Hoover Dam
The Hoover Dam, built over sixty years ago, still stands today as one of the most outstanding achievements in civil engineering. “Construction on the Hoover Dam began September 30, 1930. The last concrete was poured in 1935 (Facts)”. The Hoover Dam, often called the “Boulder Dam” because the initial location was at Boulder Canyon about ten miles north up river from where it is located now at Black Canyon. The name “Boulder Dam” came from President Calvin Coolidge in 1928. Coolidge signed an act authorizing the boulder Canyon Project. It was named this because the study originally was at the Boulder Canyon on the Colorado River. July 3, 1930, President Herbert Hoover signed the first appropriation bill for the dam. During dedication ceremonies on September 17, 1930, Secretary Ray L. Wilbur announced that the name of the enormous structure was to be Hoover Dam. However, while Franklin Roosevelt elected for President soon after, continued to use the name Boulder Dam. It wasn’t until 1947 that a resolution of Congress made Hoover Dam the official name. The Hoover Dam is located on the Colorado River at the southern tip of Nevada and the Arizona border. 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,...

...Hoover Dam were many years ahead of their time and without them, we wouldn’t have the knowledge that we do today. The Colorado River is known for the scars it has left, but the Hoover Dam has finally tamed the wild Colorado and still will for many years to come.

John Adams Dam was built on another Genesee River tributary to form a recreational pond affecting 43.78 miles of river (Fish, n.d.). There is a small, unnamed barrier affecting 3.16 miles of Genesee River tributary in the center of the park. I assume that it had been used during the building of walkways or roads in the park; however, there is no documentation on the dam’s purpose.
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 negative aspects of Glen Canyon Dam greatly exceed the positive aspects. The dam’s hydroelectric power supply is only three percent of the total power used by the six states that are served by the facility. There is a surplus of power on the Colorado Plateau and with more and more power-plants being created in the western hemisphere, Glen Canyon Dam’s power is not needed (Living Rivers: What about the hydroelectric loss). Although the ‘lake’ contains twenty seven million acre feet of water, one and a half million acre feet of water are lost yearly due to evaporation and seepage into the sandstone banks surrounding the ‘lake’ (Living Rivers: What about the water supply?). The loss of that much “water represents millions, even billions of dollars” (Farmer 183). If the government were to employ more water efficient irrigation practices, as much as five million acre feet of water per year could be saved.

The Hoover Dam turbines provide a great amount of electricity to those living in the states of California, Arizona, and Nevada. The water level of Lake Mead currently affects the dam’s ability to provide power from the large sized turbines. When the water level of Lake Mead goes down from conditions affecting it, the dam’s ability to provide power directly affects the power companies supplying consumers. Fortunately, the water levels gained back some of that full amount while still shy of where it once existed. As stated, “But the increased elevation isn’t enough to reopen any of the four boat launch ramps closed in the past decade, Holland said” (Shine, C., 2011, para. 9). This definitely indicates that there is currently promise to recovering with close to the original levels even though it may not be excessively soon.

In The Artificial River, Carol Sheriff describes how when the digging of the Erie Canal began on July 4, 1817, no one would have been able to predict that the canal would even be considered a paradox of progress. One of the major contradictions of progress was whether or not triumphing art over nature was even considered progress. People were not sure during the nineteenth century if changing the environment for industrialization was necessarily a good thing. Another contradiction to progress that resulted from the Erie Canal was when people started holding the state government responsible for all their financial misfortunes. An additional contradiction to progress that the Erie Canal displayed was how many of its workers were either children, or men that lived lives that were intemperate and disrespectful to women. As American history students look back at the Erie Canal today, they generally only imagine how the canal was extraordinary for the residents of New York, but not all the issues and problems it also produced.
The thirties was a time of anxiety -- after the major stock market crash of 1929, the Great Depression was sparked. The economy is in the dumps, crime rate increased, mass migrations occurred, and much more. This despair inducing time caused a majority of the American people to be poor, or if they were rich before the incident, they would at least have a much less amount of money than they had before. Many people were looking for jobs, but the country did not have any jobs to offer them. Then soon enough, the president at the time, Herbert Hoover, issued the creation of the Hoover Dam, which had opened up a large amount of jobs for the people. Sure, the job was extremely dangerous -- hundreds died in the creation of the large dam -- but the people needed money. They would’ve done almost anything in the economic grave that they dug themselves in at this point. They originally hired mostly Chinese immigrants to build the dam, but soon enough, more people in need of money were up for the job. They also started using concrete for the Hoover Dam, which has stuck until today’s time, in which most buildings are made up of concrete. Concrete is so relied on today due to its toughness and durability. The Hoover Dam popularized the use of concrete in building.
