Sesachacha Pond is Nantucket's largest kettle pond, located on the eastern side of the island. It is a significant body of brackish water, covering about 280 acres and reaching depths of up to 43 feet. The pond is surrounded by conservation land, including the Sesachacha Heathlands Wildlife Sanctuary owned by the Massachusetts Audubon Society. This natural haven is home to a variety of wildlife, including striped bass, bluefish, and numerous bird species like ospreys and herons. The pond is also a popular spot for bird watching and offers a glimpse into Nantucket's rich ecological heritage.
The area around Sesachacha Pond is relatively secluded, with most of its shores sparsely populated by seasonal houses. Access to the pond is facilitated by the Nantucket Land Bank, which provides public access points. The pond's unique environment and its connection to the Atlantic Ocean via a narrow barrier beach make it a fascinating place to explore.
Historically, Sesachacha Pond has been opened to the ocean to promote fish runs and maintain ecological balance, although this practice has been regulated since the 1980s due to environmental concerns.
