Dennis pond encompasses approximately 12 acres and was man made. It was created in the early 1800s by Henry Clark to power a mill on the corner of Willington Ave and Westford Ave. It is approximately 200 feet wide and 2500 feet long.

The town purchased the pond from George Schofield for the purpose of a public park that is exclusive to Stafford residents. It is a conservation area that is looked after by the Stafford Conservation Commission.

The pond was used to harvest ice for refrigeration prior to the invention and wide adoption of the refrigerator. There is the remains of the ice house where the harvesting happened on the eastern side of the pond.
