History: Mill Pond is located at the Harwich-Brewster border, east of the eastern end of Long Pond. The pond has been a focus of conservation efforts, with both Harwich Conservation Trust and Brewster Conservation Trust purchasing property to protect the pond’s water quality and sustain its access as a fishing pond.
Estimates of depth vary — the Cape Cod Pond Atlas shows maximum depth of 15 feet, while the Massachusetts Division of Fisheries and Wildlife bathymetry, shown below, gives a deepest point of 18 feet.
Mill Pond’s name derives from a windmill that was located on its northern shore, which was removed shortly after its roof was blown off during the great gale of 1816.
