Winsor Dam

The Winsor Dam and the Goodnough Dike impound the waters of the Swift and Ware Rivers, forming the Quabbin Reservoir, the largest water body in Massachusetts. The dam is one of the largest in New England.

A hilly walkway leads up to the dam.

Walking across the dam is a popular activity in the park.

The 412 billion gallon reservoir is the largest man-made reservoir in the world devoted solely to drinking water supply.
From 1938-1946 four towns were flooded to create this vast reservoir. It supplies over 40% of Massachusetts with drinking water.

Water can form waves on windy days.
