President and Rough Rider leader Theodore Roosevelt authorized the Newlands Reclamation Act in 1901 for constructing large-scale water control systems in the western US. He traveled to Arizona to speak at the March 18th, 1911 dedication of Roosevelt Dam, the first dam to control the Salt River. Now in a system with four other dams, it helps prevent droughts and flooding. | Date: 1911 | Source: Library of Congress | Rights: Library of CongressDownload Original File
