Improved Roosevelt Dam The Theodore Roosevelt Dam is an example of the
redesign of an historic structure. Constructed between 1903 and 1911 by
the U. S. Reclamation Service, Roosevelt Dam, the largest masonry dam
in the world, is located at the confluence of the Salt River and Tonto
Creek in Arizona. During the 1970s, safety investigations revealed that
massive flooding or earthquakes posed a danger to the integrity of the
original structure. The Bureau of Reclamation (BOR) undertook its renovation
in 1984. When the project was completed in 1996, improvements included
raising the dam's height 77 feet, providing additional spillways, and
improving the dam's safety, flood control, and water storage capabilities.
BOR accomplished these improvements while preserving many of the original
design features of this historic landmark.
