Completed in 1911 by the Bureau of Reclamation the Roosevelt dam once stood 280 feet high, 723 feet long at the crest. Today, the dam is 357 feet tall, holding back more than 1.6 million acre-feet of water at Roosevelt Lake, according to SRP. The Roosevelt Dam is a concrete gravity arch, located about 76 miles northeast of Phoenix and 30 miles northwest of Globe, Arizona. Serving mainly for irrigation, water supply, and flood control, the dam also has a hydroelectric generating capacity of 36 megawatts.Â
In 1888, Billy Breakenridge became surveyor for Maricopa County. He surveyed the Salt River for potential dam sites and in July 1889, he traveled with James McClintock, William J. Murphy, and John R. Norton to choose the best location. After a week on horseback, they reached Box Canyon, near the confluence of Tonto Creek and the Salt River. They recommended the location as the best site for a dam (Wikipedia).Â
