Bathymetric Maps

Download available bathymetric maps (PDF).

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.

Plymouth Ponds & Lakes Stewardship Project & Pond Monitoring Program

In 2014 the Town of Plymouth Department of Marine and Environmental Affairs received $38,854 in grant funding from the Massachusetts Environmental Trust. This funding enables the Town and Project Partner UMASS Dartmouth - School of Marine Science and Technology (SMAST) to commence the Plymouth Ponds and Lakes Stewardship Program (PALS) and Pond Atlas for water quality analysis and reporting in 39 ponds throughout Plymouth. See additional information (PDF). In 2015 the following ponds are slated to be sampled and added to the Atlas: Little Sandy Pond, Lout Pond, Cooks Pond, Great Island Pond, Honeypot Lake, Island Pond (near Great Herring), Triangle Pond.
