Duxbury Bay (Massachusetts)

The bay opens southerly toward Plymouth, Massachusetts between Captains Hill to the west and Saquish Head to the east.

The bottom is mostly shallow sand and mud flats exposed at low water with a few winding channels.

Several of these channels converge west of Clarks Island to form a small craft anchorage called the Cowyard approximately 200 yards (180 m) wide with a depth of 20–35 feet (6.1–10.7 m).

There is 5-foot (1.5 m) clearance under a 25-foot (7.6 m) fixed span in the Powder Point Bridge to access the northern end of the bay.

[2] In 1908 The United States Army Corps of Engineers dredged a 6-foot (1.8 m) channel to the Duxbury wharves.
