This project was mandated by the Colorado Division of Water Resources to provide a safer spillway for the dam constructed in the early 1900s. This new spillway will accommodate a 500 year flood event.
Connell was contracted to excavate for the new spillway and dispose of the excavated material to create a berm between the spillway and the existing dam. Work included 200,000 CY of channel excavation, the installation of two concrete spillway control structures with sheet piling and articulated concrete block armoring (appx. 27,800 SF) The project also included, excavation and backfill of structures, final grading, topsoiling and revegetation.
