Rev. Sun Myung Moon commented,
- Hoover Dam was constructed using the most excellent technology available 70 years ago. It dams the Colorado River, which has flowed for millions of years, and provides water to millions of acres of land. In its time, Hoover Dam was a modern miracle and combined technologies from Europe and America. The deserts could become green land because of this. Seven states of the West have a major water problem, and the Hoover Dam could address this problem. 
Liberal Attempt to Rename Dam
Just as liberals opposed the naming of National Airport in D.C. after the former President Ronald Reagan, liberals also opposed naming this Dam after President Herbert Hoover, even though the engineer Hoover was the driving force behind the project:
|“|| On May 8, 1933, Harold Ickes, Franklin Roosevelt's Secretary of the Interior, decided that the name of the dam should be 'Boulder Dam', its original name. The reason for this was no doubt political.
On April 30, 1947, the resolution renaming the dam back to Hoover Dam was passed by congress and signed by President Harry S Truman.
