726.4 feet high (221 m)
1,244 feet wide (379 m)
660 feet (203 m) thick at the base
45 feet (13 m) thick at the top
$165 million dollars to build
4.5 years to build
4.4 million yards of concrete used for construction
March 1931 building began
September 30, 1935 President Franklin D. Roosevelt dedicated the completed dam
Powerhouse
17 generators
4+ billion kilowatt hours produced each year
10 acres of floor space
Power used by:
56% California
25% Nevada
19% Arizona
Lake Mead
6.5 years to fill (A slow filling process was required to lessen the pressure change on the dam and to help prevent small earthquakes due to land settlement.)
589 feet (181 m) at the deepest point
247 square miles in size
110 miles (176 km) long
Largest man made reservoir in the United States

Kaustubh KatdareBoy! I've always wondered, how do they really start constructing any dam? I mean, what's the first phase of construction? -
CIVILPRINCESSFirst is digging another tunnel through which the water can flow and dewatering the area of construction. This is what I learnt from some dam construction. the flow of water into the main channel is prevented by building a cofferdam (just a temporary dam).
Then the normal construction is carried on 😀 -
FeatherWhat my friend here is saying is right. To build a Dam the engineers must first de-water the part of the river valley in which they wish to place the dam. This is usually achieved by diverting the river through a tunnel. The tunnel is built through one side of the valley around the planned construction area. A series of holes is drilled in the rock. Explosives are placed in the drill holes, blasting takes place and broken rock is then removed. This procedure is repeated many times until the tunnel is completed. Diversion tunnels are often lined with concrete.
