Dredging of the Waterway 9-foot Channel Project is generally required at 5 to 15 sites, and the volume of material dredged is approximately 250,000 cubic yards per year.
Due to the large sediment load carried by the waterway and continually changing flows, specific dredging locations and quantities to be dredged vary from year-to-year.
The dredged material is usually removed from the navigation channel by a contractor hydraulic cutterhead dredge and discharged to placement sites by floating pipeline. The contract dredge is a 14- to 16-inch hydraulic dredge.
Under optimum conditions, the dredge can pump as much as 350 cubic yards per hour as far as 5,500 feet, including 1,500 feet inland.
