Lake Mascuppic is a 209-acre, spring fed lake. It has a Massachusetts state boat ramp located in Dracut, although the bulk of the shoreline is within Tyngsborough. The waterfront is heavily developed, with the exception of the southwest shore, which falls within the Dracut State Forest. The lake is fully recreational and boat traffic can be heavy in the summer. The Lake Mascuppic Association, based in Tyngsboro, Massachusetts, is a not-for-profit, all-volunteer organization dedicated to maintaining Lake Mascuppic for the benefit of its users. Our activities promote safe boating, lake health and water quality, public health, recreational activities, and good stewardship practices.
