History
Artifacts dating back 450–1000 years, including hammer flakes and shell middens, have been found on the Washburn Island. As late as the early 19th century, some Wampanoags still lived around Bourne and Caleb ponds, at a spring supplying fresh water to both settlers and Native Americans.

The administrative, research, and education buildings are located in the historic buildings of the Sargent Estate. Purchased in 1987 by the Commonwealth, great care was given in restoring the buildings. The Quashnet River Property was also purchased in 1987 and incorporated into the Reserve. The Reserve and the Division of Fisheries and Wildlife manage the river property.
