The Town of Stonington contains a land area of 42.7 square miles, including over seven miles of frontage on Fisher's Island Sound.  It is the southeasternmost town in Connecticut.  The westernmost portions of the town are known as Mystic and Old Mystic.  A peninsula in the center of the shoreline contains the Borough of Stonington, a quasi-separate legal entity and the nearby village of Wequetequock.  The Village of Pawcatuck is located in the eastern part of the town, at the CT/RI state line, and contains the neighborhoods of Lower Pawcatuck, Clarks Village, Downerville and Stillmanville. The less densely settled Uplands are located along the northern edge of town.

Rivers define the town, forming its east and west borders. The tidal Pawcatuck River is shared with the town of Westerly, RI in the east, and flows 8 miles south to Little Narragansett Bay. The tidal Mystic River and Whitford Brook form the border to the west, along the towns of Groton and Ledyard.

Three main streambelt systems, listed from west to east, flow north to south in town. The east and west branches of Copps Brook feeds the Palmer and Mystic Reservoirs before flowing into Quiambog Cove. Stony Brook flows south from the Uplands through Silvias and Vargas Ponds to Stonington Harbor. Wheeler Brook in the Uplands flows east to Anguilla Brook. Anguilla Brook runs south through Anguilla Plains to Wequetequock or Chesebrough Pond and then flows over a 17th Century mill dam to Wequetequock Cove and Little Narragansett Bay.

Donahue or Oxecoset Brook also flows into the marshes of western Wequetequock Cove. Pequotsepos Brook runs from the northern hills of Mystic into Williams Cove at Mystic Harbor. The rivers all suffer from differing degrees of man-made restrictions such as dams, railroad tracks, Route 1, and Barn Island impoundments which restrict tidal flows into the upper bays and lead to conditions of poor water quality. Work is underway to remove some of these restrictions or to retrofit them with fish ladders.

The town has much perceived or undedicated open space, especially open fields or farmland, and work is underway to acquire their development rights - or the properties outright - so as to preserve the historic and scenic landscapes which are important both to wildlife and for our future food security.
