William Mulholland’s story parallels the American Dream. He was into poverty in Belfast, Ireland and eventually would be the man that brought water to Los Angeles. Mulholland’s name would be synonymous with water in Southern California. However, his final creation would halt his hero status permanently.
Mulholland’s amazing rise from ditch digger to chief engineer for the Los Angeles Water Department was an amazing feat of hard work and dedication. He was a self-educated engineer and had a vast knowledge of civil policy and public administration. He proved himself worthy with technical assistance on other water-related projects in Arizona, Nevada, Central America.
Mulholland’s biggest task was bringing water to a quickly growing Los Angeles. He created the Los Angeles Aqueduct (still in use today) from the Owens River 200 miles north of the Los Angeles Basin. The project took 8 years to complete and was finished in 1913. The project did not fare smoothly as the farmers of the Owens Valley that depended on the river for irrigation were forced off of their lands as their farms and ranches quickly became a desert.
During the 8 years of construction on the aqueduct, the population of Los Angeles had doubled. The aqueduct simply was not enough and a reservoir was made a valid option for not only household water needs, but for the needs of the fertile San Fernando Valley’s ranches and farms.
Mulholland chose the San Francisquito Canyon for construction of a new dam. The canyon paralleled the aqueduct 30 miles north of Los Angeles city limits. The potential reservoir was also thought to be a backup plan for earthquake damage or sabotage (most likely from angry Owens Valley farmers) to the nearby aqueduct.

Also, the dam was never audited by any safety committees or public works offices. Too much trust was put into Mulholland himself. When Mulholland wanted to build higher, there was no one questioning his ideas. When there were leaks and cracks, no one else inspected them except Mulholland. Due to disasters like the St. Francis Dam, no one works alone anymore in high engineered projects from freeways to bridges.
Sadly, William Mulholland was responsible for the 2nd greatest loss of life in California history. His obsession with engineering accomplishments of epic proportion ended up being his demise.
While a large memorial stands for the victims of the St. Francis Dam in Ventura, a very appropriate and small memorial stands for William Mulholland in the Los Feliz area of Los Angeles: a fountain, a symbol of never-ending water for Los Angeles.
Behind Millerton Lake, lies an existing structure made up of concrete of 319 foot high, this dam is called the Friant Dam. In the San Joaquin Valley below the project's authority of Fresno, Madera, Kern, and Tulare; the water holds and deliver up to a million acres. In 1933 and throughout 1934, the state couldn't find enough contributors to buy revenues bonds to complete the project. Luckily, the River and Harbors Act of 1935 by the United States Congress came through and financed under the United State Army Corps of Engineers.
In December 1936 the United States Department of the Interior authorized the Lower Colorado River Authority to construct a low dam at the site of an old crossing on the river known as Marshall Ford. Marshall Ford Dam was completed in 1941 through the collaboration of the United States Bureau of Reclamation (USBR) and the Lower Colorado River Authority (LCRA) of Texas. The original purpose of the dam was to prevent floods from devastating Austin, TX. The capital city had substandard heavy damage from previous floods since its establishment in 1846. 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 one feature common to the Hoover Dam, The Mississippi river and the three gorges dam is that they all tried to control nature’s swings, specifically in the form of flooding. Before the Hoover dam was built, the Colorado river “used to flood spectacularly…but after 1900 the Colorado provoked a vehement response” (Pg 177). The response was simple, but large. The U.S. built several large dams, including the Hoover dam, on the Colorado to decrease its flooding and increase power and irrigation. Unfortunately, just as human control of the Colorado’s flooding increased, its organisms and habitats were detrimentally influenced, and the water became more and more salinated.
The primary goal of the dam, irrigation, was forgotten as the war time need for electricity increased. Aluminum smelting was vital to the war effort. Aluminum smelting requires substantial amounts of electricity and hydroelectric power plants are often built to provide electricity for these smelts. The electricity was also used to produce uranium for the Manhattan Project. After the war ended the original goal of irrigation resumed. Additional dams, siphons and canals were constructed that turned the coulee into a vast supply network that allowed the desert to bloom.
The Golden Gate bridge, standing as an icon of roadway innovations, took multiple engineers years to design and complete. They could not just simply build an ordinary bridge. They had to take into consideration the physics behind it, as well as, what kind of effect the environment would have upon the bridge. The bridge sits along one of the most active fault lines in the world, so engineers had to make sure their bridge could withstand a little movement. Today the Golden Gate bridge still stands tried and true, as does many other innovations that 20th century engineers came up with.
The world around us if full of many wonders, some world renown and appreciated, or some immaculate and taken for granted, such as the Mississippi River. In the passage from Rising Tide: The Great Mississippi Flood of 1927 and How it Changed America, author John M. Barry communicates his fascination with the Mississippi River by analyzing its complex mechanics and describing its enchanting nature. Through the primary application of two rhetorical strategies—logos and pathos—the author services his argument with intelligence and intuition while chartering his passion and zeal for the Mississippi River.
This statement ensures the reader that the dam was built “for the people” doing this without stating any facts that prove the statement. This statement also does not state why the U.S. government built Glen Canyon dam.
The use of turbines from dams to provide power was a brilliant idea until water levels started running lower than normal. The water waste from humanity is directly contributing to portions of it, aside from drought conditions affected by pollution, widespread fires battled, and more adds to the depletion thereof. When humanity is relying on power provided from dams to handle the demand, they are essentially relying on the assumption that water levels will always be there to provide it. The Hoover Dam provides power to the southwestern portion of the USA that has a large number of people.
Dams made from dirt are very weak and the South Fork dam was built entirely with dirt. From an engineering standpoint dams made with dirt needed to be built ...
...es the Yosemite Falls and the sequoia trees. One of the state’s problems is the appetite for water. The once fertile Owens valley is now dry and its waters tapped by Los Angeles. In the Imperial Valley, the eradication of water is controlled by the All-American Canal which gets its water from the Colorado River. In Central Valley the poor distribution is the water problem that is an imbalance lessened by the vast Central Valley project. California had cutbacks in federally funded water in the 1970sand 80s which led to California cities buying water from areas that had a surplus of water. But California failed to make a long-term to plan and the federal government stopped the funding of water to the state in 2003. But with all this being said and done, California remains to be a unique state with a lot of entertainment, history, agriculture and a productive economy.
California water war has been an great example of different cities fighting against each other since they all share the common characteristics of greed, and selfish. Back in the 1800’s, Los Angeles grew largely in populations when finally it outgr...

Americans have often used art to symbolize the relationship between themselves and their history. Therefore, art is used to honor and remember someone or an event where people died, through a memorial. As an example, The National World War II Memorial is a memorial to honor and remember the people who served in World War II. The success or failure of a memorial depends on how well it represents the image that people have of a certain person or event. Especially in America because they find the construction of a national monument so controversial that no memorial has been erected in the National Mall without a discussion. The National World War II Memorial on the National Mall was a poor addition; its location diminishes the formerly open space between the Washington Monument and the Lincoln Memorial, its design is vague, and it is a poor choice even when compared with the Vietnam Veterans Memorial. A very good start.
The state offered to sell the canal, the railroad company bought it for the right of ways yet had no need to maintain the dam, which due to neglect, broke for the first time in 1862. McCullough stresses that man was responsible for the dam and its weaknesses nearly thirty years before the great flood as he explains how the initial repair work was carried out by unqualified people and how the discharge pipes were blocked up.... ... middle of paper ... ... McCullough makes a firm argument for the responsibility of man, and asserts the blame on the necessary people, therefore I feel he makes a fair and accurate assertion which I would agree with.
It took 33 years to complete the canal. The effort resulted in a canal that serves as a vital commercial and military waterway. Many people had supported the need for this canal for war/defense purposes, travel, and trade. This route enabled ships to travel between Atlantic and Pacific ports without sailing around South America, saving distance of more than 7800 miles. Construction of this canal was not only a major engineering accomplishment, but it also was a political and economic victory for the United States (Winkelman 157).
