DIVERSION DAM FISH LADDER MODIFICATIONS

Other work consisted of construction of a new concrete fish ladder, installation of spillway inflatable gates with control structure, slide gates, metal building, electrical and automated trash rake system. The project occurred over a 5-month water window that required Bear Creek to be diverted around the work zone in two phases, while providing fish passage during the entire project.
