Roosevelt Lake Visitor Center


The Theodore Roosevelt Dam, constructed 1903-1911, was the first multipurpose project built by the U.S. Bureau of Reclamation and actually predates Arizona statehood. Its unique cyclopean-masonry design resulted in its being listed in the National Registry of Historic Places as well as being named a National Historic Engineering Landmark. The structure recently underwent a nine-year renewal project. Improvements included construction of the longest two-lane, single-span, steel-arch bridge in North America, spanning some 1,080 feet across Roosevelt Lake. The reservoir has the greatest storage capacity of the six Salt River Project lakes.

Fun Fact:At the time it was built, the Theodore Roosevelt Dam was the world's largest all-masonry dam, made of huge, hand-hewn stones. A $430 million renovation project added 444,000 cubic yards of concrete to the dam (enough to pave a two-lane road from Phoenix to Tucson) and 6.7 million pounds of reinforcing steel (849 miles long if placed end to end).
