Controversies Over Glen Canyon Dam Glen Canyon Dam is located on the Colorado River near the city of Page in northern Arizona. Construction of the dam started in 1956. It was meant to function as a water storage and a delivery center for the Lover Colorado River Basin to get sufficient water in times of drought. Glen Canyon Bridge was built by U.S. Bureau of Reclamation to support the construction of the dam. In 1966, the dam was completed (“Glen Canyon Dam” n.d.). Its reservoir became to be known as Lake Powel, which is the second largest in the nation with 1,960 miles of winding shoreline and 186 mile-length, next to Lake Mead (“Upper Colorado Region” 2016). After the completion of the Glen Canyon Dam and the emergence of Lake Powell, numbers …show more content…
Dominy argues that U.S. Bureau of Reclamation has contributed to irrigation, hydropower, flood control, and recreation by building the Glen Canyon Dam (McPhee 1971). According to Reclamation, eight generators of the Glen Canyon Dam annually produces hydroelectric power amounting to about five billion kilowatt-hours, which is enough to support growing needs of the western U.S. states of Colorado, Arizona, Utah, Nevada, Wyoming, Nebraska, and New Mexico, with a total capacity of 1,320 megawatts (“Upper Colorado Region” 2016). About four million customers enjoy the benefits of the hydropower (Loomis 2013). It is said that revenues having generated by Glen Canyon Dam are amount to $1.5 billion (“Glen Canyon Dam” n.d.). Furthermore, revenues from its production have been used to establish environmental programs relating to Glen and Grand canyons (“Upper Colorado Region” 2016). In fact, funding for such projects is one of the purposes of its construction (DamNation …show more content…
Dominy mentions that U.S. Bureau of Reclamation makes Lake Powell accessible to people; about six hundred thousand people come to Lake Powell each year to enjoy fishing, hiking, swimming, water-skiing, and sun-bathing (McPhee 1971). It means that Lake Powell creates new jobs related to tourism and generates higher incomes and revenues into local communities. In fact, National Park Service report mentions that Glen Canyon National Recreation Area and Rainbow Bridge National Monument attracted about two million visitors in 2013, bringing over $118 million to local communities. This, in turn, supported 1473 jobs in those communities (National Park Service
There are three dams directly on the Genesee River, one at the south end of the park and two at the north end (Fish, n.d.). According to the Fish and Wildlife Service, the dam at the south end of the park is the Portageville Dam, which was built for irrigation and affects 45.16 miles of river. The Portageville Dam is not documented on the cu...
The Post Falls Dam has stoically served North Idaho for over 100 years and is arguably one of the greatest social and geographical influences in the region today. To appreciate the history of the dam, it is important to start at the beginning, before the dam was built, even before there was a Spokane River or a Lake Coeur d’Alene.
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.
Hoover, Glen Canyon, and the Three Gorges. What do these three things have in common? They are all man-made dams. Throughout the world, man-made dams affect the three pillars of sustainability. A legend of controversy surrounding these dams has created a unique background story, as well as shown the positives and negatives of these man-made wonders.
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.
Grand Coulee Dam is a hydroelectric gravity dam on the Columbia River in Washington State, built by industrialist Henry J. Kaiser It is among the most famous dams in the United States. The reservoir it created is called the Franklin Delano Roosevelt Lake. The reservoir is named after the United States President who seemed to love dams and hydroelectric power and who was involved with the project through to the final completion of the dam. The dam was built as part of the Columbia Basin Project as a way to irrigate the desert areas of the Northwest United States. The dam started during the 1930s as a public works project and finished toward the beginning of World War Two. The initial construction plan was reconfigured during construction for more height. Its height was determined by the point at which the water from the reservoir began backing up into Canada. The scope and size of the dam is hard to comprehend. It is over a mile long and taller than the Great Pyramid of Giza, in fact, all the pyramids at Giza can fit within the base of the Grand Coulee Dam. The dam is so large that a truck at the base looks like a toy, this creates some perspective into the dam's true size. When the dam was completed in the early 1940s it was the largest dam in the world.
Imagine a scenic, wild landscape with animals that roam freely, cascading waterfalls, and mountains that seem to scrape the pale blue sky. This is what one thinks when first hearing the name Yosemite National Park. Unfortunately, the reality is completely opposite. Yosemite is now under a federally regulated Class 1 area under the Clean Air Act, which is equivalent to the pollution of Los Angeles (“National Parks Service”). It is a sad comparison to the past John Muir, who first documented Yosemite Valley, to today’s reality. The condition of Yosemite National Park should be introduced to the American public in order to protect its historic beauty and significance, eliminate current pollution, and prevent future repercussions.

Over the years Glen Canyon Dam has been the spark for hundreds of debates, rallies, and protests. These debates have been going on for almost forty years now. The fact is that the dam created a huge lake when it was built, this is what bothers environmentalists. This lake is called Lake Powell and thousands of people depend on its tourists for income. The lake also filled up a canyon called Glen Canyon, some people say it was the most beautiful place on earth. The anti-dam side of the debate has its basis in the fact that Lake Powell is currently covering Glen Canyon. It was very remote so few people got to witness its splendor. This is probably the reason the dam was built in the first place, ignorance.
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.
Groundwater remained the main supply until 1971 which was when Las Vegas became more dependent on Colorado River water due to the “Southern Nevada Water System” (Brown, n.d.; Larsen et al., 2015). Since then up to 90,000 acre-feet of groundwater has been pumped on a yearly basis, this value surpasses the natural groundwater recharge (Laczniak et al., n.d.). Rain as well as snow serves as the primary sources of groundwater recharge for the aquifers while precipitation plays a minor role (Laczniak et al., n.d.). Due to there not being balanced discharge and recharge this has led to subsidence and as a result of this subsidence the storage capacity of aquifers has decreased due to compaction (Laczniak et al., n.d.). It is estimated that 187,000 acre feet of storage capacity in the aquifers has been lost due to compaction (Laczniak et
The Hoover Dam is a modern marvel and a testament to American ingenuity. At over six million six hundred thousand tons and jetting seven hundred sixty feet from the canyon floor, six hundred sixty feet across the bottom and, one thousand two hundred forty four feet across the top, the structure is awe inspiring even to a modern audience. Three quarters of a century since its completion it still stands as a symbol of one of the greatest construction projects of the ages. The need for a dam to block the Colorado River was not a new idea when construction began in 1931, but had been mulled around since the dawn of the century. Flooding due to runoff from the Rocky Mountains had devastated crops, and a need for hydroelectric power increased the need for a dam. In 1922 Black Valley was chosen as the spot for the dam’s construction. No one construction company was large enough to take on the project alone, so a group of companies formed a joint venture in order to bid the job. The Six Companies Inc. made up of Morrison-Knudson, the J.F. Shea Company of Portland, MacDonald & Kahn Ltd, Pacific Bridge Company of Portland, Henry J. Kaiser, Bechtel Company of San Francisco were awarded the winning bid for the dam at forty eight million eight hundred ninety thousand nine hundred fifty five dollars. The construction management team had a Herculean task in building this behemoth and faced many problems in its construction. A few of the major issues posed to the team were diverting the Colorado River, provisioning the men and material to get the job done, and the actual construction of the Hoover Dam. The heights involved with project led to many safety obstacles that had to be overcame.
People from all around the world travel to the U.S. only to experience the great American national parks. According to the NPS 2015 Annual Visitation Summary Report, a total of 480,307,933 people visited national parks in the United States during 2015 both for recreational and non-recreational purposes. Ecotourism, an economic model that combines tourism with commerce, contributes to the maintenance of national parks and allows isolated small towns surrounding national parks to thrive. According to Frye and Nuest, in addition to the views, “these wonders of the Earth provide ample opportunities for visitors to hike, bicycle, climb, swim, horseback ride, and paddle” (PAGE NUMBER). Such activities contribute to the visitors’ experience and have resulted in great customer satisfaction (Roemer and Vasek 46). All of these activities, along with other further services such as lodging and dining, create income for national parks and local businesses, as well, as more employment opportunities for the people, working for both local business and at the national parks. The NPS website claimed that they employed approximately 22,000 permanent, temporary, and seasonal professionals. However, when the idea of commerce comes into play with the preservation of natural and historic sites, the danger to lose
Americans today tend to believe that the Colorado River drought has been a recent occurrence, although drought relief strategies have been implemented since early 1997. To summarize, in the book The Colorado River Basin Drought Planning and Organizations, Colorado is named as the original state to acquire a drought relief plan. For instance, various assume water levels are diminutive in the Colorado and blame is due to the previous ten years of drought throughout the United States. Although it is true that water levels are at a record low, initial plans in the early 1920’s to introduce manufactured structures into the water basin is the original reason Colorado’s water system began to be compromised. It follows, then the supplementary natural
