Indian Ponds Association
Protecting Mystic Lake, Middle Pond, and Hamblin Pond since 1958
The three interconnected 100+-acre ponds in Marstons Mills, Massachusetts -- Mystic Lake, Middle Pond, and Hamblin Pond -- are, together, the Indian Ponds. They're kettlehole ponds, formed by pieces of ice left behind when the glaciers receded, and form an ecosystem that supports wildlife in, on, and off the water. They're also an integral part of the local community, and residents and visitors use the ponds for swimming, fishing, and boating year-round.
