HOUSTON – Today, the U.S. Army Corps of Engineers Galveston District (USACE Galveston) switched the flow of water at Addicks Dam to new outlet control structures, constructed as part of a $75 million contract awarded to Granite Construction Company to improve and modernize Addicks and Barker Dams. USACE Galveston had already cut over to new outlet control structures at Barker Dam on February 14. The new structures have been under construction since 2015 and will replace the originals built in the 1940s. Completion of the entire contract is expected in summer 2020.
