Industrial Wonders: Hoover Dam

The Learning Channel, 10 p.m.

The building of huge Hoover Dam on the Colorado River, 1931-1936, two years ahead of schedule was a testament to American engineers’ ingenuity and know-how but also to the teamwork, “can-do” spirit and raw courage of America's workingmen. More than 16,000 men labored on the dam for an average of 62.5 cents per hour, or $1,825 per year, good money during the Depression. Ninety-six died in accidents, but that total does not include deaths from “natural” causes such as heart attack and heat exhaustion. Today the dam supplies water for tens of millions of Americans in the Southwest.
