the possible causes of the dam failure. Data Collection In this research, I used primary and secondary data as sources of information. To obtain primary data, I interviewed relatives of people who, at one time, resided somewhere near San Francisquito Canyon, close to the site. I wanted to know if they knew the story of the catastrophic collapse of the St. Francis Dam. I wrote down some of their theories and opinions in a notebook in order to collect data. I also visited the site on a tour... middle of paper... this should never be taken for granted. Just as cracks and leaks on the walls of St. Francis Dam were presumed to have led to a catastrophic collapse, slight signs can be a sign of great impending danger. In conclusion, St. Francis Dam was a water storage project that ended up being a disaster. It was designed by William Mulholland, who many say was a great man with remarkable eyesight and drive. Unfortunately, in my opinion, he went out on his own and didn't have enough confidence in his fellow engineers. I also think he took lightly the signs that the dam was not strong enough to hold the water pressure. This caused the dam walls to collapse, killing 600 people. From this incidence, we learn that we must carefully consider the opinions of others when executing projects. We also learn that we should not assume even the slightest sign of imminent danger..
