The Colorado River, once a river full of silt and raw energy is now a river full of clear blue and harnessed power. There was only one thought that crossed my mind as I watched this film; was damming worth it. Was damming worth the violent deformation of some of the world’s most renowned natural formations. This quandary affected more than just the beautiful Colorado River.
The Columbia River, which runs through the Pacific Northwest and lower parts of Canada, is a stunning river. It once had, according to National Geographic, “as much as 43 million pounds (20 million kilograms) of salmon and steelhead a year.” from just one outflow; juxtaposed to today where there are roughly only “2 million pounds” taken from one fishing port in Oregon. That decrease was caused in part by Hydraulic Dams. These dams disrupt the salmon runs and destroy the migratory patterns. According to the movie Cadillac Desert the Columbia’s salmon run has decreased by 90%. This is an exponential environmental violation and an inexcusable lapse of judgment; all for the sake of power. Power, the life force of America; without power we are nothing.
Power is something that everyone uses weather we are aware of it or not. Power is something that is needed in order for us to perform the miracles of technology, to have light where there was none, to explore the depths of the ocean and the tops of the world. Power, it is the driving force of innovation and of life itself. As far as we, Americans are concerned it is a simple switch that we flip on. To the average American, power is just that thing that is always there. It is a constant in an era unknowing. The common American would never think of where their power comes from. A common American would never as...

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 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.
As dams became old and upkeep costs rose many were torn down. This allowed the river to flow freely again and the salmon population increased by 20%. It was discovered that the best way to increase the diminishing salmon population was to simply restore the rivers to their original state. In 2008, a judge ordered for the Columbia and Snake River dams to spill water, allowing the rivers to flow as they would naturally. This water flow allowed the salmon to swim along the currents, as they would have once done
This film was presented beautifully and was able to appropriately discuss all forms of water issues our world is having from shortages to contaminations to possible solutions. The filmed opened up with the city of Las Vegas, Nevada and how they have used up so much water that at the time the
This Paper will describe and analyze three articles pertaining to the ongoing debate for and against Glen Canyon Dam. Two of these articles were found in the 1999 edition of A Sense of Place, and the third was downloaded off a site on the Internet (http://www.glencanyon.net/club.htm). These articles wi...
Conflict between residents in northern Nevada and SNWA has risen (Brean, 2015). In 2012 the U.S. Bureau of Land Management announced its support of SNWA wanting to build a pipeline from rural Nevada to Las Vegas, rural Nevada being primarily in the northern portion of the state (Larsen et al., 2015). Residents including farmers who depend on water for their crops argue that redirecting water supplies would harm the environment and wildlife that inhabit northern Nevada (Brean, 2015). There is also an issue of oversubscription, this is due to the Colorado River not only supplying water to Nevada but neighboring states which include “Wyoming, Colorado, New Mexico and Utah” (Wockner, 2014). Both Arizona and California are expecting water shortages in the future as they too depend on the Colorado River (Wockner, 2014).
The fallout of the 1927 flood demonstrates the one of many continuing struggle in dominating the Mississippi River despite understanding the true nature of the river. For example, “The average gauge readings through the last three months of 1926… of the three largest rivers… was the highest ever known… no one at the Weather Bureau or the Mississippi River Commission correlated or even compiled this information” (pg 175). The failure in understand the nature of the river prelude to more elaborate control schemes by expanding the federal government’s responsibility in seizing full control of the Mississippi River from states jurisdiction. The U.S Army Corps of Engineers is fully responsible in constructing va...
Abbey attempts in his article to help the reader visualize Glen Canyon before it was dammed up. He uses a lot of pathos to help the reader “feel” the beauty of the previous Glen Canyon and the ugliness of the present. His article seems to be written not to the supporters of Lake Powell, but to those who side with Abbey, perhaps in an attempt to strengthen their resolve to do something about their beliefs. Abbey advocates the draining and naturalizing of the reservoir, allowing it to regress back to its natural state. Although the author is very talented at using connotations and figurative language, he focuses too much on pathos and a 20th century view of nature and lacks sufficient logos and ethos.
The building of the dam has created a problem with the sedimentary flow along the Colorado River, and important aspect for creating and livable habitat for fish, plants, and other wildlife. Since the building of the damn, we have seen four fish species go extinct, and a few more on the brink
The San Joaquin River Project was a plan completed in 2009 made to recreate San Joaquin River, which was dried up after dams were built in 1942. The San Joaquin River restoration is to bring back water flows from the San Joaquin river to the Friant Dam, and to revive the salmon and other fish population. There are two articles debating whether they either agree or disagree with the project. I chose the article, “River Plan Too Fishy For My Taste Buds”. This article came from The Fresno Bee newspaper, which correspondingly means it came from Fresno. The type of people who live in Fresno are farmers, workers who work for other people, democrats, and people who care more about jobs rather than the environment. I agree with this article from The Fresno Bee because I believe Bill McEwen, the author of this article, is the better expert because of his credentials and achievements. I will be using the article “River Restoration Project Offers a Sprinkling of Hope” by Daniel Weintraub to back up my argument.
Edward Abbey's heart lies in the once beautiful Glen Canyon. He describes all of his wonderful childhood stories of him floating down the river and how all it took was a paddleboat and little money. He tells of the great beauty of all the animals, insects, forestry, and ancient scenery the canyon once had. This is why Abbey feels reservoirs are doing terrible things for not only Glen Canyon but every river. When you think about it, a natural river untainted by the ways of machinery and humans is virtually non existent today. Any river large enough to have a dam and produce a substantial amount of electricity probably already has many of them doing so. Abbey feels they are ruining the environment and wildlife is being sacrificed. The risen waters of the reservoir drown all of the life that once lived. All of the beautiful scenery and historic sights are replaced by water marked rocks, muddy banks, and very small amounts of forestry and greenery. He believes the whole river is completely disrupted with every reservoir and dam. He highlights the fact that exploring the river now requires a tour guide boat or enough money to buy your own. Overall, Abbey does give some good reasons behind his opinion. However, I have a different belief on the matter. Although Edward Abbey uses strong personal experiences to persuade the reader to argue that the man made reservoirs are destroying the beautiful canyon and the environment, I think he overlooks the other possible opinions and the benefits of having them.
Next, hydro-electricity is electricity produced by moving water, flowing past a turbine connected to a generator (“Hydropower”). According to Nationalgeographic.c...

There are three parts to a typical hydropower plant. The first part is an electric plant where electricity is produced. The second is a dam that open and closes to control the flow of water. Water behind the dam goes into an intake and is pushed against blades in a turbine which causes them to turn. Then the turbine rotates a generator to create electricity.
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical energy.
