In this video segment, from Building Big: Dams, series host David Macaulay illustrates the forces that act on Hoover Dam, truly a "grande dame" among dams. Hoover Dam is no mere brute: a graceful curve complements its massive size. Since its completion in 1936, this elegant yet incredibly strong structure has provided electrical power, water for irrigation, and flood control. It literally fueled the growth of the modern American West.
