This project would dredge Breaux Pass and Cul-de-sac Pass within the Atchafalaya Delta Wildlife Management Area in order to enhance access for hunters, anglers, and wildlife viewers to the interior marsh. A floating bucket dredge would be used to excavate each pass, as follows: • Dredging in Breaux Pass would include excavation of approximately 25,000 cubic yards of material (2,000 feet long, 80 feet wide, and 10 feet deep). Dredge materials from Breaux Pass would be placed along the south bank of the pass (see Figure 3.3-9). The dredging and placement area footprints for Breaux Pass would not exceed approximately 15 acres of open/in-water areas. • Dredging in Cul-de-sac Pass would include excavation of approximately 31,000 cubic yards of material (4,000 feet long, 50 feet wide, and 10 feet deep). Dredge spoils from Cul-de-sac Pass would be placed in alternate deposits along both banks of the pass. The dredging and dredge spoil footprints for Cul-de-sac Pass would not exceed approximately 8 acres of open/in-water areas. Dredging at Breaux and Cul-de-sac Passes would result in deeper and wider passes than currently exist, allowing boats deeper draft space, which also would accommodate a greater diversity of boat types and sizes.
