Johnson’s Pond, also known as Flat River Reservoir, is a recreational gem located in Kent County. Damming the south branch of the Pawtuxet River near where it is joined by the Flat River created the 659-acre lake. Exactly when it was first dammed and by whom is lost in early American history.

Near the western shore, the George B. Parker Woodland Wildlife Preserve protects over 800 acres for the enjoyment of New England wildlife and birds. Within the preserve, many mysterious stone cairns are found, built in the wooded area by unknown prehistoric peoples. The structures are apparently related to other stone structures in New England built by an unknown extinct tribe. The City of Coventry has several preserved historic structures, including Spell Hall, and the General Nathanael Greene Homestead Museum. The General was second in command under George Washington during the Revolutionary War.
