Wellfleet Harbor Maintenance Dredging

The Wellfleet Harbor FNP consists of an 10 foot deep Mean Lower Low Water (MLLW) by 125 feet wide from the outer harbor extending 0.8 mile northeasterly to the town landing and anchorage basin of the same depth with the dimensions of 800 feet by 500 feet at the head of the channel. The proposed work consists of dredging approximately 162,000 cubic yards (cy) (including required dredge and overdepth) of fine grained sands and silts from the 10 foot entrance channel and 10 foot anchorage of the Wellfleet Harbor FNP. The 10 foot channel and 10 foot anchorage will be dredged to the authorized project depth, plus allowable one foot allowable overdepth. The mechanical dredge will remove material from the shoaled portions of the Wellfleet Harbor channel/anchorage, and transport the material in scows to the Cape Cod Bay Disposal Site (approximately 15 nautical miles away to the west). The allowable dredging window is between Oct 1 and December 15, 2020. Additional work includes removal of derelict moorings. The work will require significant coordination around the tide cycles.
