Savery Pond forms the headwaters of a creek informally known as Herring Brook, one of two fresh surface-water inputs to the Ellisville Marsh Estuary.  It has an area of 29 acres, average and maximum depths of 7 and 12.5 feet (respectively), and qualifies as a “Great Pond” as designated by the State of Massachusetts. The pond is spring-fed by local groundwater, with surrounding land uses including residential, forest, cranberry bogs, and a commercial campground (primarily used by RVs). About 11 acres of commercial cranberry bogs operated on the pond for over 70 years, until recent changes in ownership converted one bog to a conservation area and the other to non-commercial status. People currently use the pond for fishing and recreation; however, Savery Pond provides key ecological functions and plays a significant role in the ecology of the Ellisville Watershed.
