TEMPE, Ariz. --  Work to install the new dam on the west end of Tempe Town Lake is expected to begin this summer. Crews are now working in the river bottom to prepare the site for the start of this construction.

The City of Tempe is replacing the existing inflatable dam system with what is thought to be the world's largest hydraulically-operated steel gate dam. City officials call it a "reliable and cost-effective solution that's expected to last for decades."

The new dam will be located about 100 feet west of the current dam. A storm-water line will be relocated and new abutment walls will be built as first steps. The dam is expected to be operational by Dec. 28, 2015. 

Total project costs are estimated at $40.8 million. The city will pay for the dam using cash reserves and voter-approved bonds. This is the city’s most significant capital project since the construction of the lake itself, which opened in 1999.

An open house to provide information about this project will take place at Tempe Center for the Arts on April 23 from 6:00 to 7:30 p.m. Representatives from PCL Construction, Gannett Fleming and the City of Tempe will be on hand to answer questions about how the new dam works, an approximate construction time line, construction impacts and other issues.
