The Hoover Dam (Building America: Then and Now)

Buy
The time was the early 1930s, the president was Herbert Hoover, and the situation in the United States looked bleak. The stock market had crashed in 1929, and most Americans were hurt by the Great Depression, which left a majority of them jobless, homeless, and penniless. But in the West, a beacon of hope was in the works— a major structure that would symbolize the nation’s technological prowess. That structure, built as graceful as it was strong, would come to be known as the Hoover Dam.

In the dry western United States, water resources and water rights had almost always been an issue. For this growing area of the country, water for drinking and irrigating land was an everincreasing necessity. The United States Reclamation Service was formed to help deal with these concerns. This government entity and its engineers would come to play a great part in the construction of the Hoover Dam.
