This report discusses measurements of the structural behavior of Fontana Dam. It is related to a report previously issued by TVA on the structural behavior of Norris and Hiwassee dams.

This report constitutes a detailed account of the more important results of the programs of testing and observations upon the structural behavior of Norris and Hiwassee Dams. These programs were initiated during the construction period for the purpose of guiding operations, and continued after the respective dams were placed in service. The study after construction was aimed at securing knowledge of conditions that might influence the life period and the economy and safety of the structures. The information obtained at Norris was of considerable value in the design and construction of Hiwassee Dam and similar benefits were realized at Fontana Dam from the investigations at Hiwassee.
