1965 Map of Cannonsville Reservoir

About this map

Cannonsville Reservoir dominates the landscape of western Delaware County, its creation having fundamentally altered the valley of the West Branch Delaware River. This 1965 survey records the terrain shortly after the reservoir’s completion, showing the submerged landscape of former valley farms and the realignment of infrastructure. Small settlements like Kelsey and Apex sit on the upland fringes, while the Erie-Lackawanna railroad tracks trace the southeastern edge through Kerry Siding and Faulkner. The map reveals a transition from traditional agricultural land use to recreation and resource management, evidenced by Kingswood Camp, Camp Hilltop, and expansive tracts of the Delaware State Forest. Notable upland water bodies such as Crystal Lake, Columbia Lake, and Silver Lake remain untouched by the reservoir, while numerous quarries and the NY City Water Supply boundary line highlight the area's role in industrial and metropolitan utility.
