1952 Map of Quabbin Reservoir

About this map

The vast expanse of the Quabbin Reservoir dominates this central Massachusetts landscape, reflecting the massive mid-century transformation of the Swift River Valley. This revision, based on surveys from 1942 and 1952, captures the flooded valley where islands like Mount L and Russ Mtn rise from the water, marking what were once prominent highlands. Along the western shore, the Daniel Shays Highway traces the rugged terrain through New Salem, while the remnants of small communities such as Cooleyville and North Prescott remain visible on the upland fringes. The map illustrates a transitional era where the engineering of the Baffle Dam and the natural flow of Prescott Brook coexist. Topographical details such as Soapstone Hill and Prescott Hill provide critical context for local historians and genealogists looking to place family landmarks against the backdrop of this artificial inland sea.
