When a Six Moorhuhn Spiele manager altered working times to force workers to take lunch on their own time, workers responded with a strike. Once the Boulder Corona Zahlen Zypern project was approved, officials decided the dam would be a single arch-gravity dam with the width of ft m of concrete Sportingb the bottom and 45 ft 14 m at the top.
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 smaller generators were used to serve smaller communities at a time when the output of each generator was dedicated to a single municipality, before the dam's total power output was placed on the grid and made arbitrarily distributable.
Before water from Lake Mead reaches the turbines, it enters the intake towers and then four gradually narrowing penstocks which funnel the water down towards the powerhouse.
The entire flow of the Colorado River passes through the turbines. The spillways and outlet works jet-flow gates are rarely used. The maximum net generation was The amount of electricity generated by Hoover Dam has been decreasing along with the falling water level in Lake Mead due to the prolonged drought in the s and high demand for the Colorado River's water.
Lake Mead fell to a new record low elevation of 1, Control of water was the primary concern in the building of the dam.
Power generation has allowed the dam project to be self-sustaining: proceeds from the sale of power repaid the year construction loan, and those revenues also finance the multimillion-dollar yearly maintenance budget.
Power is generated in step with and only with the release of water in response to downstream water demands. Lake Mead and downstream releases from the dam also provide water for both municipal and irrigation uses.
Water released from the Hoover Dam eventually reaches several canals. The Colorado River Aqueduct and Central Arizona Project branch off Lake Havasu while the All-American Canal is supplied by the Imperial Dam.
Electricity from the dam's powerhouse was originally sold pursuant to a fifty-year contract, authorized by Congress in , which ran from to In , Congress passed a new statute which set power allocations to southern California, Arizona, and Nevada from the dam from to The new arrangement began on October 1, The Bureau of Reclamation reports that the energy generated under the contracts ending in was allocated as follows: .
Tourists gather around one of the generators in the Nevada wing of the powerhouse to hear its operation explained, September The dam is protected against over-topping by two spillways.
The spillway entrances are located behind each dam abutment , running roughly parallel to the canyon walls. Each gate weighs 5,, pounds 2, metric tons and can be operated manually or automatically.
Gates are raised and lowered depending on water levels in the reservoir and flood conditions. The large spillway tunnels have only been used twice, for testing in and because of flooding in Both times, when inspecting the tunnels after the spillways were used, engineers found major damage to the concrete linings and underlying rock.
In response to this finding, the tunnels were patched with special heavy-duty concrete and the surface of the concrete was polished mirror-smooth. The damage, also due to cavitation, led to the installation of aerators in the spillways.
There are two lanes for automobile traffic across the top of the dam, which formerly served as the Colorado River crossing for U.
Route Pending the completion of the bypass, restricted traffic was permitted over Hoover Dam. With the opening of the bypass, through traffic is no longer allowed across Hoover Dam; dam visitors are allowed to use the existing roadway to approach from the Nevada side and cross to parking lots and other facilities on the Arizona side.
Hoover Dam opened for tours in after its completion, but following Japan 's attack on Pearl Harbor on December 7, , it was closed to the public when the United States entered World War II, during which only authorized traffic, in convoys, was permitted.
After the war, it reopened September 2, , and by , annual attendance had risen to , The dam closed on November 25, , and March 31, , days of mourning in remembrance of Presidents Kennedy and Eisenhower.
In , a new visitors' center was built, and the following year, visits exceeded one million for the first time. The dam closed again to the public on September 11, ; modified tours were resumed in December and a new "Discovery Tour" was added the following year.
As a result, few of True's decorations can now be seen by visitors. The only self-guided tour option is for the visitor center itself, where visitors can view various exhibits and enjoy a degree view of the dam.
The changes in water flow and use caused by Hoover Dam's construction and operation have had a large impact on the Colorado River Delta.
The Colorado River had experienced natural flooding before the construction of the Hoover Dam. The dam eliminated the natural flooding, threatening many species adapted to the flooding, including both plants and animals.
During the years of lobbying leading up to the passage of legislation authorizing the dam in , the press generally referred to the dam as "Boulder Dam" or as "Boulder Canyon Dam", even though the proposed site had shifted to Black Canyon.
The BCPA merely allows the government to "construct, operate, and maintain a dam and incidental works in the main stream of the Colorado River at Black Canyon or Boulder Canyon".
When Secretary of the Interior Ray Wilbur spoke at the ceremony starting the building of the railway between Las Vegas and the dam site on September 17, , he named the dam "Hoover Dam", citing a tradition of naming dams after Presidents, though none had been so honored during their terms of office.
The health and safety of the public and the people working at the Hoover Dam continues to be our number one priority. We look forward to sharing this iconic engineering masterpiece with you.

Tour Information. Jameson found himself on the wrong end of a tumult of recently poured concrete. When a concrete form gave way, the wet concrete slid down the side of the Hoover Dam, covering Anderson and at least one other worker.
Anderson did not survive. Sixteen hours after the fatal accident, workers removed his body from the site.
Workers continue to speak of buried bodies Those constructing the Hoover Dam not only failed to squash rumors of individuals buried inside during construction, but often exacerbated the tales.
In the mids, Todd King, a University of Nevada Professor, conducted interviews with several individuals who worked on the Hoover Dam to learn the truth behind their accounts.
Though some of the stories of burial told by the elderly gentlemen sounded plausible to King, not one of the workers interviewed witnessed a person purposefully buried amidst the construction of the Hoover Dam.
Six bodies buried in Montana's Fort Peck Dam While it seems like no one is buried in the Hoover Dam, a structural failure caused thirty-four workers to be buried in the debris of Montana's Fort Peck Dam.
When it was finished in , the Hoover Dam was remarkable not only for having completed construction a full two years ahead of schedule, but also for its unprecedented stature.
