The long-term performance of steel under extreme temperatures ensures the dam's structural reliability and durability
Dam replacement is more stable and will last 50 years longer than previous dam
Serves as a flood control tool, recreation venue, and an economic development center.
The $45 million Tempe Town Lake Dam is an engineering marvel as the country’s largest hydraulically controlled steel-gate dam. The dam receives flows from the Salt River as it passes through the City of Tempe, Arizona, forming what is known as “Tempe Town Lake.”
As a result of the Tempe Town Lake, Tempe now hosts many world class events, and people can take part in a variety of recreation opportunities. It has transformed a dry riverbed into a beautiful, relaxing community gathering place known throughout the world.
The selected replacement is a hydraulically operated steel gate system, consisting of eight 106-foot-long by 17-foot-tall steel gates supported by seven concrete piers, two abutment walls, and a 21-foot-thick concrete foundation. Gannett Fleming also prepared final design and construction documents, including geotechnical investigations, coordinated with the gate vendor and construction contractor, and obtained a dam safety permit from the Arizona Department of Water Resources.
