  • 3. Continued<br />The dam now converts the flow of the river into 2.4 megawatts of energy.<br /> Most of the energy is routed to southern California and Nevada.<br /> At the time the dam cost 49$ million to construct.<br /> The dam is 660 ft thick and is 1244 ft long. <br />The dam impounds the Colorado river.<br />
  • 4. Pictures of the Hoover Dam <br />
  • 5. About the Construction of the Hoover Dam<br />Geological specialists inspected the volcanic bedrock and found fault lines that were solid enough to support the structure.<br /> Also they sent out surveying parties to make contour maps showing that the area would hold 31 million acre feet of water. <br />
  • 6. Continued<br />The office engineering staff was busy making system analyses, drawings, specifications, schedules, and cost estimates.<br /> The work on the Dam was finished in the late 1930’s which was six months ahead of the projected time. <br />
  • 7. Achievements of the Hoover Dam<br />At the time of its completion the Hoover Dam was the world’s largest concrete structure.<br />It held that until 1942 when the Grand Coulee Dam opened. <br />It was also, at the time, the largest public-works program in U.S. history. <br />
  • 8. Continued<br />The Hoover Dam help reclaim California’s flood-prone Imperial Valley, it improved water supply to the seven Colorado River-basin states, and generated electric power for Southern California.<br />
  • 9. Pictures of the Hoover Dam<br />
  • 10. Facts About the Hoover Dam<br />The Hoover Dam is a concrete gravity-arch dam in the Black Canyon of the Colorado River.<br /> It is on the border between Arizona and Nevada.<br /> The Dam is named after Herbert Hoover who played a big role in its construction, first Secretary of Commerce, and the President of the United<br />
  • 11. About the Reservoir<br />Lake Mead is the reservoir created behind the dam.<br />It was named after Elwood Mead, who oversaw the construction of the dam. <br />Before the construction, the Colorado River Basin periodically overflowed its banks when snow from the Rocky Mountains melted and drained into the river.<br /> The floods endangered downstream farming communities. <br />The dam made it possible for the expansion of irrigated farming in the parched region. <br />It also provided a dependable supply of water for Los Angeles and Southern California communities.<br />

  • 13. Reasons why I chose the Hoover Dam<br />I chose this because it was one of the biggest achievements of the decade.<br />Also I thought this was one of the most interesting topics out of the list.<br />Lastly I wanted to learn more about this topic.<br />
