| Roosevelt Dam impounds the Salt River east of Phoenix, Arizona. The masonry arch dam was one of the first major projects of the U.S. Reclamation Service (now the Bureau of Reclamation) and is named for President Theodore Roosevelt, who was instrumental in creating the federal agency. The dam was the world’s tallest masonry dam when it was completed in 1911. In 1996 the dam’s height was raised to 109 m (357 ft). |
