Hoover Dam, Narrated by Michael Green

[00:00:05]The plans for Hoover Dam predated the Great Depression, but it became a major public works jobs project.

[00:00:13]About 21,000 helped dam the Colorado on the Nevada-Arizona border between 1931 and 1936.

[00:00:21]The result was water and electricity for the rapidly growing Southwest, a 727-ft high dam with 3.2 million cubic yards of concrete.

[00:00:32]The danger and speed of construction cost at least 96 lives.

[00:00:38]At the dedication, President Franklin Roosevelt said, "I came, I saw, and I was conquered as everyone would be who sees for the first time this great feat of mankind." Today, about 1.3 million people get electricity from it, and 7 million tourists visit it annually.
