NCM performed work at Little Goose Lock and Dam that included the installation of a boat barrier system and trash shear boom above the dam. The boat barrier system is designed to prohibit the entry of recreational craft and debris from entering the forebay, spillway gates and power unit intakes. The installation of the boat barrier system consisted of the placement of precast concrete anchors at the river bottom, assembly and installation of floating Boatbuster buoy strings, as well as the installation of a floating work boat gate for maintenance and long term service access. The precast anchors varied in depth from 40 to 130 feet of water. A total of 25 concrete anchors were installed along with stackable supplemental weights. The weight of the concrete anchors are approximately 43,000 pounds and the supplemental weights are approximately 48,000 pounds.
