Mirabel Fish Screen Ladder

The work consisted of construction of a vertical slot fish ladder, fish screen with 6 intake bays, and viewing gallery with 400 square feet of viewing windows. The project included a temporary dam and rock fish passage upstream of the Wohler Bridge, pipe pile foundation system, fish screen cleaning system with a vertical traveling brush and controller, dewatering of the river channel and groundwater as necessary to maintain dry working conditions. It also covered approximately one acre of previously developed land requiring earthwork removal in the riverbank to create facility access and maintenance roads.
