Centennial Watershed State Forest is a Connecticut state forest of more than 15,000 acres with larger parcels located in the towns of Easton, Newtown, Redding, and Weston. Dozens of other properties are strung throughout much of Southwestern part of the state. In 2002, the lands were acquired from the Aquarion Water Company by the state in partnership with The Nature Conservancy. Those three entities continue to manage the property by committee. The forest was named in honor of the hundredth anniversary of the state forest system.
