largest dam in alaska

In short, loss of habitat is synonymous with loss of the animal population supported by the inundated habitat. mi. Davies, Lawrence E. "Controversy rages over plans for big Alaska power project". In the planning stages, the Interior Department also would be responsible for examining the economic feasibility of the project and its effect upon natural resources. Surprisingly, it isn’t even on most lists of the largest dams, because of its height of only 251 feet. Related Links. The main scope … Their habitations are miserable and their livelihood a bare subsistence supplemented by relief. The reservoir is also used as chlorine contact tanks, where chlorine is added for purification and given time to react with any pathogens, before it is supplied to the city. [42] Because of the large size of the proposed reservoir and the need to allow some flow of the Yukon River downstream of the dam site for river navigation and fishing, engineers anticipated that filling the reservoir would take no fewer than 16 years to complete. However, a 3 miles (4.8 km) long road had been built by AEL&P to the upper powerhouse at the base of the Salmon Creek Dam, which has since been de-commissioned. "[58], Supporters of the project suggested that the cheap electricity provided by the dam would be a strong enticement for electricity-intensive industries, such as aluminum smelting, to move to Alaska. The needed money was included in a House appropriations bill, and studies continued. Rather than becoming focused singularly on solely preserving the natural beauty of a particular landscape, as had inspired the creation of the U.S. National Park Service in the United States during the first half of the twentieth century, naturalists and environmentalists began to consider the human cost of development as well. The largest dam failure in U.S. history - the 1976 Teton Dam breach - was also the largest structural failure of any type in U.S. history, exceeding even the September 11 collapse of the World Trade Center. [28] Dam proponents also suggested that the electricity might be transmitted to the rest of the United States, lowering utility prices in those states by increasing the amount of available power. Fish and Wildlife Service press release. Building the Three Gorges Dam displaced more people than the three largest Chinese dams before it combined. [9], Hydrologically, the portion of the river upstream of the proposed dam drains about 200,000 square miles (517,998 km2). Blair, William M. "Dam on the Yukon stymied by Udall". Fish and Wildlife Service (FWS) released its report on the project. For named natural lakes The Corps of Engineers anticipated spending $618.4 million (1970 dollars) on construction of the physical dam alone, another $492 million for power-generating equipment, and $1.39 billion in total. Based on the plans prepared for the concrete arch dam and the two power stations, construction was started in May 1912. [50] Don Young, Alaska's representative to the U.S. House of Representatives, was elected to the Alaska Legislature in 1964 from Fort Yukon on a platform of opposition to Rampart Dam. [1][2][3][4], The dam was built by the Alaska-Gastineau Mining Company to meet the electrical energy needs for mining operations. Alaska Dam Safety Program Forms Fact Sheet on Dam Safety in Alaska (PDF) Alaska Administrative Code: Official Dam Safety Regulations Association of State Dam Safety Officials Otter Lake Dam: 7.5 mi. Davies, Lawrence E. "Alaskans press for a hydroelectric dam on Yukon". However, it was only in 1913 that the concept was transformed on ground by the pioneer mining engineer Thane. Williston Lake in the Peace River Alaska Highway region of Northern British Columbia, is the largest lake in BC. The tail waters from this power station was conveyed through a 10,000 feet (3,000 m) long power channel to the second power station titled 'Powerhouse 1' located on the shore of the Gastineau Channel. [39] The power facilities would have consisted of twenty-two 266,000 kilowatt units and two 10,000 kilowatt service units. The resulting organization was called the Yukon Corporation for Power for America, later shortened to Yukon Power for America, Inc.[51] The organization began with a $100,000 budget, which it used to produce "The Rampart Story", a color brochure distributed in Alaska and Washington, D.C. to promote the dam project. [25], In April 1964, the U.S. (1,304 km) north to south M9.2 Good Friday Earthquake of 1964. [23] Following that objection, other groups began to organize during the 1963 North American Wildlife and Natural Resources Conference. Becharof Lake, the second* largest lake in Alaska, is located on the Alaskan Peninsula. [55] Among the group's members was Ted Stevens,[55] who was appointed in 1968 as one of Alaska's representatives to the U.S. [17], Concurrently, two power houses were planned to generate power for the mining industry from the reservoir's water – an upper power station with a 3 MW capacity about 1 mile (1.6 km) downstream of the dam and a lower power station with a 3 MW capacity near the shore of the Gastineau Channel. [1][2] Theoretically, the ideal constant angle arch in a "V"-shaped valley for such an arch dam has a central angle of 133° of curvature. [47], During the campaign that preceded the 1960 U.S. Presidential election, both candidates—Richard Nixon and John F. Kennedy—made campaign stops in Alaska. Alaska Dam Safety Program. The largest glacier outburst floods in Alaska are from the release of glacier dammed lakes. Chester Creek Dam: 1.1 mi. [23] The initial report included some figures about the size of the project. "Report on ASC's annual meeting". ANCHORAGE, Alaska (AP) - Planning will move ahead this summer on a proposed south-central Alaska dam that, if built, would be one of the largest dams This theory led to the development of the "constant-angle" (or variable radius) arch dam, which was also thinner in design. [67], In late 1960, the Alaska Conservation Society became the first large conservation group to oppose construction of the dam. [37] A period of about four years would have been required for preconstruction planning, including detailed construction surveying and finalizing the design of the dam, powerhouse, and other structures. [53] Gruening led a coalition of Alaska lawmakers that included most of the Alaska Legislature. [5][6] Both are operated and maintained by the Alaska Electric Light & Power (AEL&P). Further, according to the theory of constant-arch design, the arch action at the base of the dam exerts the maximum pressure on the base. [45], From the initial planning stages, proponents and opponents speculated that the large size of the reservoir created by the dam could affect the weather in Interior Alaska and the Yukon. The DRC report, though trumped by the Interior Department's new precedence in such matters, nevertheless released a report in April 1962, stating that the project was economically feasible and would attract new industries to Alaska. Humpback Creek Dam near Cordova, Alaska … ... this site on the Yukon River would easily be one of the major potential hydroelectric power developments in North America. When the Trans-Alaska Pipeline was proposed in the late 1960s and early 1970s, Native organizations that had formed to oppose Rampart Dam were revived in opposition to the pipeline. At that point, the river turns west and southwest, flowing through the Yukon Flats, a low-lying wetland area containing thousands of ponds, streams, and other small bodies of water. Becharof Lake, the second* largest lake in Alaska, is located on the Alaskan Peninsula. Gruening, Ernest. The project was designed and supervised by Binnie & Partners of London, and it was built by Mangla Dam Contractors, a consortium of 8 U.S. construction firms, sponsored by Guy F. Atkinson Company of South San Francisco. The following table lists the largest man-made dams by volume of fill/structure. Dam Safety Engineer AK Department of Natural Resources 550 W 7th Ave Ste 1020 Anchorage, AK 99501-3562 Email: [email protected] Tel: 907-269-8636 Fax: 907-269-8947 State Program Statistics February 19, 1965. Alaska has about 67 named artificial reservoirs, C[›] approximately 167 named dams, C[›] and about 3,197 officially named natural lakes, C[›] B[›] out of over 3,000,000 unnamed natural lakes. The average width of the stream is 30 feet (9.1 m) and depth of water is about 1.5 feet (0.46 m). Humpback Creek Dam near Cordova, Alaska Anchorage. 3. The Fort Peck Dam ranks 5th on our list of largest hydroelectric dams in USA. Among Alaska’s valuable energy assets is the Bradley Lake Hydroelectric Project. The reservoir submerged two cities, 114 towns and 1,680 villages along the … By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list. Rampart Dam and the Economic Development of Alaska (Ann Arbor: the University of Michigan School of Natural Resources, March 1966) at 49. On the south bank would have been a concrete gravity spillway with a crest at elevation 600 feet (183 m) and a maximum flow of 603,000 cubic feet per second (17,100 m3/s) at maximum pool elevation. Though one of the biggest dams in length, the Cochiti Dam is one of the shortest in height. Because of these objections, United States Secretary of the Interior Stewart Udall formally opposed construction of the dam in 1967, and the project was shelved. Brooks, Paul. Alaska Dams: A list of all the Dams in Alaska with maps, driving directions and a local area search function. The 1960 United States Census recorded just 226,127 people as residents of Alaska, making it the least-populated state in the United States at that time. Norris, Frank; Johnson, Julie; Anderson, Sande; and Hovis, Logan. The dam… A concrete quantity of 54,000 cubic yards (41,000 m3) was placed on the dam. [7][8][9], The creek runs for a length of 3 miles (4.8 km) within the watershed, which has a creek divide of 1.5 miles (2.4 km) and a ridge line of 2.2 miles (3.5 km). Country Gardens Nursery Dam: 6.4 mi. The tram-way was built for hauling material for constructing the dam and its associated power stations. Teton Dam was built despite strong concerns by USGS geologists, and its failure caused 11 deaths and an estimated $2 billion in damages. September 8, 1978. Deteriorated concrete was removed, the dam body was regrouted and the upstream face of the dam was provided with a layer of high strength concrete in the top 45 feet (14 m). On today's episode of Latitude, we look at the water agenda of neighboring country China along India's frontline after its announcement of building the world's largest dam.The hydropower capacity is said to be built three times more than the three gorges dam, which is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, … The Mangla Dam as one of the largest dam is located on the Jhelum River in the Mirpur District of Azad Kashmir, Pakistan. In this design, the central opening angle is constant whereas the arch radius increases from the base to the crest; this increase towards the crest is proportional to the increase of the canyon width of the gorge. [3] The dam was designed with a base width of 47.5 feet (14.5 m) (width of 37.5 feet (11.4 m) is also mentioned in one source) and it tapers to a width of 6.5 feet (2.0 m) (6 feet (1.8 m) is also mentioned in one source[7]) at the top over a dam height of 168 feet (51 m). [89] The final nail in the coffin came on December 1, 1978, when President Jimmy Carter authorized the creation of the Yukon Flats National Wildlife Monument,[71] which became the Yukon Flats National Wildlife Refuge in 1980. Tarbela Dam, which is located in Pakistan, is the largest earth filled dam in the world. Area = 665,384 sq. The Spurr report determined that the scenarios offered as justification for the project were overly optimistic with respect to Alaska's projected long-term population growth, its per capita use of electricity, and the predicted rate of entry of electroprocess industries like the aluminum industry (which had substantial power requirements) into Alaska. Several United States congressmen and fiscal conservatives protested the proposal on the grounds that the money that would be spent on its construction would be better used to support other projects. [37] The reservoir would have reached a pool elevation of 550 feet (168 m) in the 21st year, the dam would have been completed to elevation 660 feet (201 m) in the 25th year, and the reservoir would have been filled to the full 640-foot (195 m) level in the 31st year after the project's start. [67] Conservation groups opposed the dam's construction because it would flood the Yukon Flats, a large wetland area that provides breeding ground for millions of waterfowl and habitat for game and fur-bearing animals. Conservation groups abhorred the threatened flooding of the Yukon Flats, a large area of wetlands that provides a critical breeding ground for millions of waterfowl. [1][13][14], In arch dam design, two basic shapes are adopted. Stretching an incredible 290,000 acres, the lake measures 35 miles long and 15 miles wide and reaches depths of as … This occurs no later than early November and lasts until mid April. In the spring, however, the area around the lake would have been prone to increased precipitation due to the phenomenon of lake-effect snow. This man-made lake was created when the W.A.C. The Salmon Creek Dam is a concrete arch dam on the Salmon Creek, 3 miles (5 km) northwest of Juneau, Alaska. [41], At the projected pool elevation of 645 feet (197 m), the resulting reservoir would have had a total capacity of 1,145,000,000 acre feet (1,410 km3). "Memorandum of agreement", U.S. Army Corps of Engineers. Green Lake (Alaska) 1422323: 361 feet (110 m) Sitka: Grizzly Lake 1402999: 1,768 feet (539 m) Denali: Lake Guerin 1422351 [21] In the years that followed, the Alaska Legislature voted several times to allocate state funding for the project. Charles F. Cobb P.E. [16] Preliminary estimates said the project would cost $900 million (1959 dollars) and generate 4.7 million kilowatts of electricity. mi. [37] Housing and construction offices also would have been constructed for workers on the south bank of the site, and the cost for this effort was included in overall cost proposals for the project. Built in 1914, it is the world's first constant-angle arch variable radius dam. Surprisingly, it isn’t even on most lists of the largest dams, because of its height of only 251 feet. That plan was completed on June 25, 1971, and it included most of the previous federal documents pertaining to the project, including the electricity market studies published by the Department of the Interior in 1965, the Fish and Wildlife study of 1964, and other studies about the economic feasibility of the project. "Waterfowl—A Resource in Danger", 37th annual convention of the Ontario Federation of Anglers and Hunters. Although the average tree used for construction of a dam is 4 to 12 inches (10–30 cm) across the stump, use of trees up to 150 feet (45 m) tall and 5 feet (115 cm) across have been recorded. Bradley Lake which was constructed and is owned, by the Alaska Energy Authority (AEA), went into commercial operation in 1991 and is operated by the Homer Electric Association. Cooke, A. Both men gave their support to the Rampart Dam project, with Kennedy saying, "I see the greatest dam in the free world at Rampart Canyon, producing twice the power of the Tennessee Valley Authority to light homes and mills and cities and farms all over Alaska. Related terms: breakwater, dike, jetty. [26] In January 1965, the Bureau of Land Management set aside almost 9,000,000 acres (3,600,000 ha) of land for construction of the dam and reservoir. Fiscal conservatives opposed the dam on the grounds of its large cost and limited benefit to Americans outside Alaska. Tarbela Dam, which is located in Pakistan, is the largest earth filled dam in the world. However, it is one of the 10 largest earthen dams in the United States, and for good reason. When a dam bursts, there is a sudden release of massive volumes of water which flood areas around the dam causing extreme loss of lives and property. The local people called it Tilhini meaning "dog salmon" a native name used by Tingit Alaskan Indian; this name is also shown in some early topographic maps. The failure of the dam on the Ru River in China’s Zhumadian City was the deadliest dam failure ever. In the mid- to late 1990s, more farm fields near it became tiled and drained into it, doubling its size and displacing more than 300 homes and flooding more than 70,000 acres of farmland. [11], During the Roman period, the theory of building a curved dam (arch dam) was known as a means to withstand the water pressure and hold the masonry joints. Today, … U.S. Department of the Interior. In 1984 a new power plant was built adjoining the old powerhouse, with installation of 6.7 MW capacity. March 14, 1962. The dam was completed, over a 13 months period, on August 13, 1914. In 1916, the average load on the two power stations was 5,187 horsepower (3,868 kW). Consideration also was given to the extension of the Alaska Railroad from Fairbanks to the site. The completion of the White Pass and Yukon Route railway from Skagway, Alaska, to Whitehorse in 1900, and the establishment of Whitehorse, located at … A Guide to Whitehorse. Dam Safety Engineer AK Department of Natural Resources 550 W 7th Ave Ste 1020 Anchorage, AK 99501-3562 Email: [email protected] Tel: 907-269-8636 Fax: 907-269-8947 State … Staff Report. [15] However, AEL&P gives design credit to their then Chief Engineer Harry L. Wallenberg for the Salmon Creek Dam. Bennett Dam was built in 1968. Largest Rivers USA by Volume Rank River Mouth Average Daily State Discharge in cfs 1 Misissippi Louisiana 593,000 2 St. Lawrence Canada 348,000 3 Ohio Illinois/Kentucky 281,000 4 Columbia Oregon/Washington 265,000 5 Yukon Alaska 225,000 6 Missouri Missouri 76,200 7 Tennessee Kentucky 68,000 8 Mobile Alabama 67,200 9 Kuskokwin Alaska 67,000 The first pouring of concrete was scheduled for the project's eighth year, and work on the powerhouse would have begun in the 11th year. The aggregates were mixed in designed proportions with cement and with a small admixture of lime to manufacture concrete for placing on the dam. [37] The installation of power generators was planned to follow as needed, with the last unit scheduled for installation by the 45th year of the project. [94], This article is about the canceled Alaska dam project. (Alaska State Troopers) The Tarbela Dam … Dams … A beaver may work alone or with family members to build a dam, using piled logs and trees secured with mud, masses of plants, rocks, and sticks. [77] Even sporting magazine Sports Illustrated got into the act, asking if the cost of so many waterfowl would be worth building the dam. Largest Beaver Dam Seen From Space The dam in northern Canada spans 2,800 feet and has likely been under beavers' construction since the mid-1970s. On the south bank, the land rises sharply to a ridge 1,500 feet (457 m) high. Yesterday, Alaskan governor Bill Walker announced that, as part of $1.5 billion in extensive budget cuts, the Susitna-Watana Dam project would be cancelled. The dam would be a concrete structure 530 feet (162 m) high and about 4,700 feet (1,430 m) long. [22] Salmon Creek Reservoir is now open for bait fishing all the year round. [15] The Rivers and Harbors Act of 1960 passed by the U.S. Congress in that year included a $2 million appropriation to conduct a full four-year feasibility study of the project, including its economic feasibility and the impact it would have on fish and wildlife. 52nd national convention, June 9, 1965. [8] In 1917, fish propagation was established in Salmon Creek Reservoir by introducing 50,000 fry lings (small and young recently hatched fish) in the reservoir with assistance from Alaska Fish and Game Club, which maintained a hatchery at Juneau. This system was commissioned by the City Borough of Juneau (CBJ) in 2015. In 1960, Harold Moats of the Corps' Alaska district said, "Rampart Canyon, the big one, is Alaska's most valuable resource, and as it is developed, Alaska will take her rightful place in the family of states contributing richly to the economy of the nation and the welfare of the whole free world. [12], The "V" shape of the gorge at the dam site was adjudged ideal for building this type of dam at Salmon Creek site. At the elevation of 660 feet (201 m), the dam would have stretched for 4,700 feet (1,430 m) from north to south. After traveling the Yukon River, Brooks hypothesized that construction of the dam would be catastrophic from an ecological and human standpoint, would cost an exorbitant amount of money, and that the claims of attracting industry and tourism to Alaska were greatly exaggerated. The city of Sitka is struggling to pay off the Blue Lake Dam in a big way. When built, adoption of the constant arch design for the dam reduced costs by 20% because less concrete was needed to construct the dam. The geological condition at the base of the dam also dictated the type of dam as a flat rocky bed of 75 feet (23 m) width was available to lay the foundation for the arch dam without resorting to large-scale excavations. The first batch of concrete was placed on the dam on July 14, 1913. Be aware that data on volume of structure is not as easily available or reliable as data on dam … The project was planned for Rampart Canyon (also known as Rampart Gorge) just 31 miles (50 km) southwest of the village of Rampart, Alaska and about 105 miles (169 km) west-northwest of Fairbanks, Alaska. Senate. The project was planned for … The agreement stated the Corps would have responsibility for design and construction of the project, while the Interior Department would be responsible for running and maintaining the dam after completion. It was finally abandoned in 1998. Gruening Papers, University of Alaska Fairbanks. In the summer, the long periods of daylight would have caused the land around the lake to become warmer than the lake itself, also creating the possibility of storms. [89], The report was duly reconsidered, but in 1978, the Army Corps of Engineers confirmed the project no longer was justified. [82], Opposition to the dam project also arose in concern of the dam's cost. Three things we all need to survive, but finding them in the wilds of Alaska takes a bit more extra planning and work. However, this source is subject to seasonal high turbidity and also interruptions due to the annual maintenance of the generator units. km) 1,480 mi. Content is … [91], In summer 1985, the last remnants of the dam project were eliminated when the 8.96 million acres (36,300 km2) set aside for development of the dam were released by the Bureau of Land Management for other uses. km) 1,480 mi. [57] He also wrote that even if the dam was built and cheap electricity made available, "Alaska did not possess a competitive advantage". This man-made lake was created when the W.A.C. Weeden, Robert B. "The plot to drown Alaska". "Historical Development of Arch Dams. The expansion of the dam will provide approximately 27 % more electricity for Sitka … [43], The Rampart Dam's large size had a correspondingly large price tag. [42] Because the Yukon also is a transportation route, transshipment facilities were planned for below and above the dam site and would have been connected by road and rail links. Secretary Udall cited the fish and wildlife losses that would result, the availability of less-costly alternatives, and the fact that no recreational benefits would accrue. For the reservoir in Colorado, see, An artist's rendition of the proposed dam. Here is a look at some of history's worst dam failures: The 1975 Banqiao Reservoir Dam Failure. Dam Distance; 1. The Mangla Dam as one of the largest dam is located on the Jhelum River in the Mirpur District of Azad Kashmir, Pakistan. [26], A survey of the archeological and paleontological potential of the Yukon Flats, conducted in 1965, objected to the potential loss of the area. [81] It was feared that construction of the dam would block navigation routes and violate the treaty. [12] The dam envisaged storage of about 18,000 acre feet (22,000,000 m3) at the full reservoir level while it is 445 acre feet (549,000 m3) when the water is 25 feet (7.6 m) deep. This is a hydraulic earth-fill dam… A beaver may work alone or with family members to build a dam, using piled logs and trees secured with mud, masses of plants, rocks, and sticks. [18] The REAB hired David E. Lilienthal's Development and Resources Corporation in April to complete the study, and a team of Corps engineers and REAB members arrived in the state in June to study the Rampart project first-hand. The gorge is located 31 miles (50 km) downstream of the village of Rampart, 36 miles (58 km) upstream of the village of Tanana, and immediately downstream from the mouth of Texas Creek. Water barrier or embankment built across the course of a stream or into a body of water to control and (or) impound the flow of water. Basically, an arch dam is a structure that curves upstream and the water pressure is transferred either directly to the valley sides or indirectly through concrete abutments. Dam. Lake Oahe has a surface area of 685 square miles (1,774 square kilometers) and a maximum depth of 205 feet (62 meters). They pointed to the lack of existing infrastructure in the region and said it was unlikely that enough electricity generated by the dam could be sold at a high enough price to pay for its construction.
