An image showing an aerial view of Davis Dam on the Colorado River. Located within Pyramid Canyon between Arizona and Nevada, Davis Dam was constructed on the Colorado River 67 miles downstream from Hoover Dam. Due to the Mexican Treaty of 1944, the United States was required to construct Davis Dam for regulation of water to be delivered to Mexico.

The face of Hoover (Boulder) Dam, taken from the downstream side of the dam on the Nevada side. May, 1947. The intake towers are visible in the background. The Arizona spillway is visible at the far right of the photograph. During the years of lobbying leading up to the passage of legislation authorizing the dam in 1928, Hoover Dam was originally referred to "Boulder Dam" or as "Boulder Canyon Dam", even though the proposed site had shifted to Black Canyon. The Boulder Canyon Project Act of 1928 (BCPA) never mentions a proposed name or title for the dam. When Secretary Wilbur spoke at the ceremony starting the building of the railway between Las Vegas and the dam site on September 17, 1930, he named the dam "Hoover Dam", citing a tradition of naming dams after Presidents, though none had been so honored during their terms of office. After Hoover's election defeat in 1932 and the accession of the Roosevelt administration, Secretary Ickes ordered on May 13, 1933 that the dam be referred to as "Boulder Dam". In the following years, the name "Boulder Dam" failed to fully take hold, with many Americans using both names interchangeably and map makers divided as to which name should be printed. In 1947, a bill passed both Houses of Congress unanimously restoring the name to "Hoover Dam".
