Theodore Roosevelt Dam is a dam on the Salt River located northeast of Phoenix, Arizona. The dam is 357 feet (109 m) high and forms Theodore Roosevelt Lake as it impounds the Salt River. Built between 1905 and 1911, the dam was renovated and expanded in 1989–1996. The dam is named after President Theodore Roosevelt. Serving mainly for irrigation, water supply, and flood control, the dam also has a hydroelectric generating capacity of 36 megawatts.
