Lake Springfield - Spaulding Dam Control Structure Rehabilitation

Work to create Lake Springfield initiated around 1932 on Sugar Creek with the construction of the Spaulding and Saddle Dams to form the lake. Five mechanical gates at the historic Spaulding Dam have provided level control for the 4,200-acre reservoir since its inception. After 70 plus years of continuous operation, the original Spaulding Dam gate mechanicals were deteriorating and nearing the end of their useful life. The design process to rehabilitate the five gate mechanicals was initiated in 2005 and project construction was completed in 2010. The design and construction team faced many challenges throughout the project including reusing as much of the historic structure as possible, choosing the optimum replacement gate system for the application, designing redundancy and reliability into the project, and interfacing the new gates with the Owner's existing control system. Permitting and maintaining continuous uninterrupted operation of the control structure proved to be significant project parameters as well.
