Theodore Roosevelt Dam, the first major structure constructed by the Bureau of Reclamation on the Salt River Project, is located about 76 miles northeast of Phoenix and 30 miles northwest of Globe, Arizona. The dam, completed in 1911, was subsequently modified between 1989 and 1996. The original dam was a cyclopean, rubble-masonry, thick-arch structure that spanned the Salt River to form a reservoir of 1,381,580 acre-feet. It was 280 feet high, 723 feet long at the crest, and contained 355,800 cubic yards of masonry,

In 1936, the spillways were modified by lowering crests 6 feet to increase their capacities, and installing individual gate hoists, operating motors, and two 5-kilovolt-ampere gasoline-engine driven generators.

From 1989 to 1996, the dam was modified by the Bureau of Reclamation. The modification raised the dam 77 feet in elevation and made the dam a concrete-gravity arch dam, increasing its water conservation storage capacity by 20 percent, adding flood control space to the reservoir, and addressing concerns about its safety as well as the safety downstream dams. In addition to raising the dam's height, the modification included construction of two new spillways, installation of new outlet works, and powerplant modifications. Also, existing recreation facilities at Roosevelt Lake were improved, and new recreational facilities were constructed.
