arrowrock dam historical recognition

The Southern Idaho Section is pleased to announce Arrowrock Dam has been recognized as Idaho’s first ASCE National Historic Civil Engineering Landmark!

​The Arrowrock Dam, located 20 miles upriver from Boise, Idaho, serves as an essential water storage facility supplying irrigation water to thousands of acres of fertile farmland in the Treasure Valley. At the time of its dedication in 1915, the Arrowrock Dam was the highest dam in the world at 350 feet, a title it would hold until 1932. Civil Engineers tested the technological limits of the time to construct this engineering
marvel. ​The Arrowrock Dam served as a proving ground for design elements and construction methods that would later be incorporated into other large dams in the west. The dam was the first United States Bureau of Reclamation dam to use Ensign Valves to control the flow from the outlet works. While working on the Arrowrock Dam, Engineer Frank Crowe developed a grid system of delivering concrete pneumatically and an overhead cable system for rapidly delivering construction materials throughout the construction site. Crowe later went on to construct many more dams, including the Hoover Dam, where he utilized the systems he developed while working on the Arrowrock Dam. The Arrowrock Dam is included on the National Register of Historic Places in Idaho.

The Southern Idaho Section hosted a technical tour and dedication ceremony of Arrowrock Dam on August 25, 2016.

Website background photo

The Southern Idaho Section would like to give a special thanks to Charlie Bennett, Architectural Intern at Erstad Architects, for taking the beautiful photo seen as the background of this website. The photo was taken the morning after the Table Rock Fire in June of 2016, which draped the Boise foothills in a blanket of smoke. Charlie was kind enough to grant the SIS permission to use his photo for the purpose of this website.
