The Saugatuck Reservoir is a reservoir in Fairfield County, Connecticut, United States, that straddles the border between the towns of Redding, Weston, and Easton. Its completion is marked by the creation of the Samuel P. Senior dam of the Saugatuck River in January 1942, and provides water to several of the nearby towns. The reservoir is surrounded by the Centennial Watershed State Forest and a small section of the Trout Brook Valley State Park Reserve on the southeast end of the reservoir.
