Dam it !
Built between 1905-1911, Theodore (Teddy) Roosevelt Dam is one of the first five federal projects ordered by the Reclamation Act of 1902. This masonry marvel impounds the Salt River primarily for storage purposes, irrigation water supply and flood control. In addition to cultivating the vital resource for agricultural purposes, the dam harnessed the pure power of water and has a hydroelectric generating capacity of 36,000 kW.
