Dammed Dams
The basic principle of a dammed dam is to prevent water from being passed. People have been continuing and to build and perfect these structures, not knowing the full intensity of their side effects. If one takes a weighing scale and put the benefits of the damns on one side and the side effects on the other side, the side effects will out weight the benefits 10 times over. One of these dammed dams has been placed on the river Colorado, actually not one but 40 of these dreaded dams. We should actually change the term River to a huge plumbing system. The Colorado River is known as the most controlled and legislated river in the world. In order to satisfy the needs of humans we have created the one of the largest plumbing system in the world so that we can go to our fridge and have a glass of water. The water has been taken from the river and the fridge has bee powered by the hydroelectric generators, which have been installed on the dammed damns. The consequence of these damn has been devastating to the environment. I therefore urge the student government association to organize an environment exposition so we can educate the students of Embry Riddle.
These dammed dams have had devastating effects on the ecosystem, which depends on the constant flow of the river to survive. Fish such has salmon and other species have considerably declined due to the fact they cant reach their breeding grounds. There are four fishes which are listed on the endangered species list and for them to be listed on the list it took a law suite!! I mean why does it have to take law suite to acknowledge the critical habitat of these species?? If one decides to fish on this river one has to keep in mind that most of the water is destined for the fountains in Las Vegas and the swimming pools in California. So I urge the student association to organize a exposition so we may realize that the water the fishes are swimming in is already bought. Where does all this water go?
Water the most unique compound on earth, which is required to sustain life by all life forms, is been used to the extent that at our currant progress of water consumption we will have a water war in the next 2 centuries! So where does all this water go?
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.
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...
Most of the rivers are the one being used by large communities like drinking water supply and for the farmers in their produce. The State of Department put together a commission of knowledgeable people and carried out an investigation about the risk and consequences of this project. Some of the conclusion about the spills were, for example, that: “A million of gallons of tar soil war poured into the Kalamazoo River in Michigan… 40 miles of this river still are contaminated to this day”. Another example of spills affecting communities, is the one in 2013, caused by a twenty foot crack in a pipeline, causing a huge spill of oil, damaging the residential neighborhoods and the Lake Conway in Arkansas. This spills and oil “accidents” are affecting not only the lives of people but also the wildlife, the ecosystems and the quality of air and water
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 article, Hidden Waters by Joanne Zygmunt describes how water is used in almost everything in the world. The article begins by stating agriculture soaks up the majority of all water and is depleting the limited supply. Roughly “70 percent of global freshwater withdrawals are for irrigation” (Zygmunt 8). Zygmunt, sates there are many unknown uses of water. For example, A hamburger contains “2400 litres of embedded water” (10). It is also stated the are different types of embedded water, “blue” and “green”. “Blue” is the water used in daily life. “Green” is water that is found underground (Zygmunt 11). Unlike other natural resources, there is no substitute for water. The effects of water shortage depend on water utilization, environment
The Klamath Lake, along with other various rivers, lakes and canals that surround it, are the basis for almost 500 species of wildlife in southern Oregon and parts of northern California. It also serves as the most important factor in a farmer’s livelihood; their irrigation. The basis for the water crisis that is going to today in this region is that the current water levels and somewhat water quality are diminishing and reeking havoc on the area’s wildlife. The most notable argument from our guest lecturers and Steve Kandra (our somewhat uninvited tour guide), is that the water levels are too shallow for the two species of sucker fish to fully mature and to spawn. This makes it difficult to the many other species that rely on the sucker for a source of food, the most popular being the bald eagle, which is also an endangered species. Aside from the wildlife issues, the other main issue involved in this water crisis is the right to water usage. Some of these water rights date back many years but, they are still having difficulty deciding who gets to use the water and exactly how much they should use. There are also many other parties involved in this crisis, aside from environmentalists and irrigators, which I feel, are left out and many people don’t realize their role in the crisis.
Why is the government willing to disregard loss of endangered species, and losses of wildlife and further fish contamination when those environmental impacts are still happening from their first two dams on the Peace
Yet, there is no such thing as “clean hydro power,” with the exception of very small-scale hydropower dams at the individual or neighborhood level. Hydro powered dams can cause major fluctuations in downstream flows, and even dewater the stream channel, leading to direct death of fish and other species. The main effects of a dam on a river is that it disrupts flows, lowers water quality, blocks the movement of rivers vital nutrients and sediment, destroys fish and wildlife habitat, and eliminates recreational opportunities. Reservoirs slow and broaden rivers, making them warmer, reducing water quality, and harboring destructive nonnative species that scatter throughout the watershed and prey on and compete with native wildlife. The environmental, economic, and social impacts of a dam and reservoir may run the entire length of the river from the highest mountain peaks that feed the headwaters to the river’s outlet at the ocean according to
The Colorado River starts in the Rocky Mountains and cuts through 1500 miles of desert canyon lands of seven US states and two Mexican states to supply water the southwestern US [1, 2]. From early settlement, the basin states have debated and reassigned the water rights to the river; however, all the distribution patterns lead to excessive consumption of the resource [2]. In 1922, the seven states signed into the Colorado River Compact, which outlined the policy for the distribution rights to the water [3], however, this compact was written during an exceptionally wet period, which has shown to be uncharacteristic of the long-term conditions [4]. As the century progressed, the climate cycled into the traditional drier climate and by the 1950s, the river no longer met its delta in the Gulf of California [2]. Coupled with growing populations in the Western US in the late 20th century, the reservoirs and groundwater supplies have seen steady declines from a consumption pattern that is outpacing the system's ability to replenish itself and raises concerns about the future water supply [5].
Water resources tend to be taken for granted in New Jersey and why shouldn't they? Rainfall and runoff from snowfall are plentiful, averaging over forty inches per year. The state is bordered by the Atlantic Ocean on one side and the Delaware River on the other, with reservoirs containing billions of gallons of water, and large underground aquifers in between. It's hard to imagine a shortage of this abundant resource. Under normal conditions, this would be the case, but under drought conditions, as has been experienced throughout the winter of 2001 - 2002, the residents of New Jersey are forced to confront the stark reality of the situation that we may be entering into a severe water supply crisis. Mandatory water conservation and stiff penalties for noncompliance may do what preservation and antidevelopment advocates have been trying to do for decades in the state of Ne...
Our use of science and engineering sets us apart from all other organisms. We are constantly modifying the land, oceans and atmosphere. It is estimated that we have over 2,500 dams in Michigan. Of the 2,500 or so dams in Michigan, only about 114 are utilized for hydropower production. According to the Department of Natural Resources, “Most of the hydropower dams and related facilities are regulated by the Federal Energy Regulatory Commission (FERC), with the exception of a few small projects that do not provide energy to the regional power grid.” In other words, although it’s a different form of energy that is beneficial to the environment of Michigan, the amount of hydropower dams is not enough to make a significant impact. The DNR go on to say the following: “Hydropower dams only provide about 1.5% of the power produced in Michigan because Michigan's rivers are relatively small and flat in comparison to the larger projects in Eastern and Western States. Altogether, the hydropower dams produce only about 400 megawatts of power. The 10 largest hydro dams in Michigan, only 10% of all hydro dams, produce about 47% of the hydropower in the State. Hydropower production is a very small component of Michigan's energy production and is unlikely to grow
In the late 1800’s and early 1900’s, John Muir, a naturalist, and Marsden Manson, an engineer for the city of San Francisco, engaged in a heated debate over the construction of a dam in Hetchy Hetchy Valley. Muir wanted to preserve nature for the future, so he objected to the dam because he felt it would destroy the beauty of the area. On the other hand, Manson believed building a dam would provide water and electricity to the thousands of people who lived in the city of San Francisco, and this would preserve the well being of the human race for the future. Both men had good points and arguments to support their views; however, in the end you have to look out for your own kind. If there is a choice about the well being of the human race or nature, I believe there is only once choice to be made – the future support of the human race.
Houston, home to two major water reservoirs, now grapples with the task of safely releasing water from these dams. Because of Harvey, they are at a dangerously high level that poses many safety concerns. If the water continues to rise, the reservoirs could break, and release a tidal wave of water into the already flooded city. However, some residents don’t agree with the releasing of water, even in controlled portions, because it adds to the flooding. “The Addicks and Barker dams hold back the reservoirs’ collective 410,000 acre-feet of water and if the dams fail, half the city could be underwater” (Planas, Satlin, et al, 2). The release of water could be a major threat to nearby homes as well while causing more flooding on the major roads, perpetuating the issue of transportation. The Army Corps of Engineers ultimately decided that waiting and praying that the reservoirs didn’t fail would be a poor decision, and came out with a statement saying they would be releasing rationed portions of water. The overflowing of the reservoirs and the possible increase of flooding is a direct impact of Harvey on Houston, and this continues to perpetuate issues they will face in the months to
