Massawepie Lake is located in the town of Piercefield, in southern St. Lawrence County, New York, approximately 12 miles (19 km) southwest of the village of Tupper Lake, New York.

Fish species present in the lake are lake trout, smallmouth bass, whitefish, walleye, yellow perch, black bullhead, rock bass, and white sucker.

[3] One of the most notable geographic features is the Massawepie Mire located immediately to the south of the lake.

Hundreds of acres in size, the bog is one of the largest of its kind in the Eastern United States and is almost entirely on the Boy Scout camp's property.

In the days before air-conditioning, upperclass residents of New York City would retreat to the Adirondacks to escape the summer heat.
