Meanwhile, the U. The first difficult step of construction involved blasting the canyon walls to create four diversion tunnels for the water.
Facing strict time deadlines, workers toiled in degree tunnels choked with carbon monoxide and dust, conditions that prompted a six-day strike in August The second step of involved the clearing of the walls that would contain the dam.
Suspended from heights of up to feet above the canyon floor, high scalers wielded pound jackhammers and metal poles to knock loose material, a treacherous task that resulted in casualties from falling workers, equipment and rocks.
Meanwhile, the dried riverbed allowed for construction to begin on the powerplant, four intake towers and the dam itself. Cement was mixed onsite and hoisted across the canyon on one of five ton cableways, a fresh bucket capable of reaching the crews below every 78 seconds.
Offsetting the heat generated by cooling concrete, nearly miles of pipe loops were embedded to circulate water through the poured blocks, with workers continually spraying the concrete to keep it moist.
As the dam rose, block by block, from the canyon floor, the visual renderings of architect Gordon Kaufmann took form. HOOVER DAM.
Im Stauraum sedimentieren die Feinstpartikel des aufgestauten Flusses auf dem Seegrund des Stausees ab. Dadurch werden heimische Fische des Colorado-River verdrängt; manche sind vom Aussterben bedroht z.
Ptychocheilus lucius. Eine weitere ökologische Auswirkung der Talsperre ist das homogene Abflussregime.
Da natürlich vorkommende Hochwässer durch die Talsperre abgepuffert werden, fehlen bereinigende Vorgänge im Flussbett.
Die fehlende Umlagerung von Gesteinen und die damit unterbundene Dynamik dieses Systems beeinflusst die Flora und Fauna nachhaltig. Zur Linderung dieses Problems wird alle paar Jahre bei ausreichender Wasserkapazität ein künstliches Hochwasser erzeugt.
Der Hoover Dam wurde von der American Society of Civil Engineers in die List of Historic Civil Engineering Landmarks aufgenommen.
Im August erhielt er den Status eines National Historic Landmarks. Today, Hoover Dam is used as a means of flood control on the lower Colorado River.
Storage and delivery of the river's waters from Lake Mead is also an integral part of the dam's usage in that it provides reliable water for irrigation in both the U.
In addition, the Hoover Dam provides low-cost hydroelectric power for Nevada, Arizona, and California.
The dam generates more than four billion kilowatt-hours of electricity per year and it is one of the largest hydropower facilities in the U.
Revenue generated from power sold at Hoover Dam also pays for all of its operating and maintenance costs.
Hoover Dam is also a major tourist destination as it is located only 30 miles 48 km from Las Vegas and is along U. Highway The high scalers received considerable media attention, with one worker dubbed the "Human Pendulum" for swinging co-workers and, at other times, cases of dynamite across the canyon.
When workers wearing such headgear were struck hard enough to inflict broken jaws, they sustained no skull damage.
Six Companies ordered thousands of what initially were called "hard boiled hats" later " hard hats " and strongly encouraged their use.
The cleared, underlying rock foundation of the dam site was reinforced with grout , forming a grout curtain.
This was done to stabilize the rock, to prevent water from seeping past the dam through the canyon rock, and to limit "uplift"—upward pressure from water seeping under the dam.
The workers were under severe time constraints due to the beginning of the concrete pour, and when they encountered hot springs or cavities too large to readily fill, they moved on without resolving the problem.
A total of 58 of the holes were incompletely filled. It found that the work had been incompletely done, and was based on less than a full understanding of the canyon's geology.
New holes were drilled from inspection galleries inside the dam into the surrounding bedrock. Bureau of Reclamation engineers calculated that if the dam were to be built in a single continuous pour, the concrete would take years to cool, and the resulting stresses would cause the dam to crack and crumble.
When an individual block had cured and had stopped contracting, the pipes were filled with grout. Grout was also used to fill the hairline spaces between columns, which were grooved to increase the strength of the joints.
The concrete was delivered in huge steel buckets 7 feet high 2. The buckets were then suspended from aerial cableways which were used to deliver the bucket to a specific column.
A total of 3,, cubic yards 2,, cubic metres of concrete was used in the dam before concrete pouring ceased on May 29, Overall, there is enough concrete in the dam to pave a two-lane highway from San Francisco to New York.
With most work finished on the dam itself the powerhouse remained uncompleted , a formal dedication ceremony was arranged for September 30, , to coincide with a western tour being made by President Franklin D.
Eastern Time. Most work had been completed by the dedication, and Six Companies negotiated with the government through late and early to settle all claims and arrange for the formal transfer of the dam to the Federal Government.
The parties came to an agreement and on March 1, , Secretary Ickes formally accepted the dam on behalf of the government. Six Companies was not required to complete work on one item, a concrete plug for one of the bypass tunnels, as the tunnel had to be used to take in irrigation water until the powerhouse went into operation.
There were deaths reported as associated with the construction of the dam. Tierney, fell from one of the two Arizona-side intake towers.
Included in the fatality list are three workers who took their own lives on site, one in and two in Ninety-six of the deaths occurred during construction at the site.
Workers alleged that this diagnosis was a cover for death from carbon monoxide poisoning brought on by the use of gasoline-fueled vehicles in the diversion tunnels , and a classification used by Six Companies to avoid paying compensation claims.
No deaths of non-workers from pneumonia were recorded in Boulder City during the construction period. The initial plans for the facade of the dam, the power plant, the outlet tunnels and ornaments clashed with the modern look of an arch dam.
The Bureau of Reclamation, more concerned with the dam's functionality, adorned it with a Gothic -inspired balustrade and eagle statues. This initial design was criticized by many as being too plain and unremarkable for a project of such immense scale, so Los Angeles-based architect Gordon B.
Kaufmann , then the supervising architect to the Bureau of Reclamation, was brought in to redesign the exteriors.
He designed sculpted turrets rising seamlessly from the dam face and clock faces on the intake towers set for the time in Nevada and Arizona—both states are in different time zones, but since Arizona does not observe daylight saving time , the clocks display the same time for more than half the year.
At Kaufmann's request, Denver artist Allen Tupper True  was hired to handle the design and decoration of the walls and floors of the new dam.
True's design scheme incorporated motifs of the Navajo and Pueblo tribes of the region. With the agreement of Kaufmann and the engineers, True also devised for the pipes and machinery an innovative color-coding which was implemented throughout all BOR projects.
True's work on the Hoover Dam was humorously referred to in a poem published in The New Yorker , part of which read, "lose the spark, and justify the dream; but also worthy of remark will be the color scheme".
Complementing Kaufmann and True's work, sculptor Oskar J. Hansen designed many of the sculptures on and around the dam. His works include the monument of dedication plaza, a plaque to memorialize the workers killed and the bas-reliefs on the elevator towers.
In his words, Hansen wanted his work to express "the immutable calm of intellectual resolution, and the enormous power of trained physical strength, equally enthroned in placid triumph of scientific accomplishment", because "[t]he building of Hoover Dam belongs to the sagas of the daring.
Surrounding the base of the monument is a terrazzo floor embedded with a "star map". The map depicts the Northern Hemisphere sky at the moment of President Roosevelt's dedication of the dam.
This is intended to help future astronomers, if necessary, calculate the exact date of dedication. To put such large bronzes into place without marring the highly polished bronze surface, they were placed on ice and guided into position as the ice melted.
The bas-relief on the Arizona elevator depicts, in his words, "the visages of those Indian tribes who have inhabited mountains and plains from ages distant.
Excavation for the powerhouse was carried out simultaneously with the excavation for the dam foundation and abutments.
The excavation of this U-shaped structure located at the downstream toe of the dam was completed in late with the first concrete placed in November Filling of Lake Mead began February 1, , even before the last of the concrete was poured that May.
In the latter half of , water levels in Lake Mead were high enough to permit power generation, and the first three Allis Chalmers built Francis turbine - generators , all on the Nevada side, began operating.
In March , one more Nevada generator went online and the first Arizona generator by August. By September , four more generators were operating, and the dam's power plant became the largest hydroelectricity facility in the world.
The final generator was not placed in service until , bringing the maximum generating capacity to 1, megawatts at the time.
The Hoover Dam is one of the most phenomenal structures in modern history. This feet long, feet thick, and feet high concrete behemoth holds back so much water that it deformed the earth's crust and caused small earthquakes in the decade after its construction.
Over workers died constructing the Hoover Dam — and legend has it, some of them are buried within its concrete facade.
Is there anything to these rumors? An enormous number of deaths Over people died in the construction of the Hoover Dam.
