Ashumet Pond is a 203-acre natural kettle hole pond with an average depth of 23 feet and a maximum depth of 65 feet. The pond’s water sources are groundwater and an inlet from an abandoned cranberry bog. The pond is located just south of the Massachusetts Military Reservation (Otis Air National Guard Base) and is divided by the town line between Mashpee and Falmouth. The 2.5 miles of shoreline are heavily developed with year-round homes.

To get to Ashumet Pond from the Bourne Bridge, take MA-28 south to MA-151 east, then take a left onto Sandwich Road. The ramp is on the east side of the road near the intersection of Currier Road and Sandwich Road. A paved boat ramp with ample parking is provided by the Public Access Board and maintained by the Division of Fisheries and Wildlife.
