Marc Reisner's Coming Undammed
A dam is a barrier constructed across a waterway to control the flow or raise the level of water. (Dictionary 1) They are put in place with much care and patience. A dam is very carefully planned out. Where they are going to be placed? What type of soil it is going to be constructed in? When the plans are drawn out, every detail is gone over with a fine tooth comb. Marc Reisner has written an essay titled Coming Undammed, is an essay about him talking how he supports dam removals across the country. He has made some ideas about why he sustains his opinion, some of which I agree with, but mainly I oppose.
He starts off by talking about a dam that he had visited on the Elwha River, which has two dams within it. In the upper part of the river, the Glines Canyon dam, and in the lower dam just called the Elwha. His first point against the building of dams is how the silt in the ground surrounding this dam has begun to leak into the dam. Which he says will lead to big slurrying of the water and will eventually “add millions of dollars to the cost of decommissioning.” (Reisner 382) This may be the case, but is only the case in this instance that he has come across. The ground of all other dams is not made up of the same material as every other dam in the nation. The dirt in New York doesn’t have the same makeup as the dirt of the Hoover dam in Nevada.
The next idea that he had for opposing dams are the expunging of fisheries where the dams are. He gave the example of how “before the dams went in, the Elwha River churned out salmon as the Chesapeake Bay did crabs.” (Reisner 382) He also goes on to say that the fish were large and there were several types of fish with in the river. He concludes this point by saying that when the dams were built up, it shut off the fish habitation within the river and reducing the fish numbers. I agree that with him that the number of fish would be decreased with a dam being built. I think that the amount wouldn’t be that high to cause a major problem.

The primary purpose of Friend dam is to help regulate the flow of San Joaquin into available uses of its environmental, wildlife, and farmer’s impacts. The dam controls the flow of water delivery where it needs authorization first before the schedule can release any delivery waters into canals, steam, and wild life habitats. There will be agreements and many protocols to do with it first to avoid unnecessary spilling. There are 5 release schedules which include quantity of water available, time water, flood control requirements, release schedules from storage reservoir above Millerton Lake, and water user requirements. These benefits of flood control, storage management, modification into Madera and Friant-Kern Canals, to stop salty water from abolishing thousands of lands in Sacramento and throughout San Joaquin Delta, as well as deliver masses of water into agricultural lands in 5other counties in the San Joaquin Valley.
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 South Fork Dam collapsed and unleashed 20 million tons of water from its reservoir. A wall of water, reaching up to 70 feet high, swept 14 miles down the Little Conemaugh River Valley, carrying away steel mills, houses, livestock and people. At 4:07 p.m., the floodwaters rushed into the industrial city of Johnstown, crushing houses and downtown businesses in a whirlpool that lasted 10 minutes. (New York Times, 1889).
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
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.
In Glen Canyon Dammed: Inventing Lake Powell and the Canyon Country, Jared Farmer agrees with the draining of Lake Powell. Farmer goes on to write, “Consider the river that flows through Grand Canyon: it’s not the real thing. It’s the programmed discharge from Glen Canyon Dam”. (Farmer pg. XIII) In this statement Farmer is saying that he does agree with the dam coming down, although saying that people have their own opinions.
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 ...
The Colorado River is formed by small streams created by a huge amount of snowmelt from the Rocky Mountains. The ecology and flow of the river varies highly by region. The river is divided into two different regions, the Upper Basin and the Lower Basin. Beginning in the early 1900s, western states began to build dams in the Colorado river, diverting the water flow to fast growing cities like Los Angeles, San Diego, and Phoenix. The river now services over 30 million in the southwestern parts of the United States and Mexico (Patrick 1). Diverting the water of the nation’s seventh-longest river may be seen has a great accomplishment, however to others this is a great crime against nature. Over the past couple years the river has been running significantly low, since a drought has come up the southwest. At the lakes edge, “bathtub rings”, lines in the rock walls, can be seen showing the decrease in water level. It is recorded in some areas of the river that the water has lowered 130 feet since 2000. Some water resource officials say those areas will never be filled back to normal. The surrounding states must adjust to living with less water or further actions need to be taken to save the river’s water. There has been some talk about adding water to the river to replenish the river but nothing has hap...
Beyond all of Abbey's personal feelings and emotional memories, let us not forget about what these dams and reservoirs are providing us with-power. Electricity is extremely important to everyone. It is the reason for seemingly everything people consider vital to their lives; cars, computers, TV, running water through the faucet, everything. It is not something we can just forget about because of an author's emotional attachment to a certain strip of land sacrificed to make thousands of other people happy sitting safe in their home with electricity.
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.
Child labor refers to work that is mentally, physically, socially or morally dangerous and harmful to children; interferes with their schooling by depriving them of the opportunity to attend school; obliging them to leave school prematurely or by requiring them to attempt to combine school attendance with excessively long and heavy work (International Labor Organization). Child labor has been a big problem ever since the Victorian Era. Many counties worldwide have used and still to this day use child labor. Though there are many laws that have been implemented against using children to work, many countries tend to ignore them. In my paper I will be discussing countries where child labor is present, push to stop child labor, companies that use child labor, the effects on children, and the reasons for child labor.
Imagine you and I with such limited opportunities. Imagine if children like us did not know the joys of school life but rather the life of hard physical labor. Imagine if we had to struggle miles for water, work several hours a day to earn a few scraps of food that kept us barely alive. Unimaginable, yet the life of 215 million kids around the world today – child laborers. Children are engaged in the worst forms of child labor, many of them in agriculture. They use potentially dangerous machinery and tools, carry heavy loads, work long hours in extreme heat a...
The term ‘child labor’ is used to define any work that is mentally, physically and morally harmful to children, and interferes with their education (ILO). Children have been used as a labor force throughout most of our history. After decades of struggle aimed to combat the massive employment of child labor, the Convention on the Rights of the Child in 1989 ratified that children have the right to develop harmoniously their personality in a loving family environment. Moreover, it recognized the right of the children to be protected from exploitation, and any form of labor that jeopardizes their physical, mental and moral well-being. However, child labor is still eagerly diffuse in developing countries,
Child Labor had begun around the era of the Industrial Revolution. As the world was becoming more dependent on the workings of machines and all of the advancements the revolution was bringing along, more workers had to be employed in these massive factories in order to keep them running, and to handle smaller day-to-day tasks. Children around the ages of four or five would be found working in these factories, the conditions in these factories were incredibly dangerous, and much of the time, fatal. Looking at child labor in this way, many countries have deemed it a...
