Scargo Lake, also known as Scargo Pond, is a 60-acre natural kettle-hole pond with an average depth of 25 feet and a maximum depth of 48 feet. The 1.3 miles of shoreline are moderately developed with beaches and permanent residences. The pond has an outlet to Sesuit Creek and Cape Cod Bay during high water periods. The terminal moraine of the glacier's retreat lies to the south, forming Scargo Hill, and resulting in numerous boulders on the southeast shoreline.

Scargo Lake is located between MA-6A and Scargo Hill Road and is easily reached off MA-6A. There are three town landings, all of which are suitable for launching light draft boats and canoes. Two are accessible via dirt roads immediately off Route 6A on the western side, and the remaining one on the northern cove can be reached from an unnamed road off the intersection of MA-6A and Sesuit Neck Road.
