About this map

The Cannonsville Reservoir dominates this landscape in the western Catskills, representing a mid-century transformation of the West Branch Delaware River valley. This 1965 survey documents the area shortly after the reservoir’s completion, showing the New York City Water Supply boundary surrounding the inundated basin. While the massive water body altered the geography, the surrounding towns of Sanford and Kelsey remain as anchors in the upland terrain.

Evidence of the region's earlier industrial and recreational life persists in the margins. The Erie-Lackawanna railroad line traces the southwestern corner through Sanford, while numerous small lakes like Crystal Lake and Silver Lake dot the western hills. The map also records the rural infrastructure of the era, from the Cannonsville Bridge and its associated Substation to the network of logging and quarry roads that weave through the Delaware State Forest. Local heritage is marked by several unnamed cemeteries and family-named landmarks like Dryden Brook and Travis Brook.
