Maps dating from the 1970's through 2020 have been compiled into one document. Several color bathymetric maps were released by the Massachusetts Division of Fisheries and Wildlife in January of 2020 and are the most accurate contour measurement map produced to date. These ponds' older counterpart maps have been retained in the document as well.
