2021 Map of Quabbin Reservoir

About this map

Quabbin Reservoir dominates this central Massachusetts landscape, where rising waters have transformed former uplands into a complex system of islands and peninsulas. The modern geography reveals the remnants of historical settlements like North Prescott and Cooleyville, now situated near the protected wilderness of the Prescott Peninsula. Along the western heights, the New England National Scenic Trl traverses the high ground of Prescott Ridge and Packard Mtn, offering views across the flooded valley. Local history is anchored by the Mountain View Cem near the junction of N Prescott Rd and Osborne Rd. The map also illustrates the steep topography of The Gorge and various islands such as Mt Zion, Snell Island, and Hamilton Island, which were once prominent hills overlooking the Swift River valley before its inundation.
