Objective: The Hoover Dam is significant to the civil engineering and society because it helped the United States during The Great Depression, it required new engineering techniques to be established to have it built, and at the time of its construction it was the tallest concrete dam in the United States. The memo will also describe some other basic information about the Hoover Dam and an inquiry into scientific, social, and symbolic significance of the Hoover Dam. Introduction: The Hoover Dam, at the time of its construction was the largest concrete dam in the world. The Hoover Dam was constructed under the Boulder Canyon Project, which was authorized in the year of 1928, one year prior to the start of The Great Depression. The Hoover Dams
The Hoover Dam had successfully tamed the wild Colorado River by spanning from the Nevada wall to the Arizona wall. “Surveyors investigated seventy sites along the entire river's course and settled on Nevada's Boulder and Black Canyons, both offering a potential reservoir of more than thirty million acre-feet (Construction). The Hoover Dam is as tall as a sixty story building and its base is as thick as two football fields long. This was the tallest dam built at its time when completed in 1935. The dam had to be big, because it needed to hold back the biggest,... ... middle of paper ... ...Hoover Dam were many years ahead of their time and without them, we wouldn’t have the knowledge that we do today.
The huge dam was to be built to provide water for irrigation, flood control, and hydroelectric power. After several unsuccessful attempts to pass the agreement, President Calvin Coolidge signed the bill approving Boulder Canyon Project. Next, details were starting to be made for the damn. At first, the Boulder Canyon Project was planned to be built in Boulder Canyon. Later, the damn site was moved downstream eight miles to Black Canyon.

John R. Hall explains that the Hoover dam was built ¡§to harness the awesome power of the Colorado River¡¨ (22). The Department of Reclamation had a huge task on their hands when supervising the construction of the Hoover Dam (Hall 22), previously known as Boulder Dam and changed to Hoover Dam for President Herbert Hoovers strong support of a Dam on the Colorado River (Wassner 97). First, before even breaking ground, there had to be away to easily access the dam site and house the six-thousand workers who will build the great dam. Boulder City was created to house the Government and contractor ... ... middle of paper ... ...¡§Dam One Of¡¨). With Hoover¡¦s seventeen generators and extremely large water supply, cities were able to grow very rapidly.
This 45 years period is known as the golden age of dam building, starting with the construction of the Hoover Dam beginning in 1931. By the 1970s the golden age of dam construction began to come to an end with increased concerns of the impacts of dams on their surroundings. To better understand this time period I will look at the construction of Hoover Dam during the 1930’s followed by an examination many of today’s arguments for and against dams [i]. The need for a dam on the Colorado River was known decades before construction actually began due to the numerous destructive floods of the Colorado River. A need for water and electricity was also discovered to help with the development of the West.
Introduction: Crater Lake was discovered in 1853 by a few miners from California. After being forgotten, rediscovered and renamed from “Deep Blue Lake” to “Lake Majesty”, Crater Lake finally captured its name by a newspaper editor Jim Sutton. Although Crater Lake was discovered in 1865, it was created over 7,000 years prior to its discovery. Crater Lake was not always Crater Lake either, but was once Mount Mazma, a stratovolcano, which once stood roughly 12,000 feet high. Crater Lake is constructed of different types of volcanic rock, has been a part of different eruptions and has had much activity since it was once Mount Mazma.
Soon bureaucrats came together to create the Colorado River Project, wanting to create a series of dams along the Colorado River to create hydroelectric power and serve to control floods and droughts. With Buchanan dam well under way with a total of six planned Marshall Ford was the only dam designed primarily for flood control and the only dam in which USBR oversaw construction. With money scarce there was debate over the final height dam and it reservoir capacity. This issue resolves itself with the flood of 1938. Once completed Marshall Ford Dam would flood 65 miles of the Colorado to form Lake Travis, creating the largest of the seven reservoirs known as the Highland Lakes.
The newly formed state of California, influenced mainly by the Gold Rush starting in 1848, sent the population sprawling upwards drastically. As more and more people established residency in the future area of what would be called San Francisco, area leaders were finally able to officially establish the City of San Francisco in 1856. The invention of the cable car in the late 1880s helped facilitate the traversing the city’s steep hills, which ended up allowing people to live farther from work and transportation to the heart of the city. San Francisco started out with a base population of approximately 30,000 people and increased to roughly 13 times that size by the time that the earthquake struck the city in 1906. The earthquake and fires greatly exposed the poorly constructed buildings of previous years.
