History • Teddy Roosevelt signed the law in 1902 to start a dam and an artificial lakes in the western part of the US to stop run off and the waste of water in the winter season. • A dam is a barrier that impounds water or underground streams.
History • Reclamation began to build a dam after many farmers promised to pay for the stop of flooding and the availability to use water in a more safe and rapid way. The reclamation started to build what is now known as Hoover Dam. • Reclamation means non polluting electric power from great hydro plants
HOOVER DAM • Originally known as Boulder Dam. • The world's largest electric-power generating station. • The world's largest concrete structure. • Grand Coulee Dam in 1945. • Hoover Dam is currently the world's 35th-largest hydroelectric generating station. • Named after Herbert Hoover.
HOOVER DAM • In January 1922, Hoover met with the state governors. • Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming. • Colorado River Compact was signed on November 24, 1922. • Split the river basin into upper and lower halves. • Provide irrigation water flow, for flood control, and for hydroelectric-power generation
CONSTRUCTION FACTS • Capable of generating 2 million kilowatts sufficient for 1.7 million homes. • Has 17 generators. • Two cofferdams were constructed. • Four diversion tunnels were driven through the canyon walls. • There were 112 deaths associated with the construction of the dam.
POURING CONCRETE • 6 million tons of concrete where used. • Uneven cooling and contraction of the concrete. • 125 years would have taken to cool to ambient temperature. • To further cool the concrete each form contained cooling coils of 1 inch thin-walled steel pipe.
