How many megawatts does Hoover Dam generate?
A dam's electrical output is partly a function of the height of its reservoir. More water equals more pressure, which equals more energy. The total capacity at Hoover is now 1,617 megawatts—a 20 percent decrease from its designed capacity of 2,080 megawatts.
How fast do the turbines spin at Hoover Dam?
180 rpmAs water rushes through the wicket gate, it flows past blades that spin the turbine and drive a rotor inside a generator, which then creates a spinning magnetic field to produce electricity. Hoover Dam has 17 turbines, each weighing about 700 tons, with generator shafts rotating at 180 rpm.
What does the Hoover Dam use to power its generators?
Near the bottom of the dam wall is a water intake. Gravity causes the water to fall through a sluice known as a penstock inside the dam. At the end of the penstock is a turbine which is turned by the fast-moving water. The shaft from the turbine goes up into the generator, which produces the power.

Why is Hoover Dam named Hoover Dam?
Hoover Dam is named in honour of Herbert Hoover, the U.S. president during whose administration (1929–33) construction began on the dam and whose work as commerce secretary in the 1920s secured agreements necessary for the project to proceed . Erected during the Great Depression, the dam was a major endeavour that employed thousands of workers; around 100 fatalities occurred during its construction. Although legislation passed by Congress in 1931 officially named the dam for Hoover, officials in the succeeding administrations of Franklin D. Roosevelt and Harry S. Truman referred to it as Boulder Dam, its name during the planning stages before construction. In 1947 Truman signed a congressional resolution restoring the structure’s formal name to official use.

How would a pump station help the dam?
The pump station, downstream, would help regulate the water flow through the dam’s generators, sending water back to the top to help manage electricity at times of peak demand. The net result would be a kind of energy storage — performing much the same function as the giant lithium-ion batteries being developed to absorb and release power.

Overview
Operation
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 1933 with the first concrete placed in November 1933. Filling of Lake Mead began February 1, 1935, even before the last of the concrete was poured that …
Background
As the United States developed the Southwest, the Colorado River was seen as a potential source of irrigation water. An initial attempt at diverting the river for irrigation purposes occurred in the late 1890s, when land speculator William Beatty built the Alamo Canal just north of the Mexican border; the canal dipped into Mexico before running to a desolate area Beatty named the Imperial Valley. …
Construction
Soon after the dam was authorized, increasing numbers of unemployed people converged on southern Nevada. Las Vegas, then a small city of some 5,000, saw between 10,000 and 20,000 unemployed descend on it. A government camp was established for surveyors and other personnel near the dam site; this soon became surrounded by a squatters' camp. Known as McKeeversville, the cam…
Environmental impact
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 construction of the dam has been implicated in causing the decline of this estuarine ecosystem. For six years after the construction of the dam, while Lake Mead filled, virtually no water reached the mouth of the river. The delta's estuary, whi…
Naming controversy
During the years of lobbying leading up to the passage of legislation authorizing the dam in 1928, 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 Boulder Canyon Project Act of 1928 (BCPA) never mentioned a proposed name or title for the dam. The BCPA merely allows the government to "construct, operate, and maintain a dam and incidental works in the main stream …
Recognition
Hoover Dam was recognized as a National Civil Engineering Landmark in 1984. It was listed on the National Register of Historic Places in 1981, and was designated a National Historic Landmark in 1985, cited for its engineering innovations.
