Mud Mountain Dam Fish Passage
T1-RJS Joint Venture (T1-RJS) team was awarded a top priority project to rehabilitate/upgrade several critical infrastructure elements required for the Mud Mountain Dam (MMD) fish passage facility. The existing fish passage facility is actually six miles downstream of MMD. This uniquely designed system is comprised of a barrier structure (owned by Cascade Water Alliance (CWA), a fish trap (owned by USACE), and a haul and release location upstream of the dam. The system maintains pink salmon migration and other species natural migration habits past MMD, and also allows the Muckleshoot Indian Tribe to gather brood stock for its adjacent hatchery.
Our team has been tasked with a very diverse scope of specialized and challenging elements of work, in order to meet or exceed the objectives of all stakeholders, and to ensure that the annual salmon run could proceed safely and efficiently.
