The Quabbin Reservoir in central Massachusetts was created in 1938 to supply the state's growing population with a source of drinking water. In order to create the reservoir, it was necessary to dam three branches of the Swift River, and to flood the valley which was home to five small towns- Dana, Enfield, Greenwich, Prescott, and parts of New Salem, all of which now exist underwater. More than two thousand people were displaced when the Quabbin Valley was flooded, and now these former towns are only accessible through memories, SCUBA equipment, or a time machine.The Lost Towns of the Quabbin Valleypresents rare photographs of town life, including images of students at the first Hillside School and Dr. Mary Walker, a Congressional Medal of Honor recipient and Greenwich summer resident. The images are drawn from the archives of the Swift River Valley Historical Society. Although the towns are gone, their stories are alive and well.
