Bureau of Reclamation Groundbreaking ceremonies took place on July 16, 1933, just days before funds were approved for another dam on the Columbia River--the huge Bonneville Dam, to be built downstream by the Corps of Engineers. [48], In 1963, when construction on the dam was well underway, the Sierra Club published a book on Glen Canyon, The Place No One Knew, featuring photographs by Eliot Porter, and lamenting the loss of the canyon before most of the American public had a chance to visit, or were even aware of its existence. The Sierra Club launched an extensive publicity campaign to sway public opinion against the plan; in response to the USBR's argument that new reservoirs would open up the Grand Canyon to recreational boaters as Lake Powell had, a full-page advertisement in the New York Times ran the slogan: "Should we also flood the Sistine Chapel so tourists can float nearer the ceiling? [75] [63], In 1956, work began on the two diversion tunnels that would carry the Colorado River around the dam site during construction. Wray revealed on Wednesday that the bureau has created a new unit to focus on threats against personnel after last year's search at Trump's Mar-a-Lago resort. 6 Title I of P.L. Exactly how much of this water has potential to return to the reservoir, and how much "disappears" into the ground, is subject to debate. Water managers and utilities state that the dam is a major source of renewable energy and provides a buffer for severe droughts. [53] Because of the isolated location, acquiring the land at the dam and reservoir sites was not particularly difficult, but there were a few disputes with ranchers and miners in the area (many of the Navajo Nation). [167][168] The base of the dam can also be reached via boat from Lee's Ferry. . [2] The outlet works consist of four 96-inch (240cm) diameter pipes, each controlled by a ring gate and hollow-jet valve. All exceptions must be approved on a case-by-case basis by Bureau of the Fiscal Service and requests may be sent to: pfc-reclamations@fiscal . I was within a few feet of his desk in Washington that day and witnessed how the forces long at work had their way. DARPA Defense Advanced Research Projects Agency. The crest of the dam is 1,560 feet (480m) long and 25 feet (7.6m) wide, while the maximum thickness of the base is 300 feet (91m). Glen Canyon Dam is a concrete arch-gravity dam in the southwestern United States, located on the Colorado River in northern Arizona, near the town of Page. [6] The units were installed between September 1964 and February 1966 at an original rating of 950 megawatts; an upgrade project between 1985 and 1997 brought it to its present capacity. Engineers decided to bury them in soil to act as a buffer against the potentially damaging vibrations. However, a more encompassing jobless level rose to . The Glen Canyon Dam remains a central issue for modern environmentalist movements. 8 short forms of Bureau Of Reclamation.Abbreviation for Bureau Of Reclamation: [70] Then, right before construction began, about 750 workers organized a strike because of a wage reduction due to the completion of public facilities at Page. [43], David Brower visited Glen Canyon shortly after the decision to build the dam, and "realized once he arrived that this was not a place for a reservoir". [67] Transporting workers and equipment to the bottom of the canyon was extremely difficult.

Summer 2011 saw the third largest June and the second largest July runoff since the closure of Glen Canyon Dam, and the water level peaked at nearly 3,661 feet (1,116m), 77percent of capacity, on July 30. Central Washington's Columbia Plateau was a prime candidatea desert with fertile loess soil and the Columbia River passing through.. However, their impact on the lake ecology appears to be low, or even beneficial due to their providing a food source for fish.[174]. Language links are at the top of the page across from the title. "[23], With the Glen Canyon site out of the question, the initial need for a reservoir was realized in 1936 with the completion of Hoover Dam in Black Canyon, storing 32million acre-feet (39km3) in the mammoth reservoir of Lake Mead. [5] The tunnels required 132,000 cubic yards (101,000m3) of excavation and another 110,000 cubic yards (84,000m3) of concrete lining. Even with the power plant and river outlet works running at full capacity, Lake Powell continued to rise to the point where the spillways had to be opened. [5], The two spillway tunnels are excavated through the canyon walls on each side of the dam.

The 1922 Colorado River Compact requires annual delivery of 7.5million acre-feet (9.3km3) to the Lower Basin states of Arizona, California and Nevada; the 1944 treaty with Mexico obligates the U.S. to allow at least 1.5million acre-feet (1.9km3) for use in the Mexican states of Baja California and Sonora. Initially, transport was done by barge from Wahweap Creek, but the fast current of the Colorado River could be dangerous. Today, it is the West's largest supplier of water and its largest producer of hydroelectric power, an agency truly "Managing Water in the West.". NZ New Zealand. Nonfarm payrolls increased 209,000 in June, below the consensus estimate for 240,000. US Bureau of Reclamation commissioner Camille Touton emphasized in June testimony to Congress that despite the agency's ongoing efforts to conserve water, much more needs to be done as climate. Prior to the completion of Glen Canyon Dam, about 4 to 6million acre-feet (4.9 to 7.4km3) reached the delta each year, despite heavy water use in California and Arizona. "[162] Despite its remote location, the 1,250,000-acre (510,000ha) Glen Canyon National Recreation Area, which surrounds the reservoir, receives more than three million visitors annually. [56] It was intended to serve a maximum population of eight thousand, accounting for the workers' families; the peak workforce would eventually exceed 2,500 in the busiest phases of construction. A dam in Glen Canyon was studied as early as 1924, but these plans were initially dropped in favor of the Hoover Dam (completed in 1936) which was located in the Black Canyon. The U.S. Reclamation Service, renamed the Bureau of Reclamation in 1923, was created to design and build these systems. In 1924, Reclamation reported that 143,000 people lived on the agency's 24 irrigation projects and that farm earnings for that year totaled $70 million. Nevertheless, Lake Powell rapidly approached the top of the spillway gates and construction efforts were subsequently focused on the left spillway in order to get it in operation in time. A plan called "Fill Mead First", which would drain Lake Powell in order to refill Lake Mead, has gained traction in recent years. Flood control has also caused an inability of the river to carry away the rockslides that are common along the canyons, leading to the creation of incrementally dangerous rapids that pose a hazard to fish and boaters alike. This was done due to the "equalization" guideline which stipulates that an approximately equal amount of water must be retained in both Lake Powell and Lake Mead, in order to preserve hydro-power generation capacity at both lakes. [137], The EIS completed March 21, 1995 cemented some restrictions on dam operations, limiting the maximum power release to 25,000 cubic feet per second (710m3/s), the maximum hourly "ramp-up" (increase in river flow) to 4,000 cubic feet per second (110m3/s), and the maximum "ramp-down" to 1,500 cubic feet per second (42m3/s). Glen Canyon Dam is the second highest concrete-arch dam in the United States, second only to Hoover Dam which stands at 726 feet. In winter 2005 (before the spring run-off) the lake reached its then-lowest level since filling, an elevation of 3,555.10 feet (1,083.59m)[132] above sea level, which was approximately 150 feet (46m) below full pool. The Census Bureau is transferred to the Department of Commerce. The spillway was closed down for inspections and workers discovered that the flow of water was causing cavitation the explosive collapse of vacuum pockets in water moving at high speed which was damaging the concrete lining and eroding the rock spillway tunnels from the upper ends of the diversion tunnels, which connect to the bottom of the reservoir. [82], It took more than 17 years for Lake Powell to finally reach its full elevation of 3,700 feet (1,100m) above sea level,[83] which it crossed on June 22, 1980. The repairs, in which air slots were installed to prevent cavitation shock waves, cost about $15 million. Known as the Freedmen's Bureau, this federal agency oversaw the difficult . In1993 Reclamation had 56 power plants on-line and generated 34.7 billion kilowatt hours of electricity. The site originally favored by the USBR was just 4 miles (6.4km) upstream, but the final decision was to build the dam 16.5 miles (26.6km) upstream because of stronger foundation rock and easier access to gravel deposits on Wahweap Creek. [14][20], The general consensus among inhabitants of the Colorado River basin and government officials was that a high dam had to be built on the Colorado to control floods and provide carry-over water storage for times of drought. [151] The river water temperature in 1983 was significantly higher than normal, due to a large portion of the water having come from overflows of warmer surface water over the spillways of Glen Canyon Dam, rather than the colder lower levels which feed the penstocks. [143] Because of the dam, sediment deposited by the Colorado and its tributaries is slowly filling up the canyon, and projections put the useful life of the reservoir at 300 to 700 years. [52] Because the dam site lay in a remote, rugged area of the Colorado Plateau more than 30 miles (48km) from the closest paved road, U.S. Route 89 a new road had to be constructed, branching off from US 89 north of Flagstaff, Arizona, and running through the dam site to its terminus at Kanab, Utah. [101][102], Glen Canyon Dam became the subject of influential literature, including Edward Abbey's novel The Monkey Wrench Gang (1975), which tells the story of a fictional group of environmentalists fighting against industrial developers in the American Southwest, their ultimate target being Glen Canyon Dam. Reclamation's name comes from its original goal, to "reclaim" arid lands for human use by providing a secure, year-round supply of water. Largest wholesale water supplier and second largest hydroelectric power producer in the U.S. 23 were here. However, with the potential damage that would be caused to the remote environment, "the cure would be far worse than the disease. It said that building Echo Park Dam and a "low" Glen Canyon Dam would save 165thousand acre-feet (0.204km3) of water per year over a "high" Glen Canyon Dam (which was ultimately the version to be built). If some Senator was causing him trouble, money for his project could disappear mighty fast. Background: The Bureau of Reclamation and the Era of Large Federal Water Projects The Bureau of Reclamation has been an important entity in shaping federal development efforts in the western states and territories. The minimum dam release was set at a meager 1,000 cubic feet per second (28m3/s) (increased to 3,000 cubic feet per second (85m3/s) during the summer whitewater rafting season), with a maximum of 31,500 cubic feet per second (890m3/s) during peak times; to respond to changing power demands, river flows could double or even triple in the space of an hour. At the time of construction in 1964, the steel penstocks feeding water to the power plant were exposed and they experienced severe vibration when in use. The defense says the government is out to discredit the organization", "Bureau of Reclamation Lake Powell Water Data for April 30, 2006", "Goldwater, Brower and the disastrous damming of the Colorado River: How two bitter opponents came to a meeting of the minds on water in the West", "If You Only Read One Book About the Water Crisis: 'Cadillac Desert', "The Colorado River system: Dams and drought", "Unplugging the Colorado River: Could the end be near for one of the West's biggest dams? However, in the following months it was discovered that the initial results were misleading. "[8], The proposal for Glen Canyon Dam was most vocally supported by the state of Arizona, which wished to get Colorado River water to Phoenix and Tucson, located hundreds of miles away from the Colorado in the center of the state. The bureau was established in 1902 by Interior Secretary Ethan Allen Hitchcock in the administration of President Theodore Roosevelt to provide irrigation water in order to "reclaim" unusably arid land for human benefit. [170][171] Trout are not native to the Colorado River system; they were stocked in the river below Glen Canyon Dam after the dam was built. When the gates of the dam were closed in 1963, the resulting reductions in river flow effectively dried up the Colorado River Delta, the large estuary formed by the Colorado River at the Gulf of California (Sea of Cortez) in Mexico. Other non-native fish such as smallmouth bass, striped bass, largemouth bass and black crappie were planted in Lake Powell to provide sport fishing opportunities. Floyd Dominy, Bureau of Reclamation Commissioner, 1966 speech[41], Floyd Dominy, commissioner of the Bureau of Reclamation, was a vital figure in pushing the project through Congress and convincing politicians to take a pro-dam stance, and to assuage rising public concerns. Between 1988 and 1994, Reclamation underwent major reorganization as construction on projects authorized in the 1960s and earlier drew to an end. The left tunnel was finished over three months later on May 19, 1959, slightly behind schedule.[69]. [86] According to USBR data for water year 2015 (a year when Lake Powell did not experience a significant overall gain or loss in volume), Lake Powell lost a total of 368,000 acre-feet (0.454km3) to evaporation and only 8,000 acre-feet (0.0099km3) to leakage. Since the year 2000, Lake Mead has steadily declined toward the critical level at which a shortage would be declared for the Lower Basin states. [92] On July 14, Lake Powell reached 3,708.34 feet (1,130.30m) elevation, a level that has not been exceeded since. [172], Like many U.S. lakes and reservoirs, Lake Powell has an active problem with zebra and quagga mussels, invasive bivalve species originating in eastern Europe. After the near disaster in 1983, the USBR has maintained a minimum of 2.4million acre-feet (3.0km3) of flood-storage space in Lake Powell at the beginning of each year, to guard against unanticipated high runoff. It was initially called the U.S. Reclamation Service but was renamed the Bureau of Reclamation in 1923. Congress passed the Reclamation Act, which created the United States Reclamation Service, in 1902 to "reclaim" the lands of the arid West and turn them into productive family farms. [121] However, the foundation rock at Glen Canyon consists of porous sandstone prone to spalling, in contrast to the stronger granite at the Hoover Dam site, forcing the Glen Canyon design to follow more conservative lines by greatly thickening the abutments, thus increasing the surface area through which the weight of dam and reservoir would be transmitted to the rock and relieving the pressure per square inch on the highly breakable cliffs. Echo Park was a pure indulgence in the most austere of deserts. The dependable natural flow past Lees Ferry is now believed to be about 13.5 to 14.6million acre-feet (16.7 to 18.0km3). Flood control releases are allowed to go higher, but must remain constant for the entire month. [91] Even this additional capacity was exhausted; discharges through the left spillway reached 32,000 cubic feet per second (910m3/s), and the right spillway was opened to 15,000 cubic feet per second (420m3/s). [55] Because of the hundreds of bays and sinuous side canyons, including those formed by the San Juan, Escalante and Dirty Devil Rivers, Lake Powell has an exceptionally long shoreline for a lake of its size about 1,960 miles (3,150km) at full pool, longer than the entire west coast of the continental United States. That's in part because of a difference in how the reservoirs fill, according to Mary Lee Knecht, the regional public affairs officer for the U.S. Bureau of Reclamation. In wet years, it captures extra runoff for future use. On April 1 of each year, the Bureau of Reclamation releases its official forecast of the AprilJuly (snowmelt season) runoff, and adjusts releases from Glen Canyon Dam accordingly to maintain Lake Powell at a safe level. In 1962 the workforce topped out at nearly 2,500 employees laboring on the dam. [73][136] The power plant has a total capacity of 1,320 megawatts from eight 165,000 kilowatt generators. The operation of Glen Canyon Dam helps ensure an equitable distribution of water between the states of the Upper Colorado River Basin (Colorado, Wyoming, and most of New Mexico and Utah) and the Lower Basin (California, Nevada and most of Arizona). It was believed to represent the annual flow as measured at Lee's Ferry, Arizona (the official dividing point of the upper and lower basins), 16 miles (26km) downstream of present-day Glen Canyon Dam. The contract for building the bridge was awarded to Peter Kiewit Sons and the Judson Pacific Murphy Co. for $4 million and construction began in late 1956, reaching completion on August 11, 1957. It looked as if they [Merritt-Chapman & Scott] were going to start losing money before they dropped a single man with a three-dollar shovel into that canyon. [93] Just as it seemed inevitable that the dam would fail, inflows fell and the dam was saved. [60] The engineer in charge of the project would be Lem F. Wylie, who had worked on Hoover Dam and had previously designed six other USBR dams. [150], According to biologist and river guide Michael P. Ghiglieri, many drowning deaths by boaters in the Grand Canyon have been caused or exacerbated by rapid hypothermia and hypothermic shock caused by entering the cold water. authorized the Bureau of Reclamation (Reclamation), among other federal agencies, to develop . [110] During the 20002004 Colorado River drought, when the basin experienced its lowest five-year runoff on record, Lake Mead would likely have gone dry and the Lower Basin experienced massive cuts, were it not for releases from Lake Powell. After a barge capsized, spilling tons of machinery into the river, a much safer cable-car system was installed. On June 5, 1976, Teton Dam in southeastern Idaho catastrophically failed. [90], Meanwhile, snow continued melting in the Rockies and Lake Powell continued to rise rapidly. [113][114], Much of the opposition to this plan is along political lines: Lake Powell is legally considered the Upper Basin's water, and Lake Mead belongs to the Lower Basin. On August 12, the left spillway gates were opened, releasing water at a rate of 50,000 cubic feet per second (1,400m3/s). [85] The actual loss was 13.4million acre-feet (16.5km3), twice the initial prediction, but river flow data indicates that further leakage after 1980 has been negligible. QLD Queensland. [16], In 1922, six U.S. states signed the Colorado River Compact to officially allocate the flow of the Colorado River and its tributaries. After the dam was completed in 1964, there were few restrictions on hydro-power generation. Colorado River levels returned to normal during water years 2014 and 2015 (pushing the lake to 3,606 feet (1,099m) by the end of water year 2015. Some organizations, such as Living Rivers, continue to believe that the dam has too large and severe of an effect on the river's ecology to make restoration efforts worthwhile. [75][76] By late 1962, concrete was being poured into the dam at a rate of 8,000 cubic yards (6,100m3) per day even as the workforce was scaled down to about 1,500. Reclamation data shows activities, including hydropower, water deliveries, payroll, and recreation, annually contributes more than $72.9 billion to the economy and supports 618,000 jobs. History: Reclamation Service established in the Department of the Interior, under the jurisdiction of the Geological Survey's Division of Hydrography, July 8, 1902, to administer the reclamation fund established by the Reclamation Act, also known as the Newlands Act (32 Stat. 3 Who was the first director of the Bureau of Reclamation? The 26.2 million acre-feet of water storage capacity in Lake Powell, created by Glen Canyon Dam, serves as a 'bank account' of water that is drawn on in times of drought. [141], Because of its tremendous ecological effect on the Colorado River, the Glen Canyon Dam has been subject to decades of criticism from the environmental movement. As more efficient methods of concrete pouring were installed, including conveyors and remotely controlled buckets, the workforce gradually decreased. Mussels are most commonly transferred from lake to lake attached to the hulls, and inside the bilge area of boats. [144][145] If no action is taken such as dredging or sediment sluicing, in a few hundred years, sediment deposits will begin to build up at the foot of the dam and will gradually block the different outlets, reducing the dam's capacity to store and release water.
