Theodore Roosevelt Dam on the Salt River in Arizona, USA. Originally built between 1905 and 1911, the dam was renovated and expanded in 1989-1996. Until then, it was a National Historic Landmark. It serves mainly for irrigation, water supply, and flood control, and has a hydroelectric generating capacity of 36 megawatts. This photograph by Elton E Kunselman from 1916 presents an arial view of the dam. Completed at a cost of $10 million, it was the largest masonry dam in the world for its time with a height of 84 m and a length of 216 m, while Roosevelt Lake was for a time the world's largest artificial reservoir. The dam contributed more than any other dam in Arizona to the settlement of Central Arizona and to the development of large-scale irrigation there. | |
