Turnpike Lake covers an area of about 77 acres and has a maximum depth of 18 feet. The lake is popular for recreational activities such as fishing, boating, swimming, and picnicking. 

Two dams on Turnpike Lake will be receiving much-needed repairs. The dams play an important role in controlling water levels in the lake and have needed repair for a long time, according to Marcia Benes, founder and president of Natural Resources Trust of Plainville, which owns the property.

There is a car-top boat launch from Shepard Street. Car top boats and light trailer boats access on gravel ramp. Use care since the road is used as a shortcut by many people and the launch is directly on the road.
