American Constrution Co. began an annual maintenance dredging project of the federal navigation channel in Grays Harbor Inner Harbor in July.
Under the $3.1 million contract American began removing 500000 cubic yards in the inner harbor near Aberdeen Washington scheduled to work through September 30. The dredge Patriot is placing material at the existing South Jetty nourishment site and the Washington State Department of Natural Resources-manged Point Chehalis open-water disposal site.
Inner harbor dredging is confined to the currently maintained -36 feet mean lower low water or MLLW depth. As part of the Grays Harbor Navigation Improvement Project a contract to dredge to the fully authorized -38 feet MLLW is out for bid. Corps officials expect to begin the next round of dredging operations in October including the authorized additional two feet in the vicinity of South Reach upstream to Cow Point Reach where the Port of Grays Harbor Terminal 4 is located.
