On May 19 and 20, 1990, terribly significant rains fell within the river Basin, particularly over the lower finish of Lake Hamilton and far of Lake Catherine. within the twelve-hour amount from 6:00 p.m. May 19, 1990 to 6:00 a.m. May 20, 1990, there was downfall of 10 inches at Carpenter Dam, seven inches at Remmel Dam, and twelve inches in near Hot Springs, with most of the rain falling between 8:00 p.m. and 3:00 a.m. The pool elevation on Lake Hamilton was 399.16 feet higher than water level at 8:00 p.m. on May 19, however when four hours, had up to 402.12 feet, and was still rising. Throughout this point the gates on Carpenter Dam were opened so as to avoid flooding on Lake Hamilton. The mixture of the discharge from Lake Hamilton and therefore the influx of rain from Lake Catherine's catchment area flooded the shores of Lake Catherine. The tail water from Carpenter Dam rose from a traditional elevation of 305 feet, to an elevation of 331 feet by 4:00 a.m. on May 20. Before the flooding, the pool elevation at Remmel Dam was close to traditional at 304.33 feet, however the pool at Remmel Dam crested at 7:00 a.m. on May 20th at 4:00am at an elevation of 317.50 …show more content…
At the time Remmel Dam was in-built 1923-24 and once the project was swollen in 1947 AP&L consistently purchased and reserved easements on all the land adjacent to Lake Catherine allowing flooding to the degree it determined might be flooded in a very "worst case state of affairs," employing a study conducted throughout construction of Remmel and Carpenter Dams. The language of the easements varied, however all reserved or sent flowage and submersion rights either to a definite elevation variable per location on the lake, or covering the complete
The Grand Coulee Dam, located in Eastern Washington, was one of controversy, risk, and a point of no return. While the water captured made the desert area blossom in agriculture and it powered some large cities, it created a sense of accomplishment, that humans can control Mother Nature. While many people were very excited for this new construction – which gives power and resources - at the time, some thought it should not be allowed, they are not proud of containing the Columbia River. In this analysis, I am going to focus on the economic and social effects that the Grand Coulee Dam created in its build.
This case analysis summarizes the outcomes of the performance, problems, possible solutions and recommendations for Spring Princess based on the results in the Qutopian Market days on the 28th September and 12th October, 2013. Spring Princess made a profit of Q$3,370 by selling out 68 units in total with 1 stock on hand. Spring Princess was the niche player the two competitors which are Thrifty Threads and To Dye For by having a %30.92 of market share.
Patoka Lake has not always been the exciting, enjoyable weekend get-away as many have remembered it. In the early 1960s, two communities surrounding the lake - Jasper and Dubois - would have suffered tremendously from the reoccurring flooding. The U.S. Army Corps of Engineers as well as the state of Indiana worked together through the Flood Control Act to create the reservoir, thus inventing the wonderful recreational area that surrounds Patoka Lake.
The Three Gorges Dam is an unfinished project which will be the largest dam ever constructed on the planet Earth. It is situated in China on the third largest river in the world – the Yangtze. The dam has been debated over since the 1919 and is still a hot topic of debate because of its many pros and cons. In 1994 construction began on the dam, and it is expected to be finished by the year 2009. The massive dimensions of the dam are mind boggling and its functions – if the dam actually works – are truly remarkable; however, with such a large structure also comes difficulties, sacrifices, and cynics. The goal of this essay is to lend an understanding of the dam itself, the prospective benefits of
However, the dams were of faulty construction. Dam number one which caused the flooding was constructed of coarse mining refuse that Pittston had dumped into the Middle Fork of Buffalo Creek starting in 1968. This dam failed first on the heels of heavy rains. The water from Dam number three then took out dams number two and then number one. Dam number three had simply
Streams formed that had never been there before, and rivers in the surrounding area rose more than a foot per hour. Johnstown had water in its streets, which was nothing new to them, but this time it was different. There was an air of fear around them. Surrounding railroad tracks were washed out throughout the day as the storm progressed. Eventually, nothing could move east or west, and all trains were stopped. Overnight, people at the club upriver noticed that the lake rose two feet over night. The spillway definitely couldn’t handle more water. Debris accumulated around the “innovative” fish screens that were put in place to make fishing easy and leisurely for the wealthy. The damns engineer left at 11:30 in hops of getting a message to Johnstown. In addition, a crew gathered in an effort to free spillway and raise the top of the
The digitized version of this primary source gives a relaxed feel compared to the picture at the Harry Ransom Center. The observer is able to interact with the primary source and can zoom in and out when needed. The brine pipes are hazy in the physical photo, but the digital photo is significantly enhanced. The advantages of the museum version are that because it is the original document, the observer can visualize the picture the same way as a person from the 1930s. The reader eighty-five years ago interpreted it as “environmental imagination” (Sayers). By seeing the actual document you can observe the physical aspects of the primary source.
The Grand Coulee Dam(G.C.D) changed Kettle Falls forever. Kettle Falls was a peaceful river where Native Americans fished every year. It is said that around 3,000 fish were fished every year. Then in 1933, everything changed when the Grand Coulee Dam started construction and finished on June 1, 1942, that is almost a decade. I feel like it is good that we built the Grand Coulee Dam. The Dam has great effects that have benefitted Washington. Two of them are the jobs people got in the Great Depression and Irrigation we got.
Nearly 13,000 years ago, glaciers moved across the earth. In the Pacific Northwest they created many rivers, including the Columbia. The rock that the Grand Coulee Dam was built on was carved out by those glaciers creating a sturdy base of the dam. It is located in the rain-shadow of the Cascade Mountain Range in a shrub-steppe grassland, which results in very little rainfall and high temperatures. There have been many Native American tribes, including the Spokane, Sanpoli, Nespelem, Lakes, Colville and many others that have lived along the Columbia River and have relied on it for many of their day-to-day necessities (Columbia Basin Project 2015).
Based on the events that lead to the devastating floods in Queensland and the eventual case that was brought against the engineers of the dam, there have been views from both sides of the divide as to whether or not the actions taken by the engineers were actually ethical or otherwise. We have explored this avenue and have found that both sides of the divide have good reasons to justify their actions. Firstly, we shall explore the avenue that the engineers decisions were appropriate and ethical. It can be said that the engineers did employ act utilitarianism in their decisions and actions, hence causing these decisions to be ethically correct. Act utilitarianism is essentially doing the right thing, which would benefit the majority of
In 1923-1947 Arkansas Power and Light (AP&L) constructed several dams on two Arkansas lakes, Hamilton and Catherine. AP & L obtained “flood easements” on property adjoining the lakes. AP&L sold lake side property and kept the easement in force. These flood easements permitted AP&L to “clear of trees, brush, and other obstruction and to submerge by
A mass curve and double mass curve were created for the Red Deer basin at Drumheller in 1964. Precipitation data was collected from the city of Drumheller, which is approximately 0.6 km from the river measurement. On average the greatest amount of precipitation occurred in May, June, and July, but there was a large spike in precipitation in the month of September. The lowest amount of precipitation occurred in January, February and October. The double mass curve for this basin has a large gradual increase. Runoff for this basin is always greater than precipitation, but there is an area of large run off and storage during the end of the curve. This could be due to the large amount of precipitation that occurred in September, and storage
These effects are perfectly normal when working with a reservoir and as he points out are not permanent. “Sodden garbage strewn about, dead trees, sunken boats, the skeletons of long-forgotten, decomposing water-skiers;”(147) These are all attempts to bring the reservoir in a negative light but these do not come from the reservoir but from careless patrons and the inevitable accidents. If the number of people who visited Lake Powell visited the former Glen Canyon area, the garbage and deaths and other negative aspects would be at the same ratio because some humans are simply careless and draining a reservoir is not going to change that.
Like surrounding regions of west Michigan, Lake Michigan plays a role in the climate of Plaster Creek. Lake Michigan’s effect on temperatures results in slightly warmer winters and cooler summers. This can be displayed in the average winter temperature of Plaster Creek which was recorded to be twenty-two degrees fahrenheit and an average summer temperature of seventy-one degrees fahrenheit. The climate surrounding Plaster Creek receives a fair amount of precipitation, with average rainfall totaling approximately thirty-six inches and an average snowfall which is estimated to be about seventy-eight inches. The topography surrounding this twenty-six mile stream varies greatly. One element that unifies the topography of Plaster Creek is the presence of large rocks and boulders. This is a consistent element of Plaster Creek’s topography is a result of glacial movement in the area.
Information that was used to develop my conclusions were relative to the history of Clearwater River such as the average normal discharge of 40,000cfs, the fact that the river can accommodate 55,000cfs before flooding will occur, and that with every increase of 2600cfs the river rises one foot. For example, this information helped to determine that four of the thirteen noted Peak Flood Discharges listed on the worksheet were not at flood stage as the river is able to accommodate discharges less than 55,000cfs. However, nine of the thirteen Peak Flood Discharges listed on the worksheet were at flood stage or drastically above; with the maximum rise of 17.77 feet above and a discharge rate of 101,200cfs. The average discharge rate of the top three noted floods per information on the Stream Gauge Data of Peak Flow Discharges is 93,613cfs, which is resourceful later in determining the extrapolated 75-year flood.
