2019 Map of Grahamsville

About this map

Grahamsville and the eastern reaches of the Rondout Reservoir anchor this 2019 survey of the Catskill region at the Sullivan Co and Ulster Co border. The landscape is defined by the critical infrastructure of the New York City water supply system, most notably the subterranean path of the Neversink-Rondout Aqueduct which traverses beneath Thunder Hill. Along the southern edge, the Neversink River flows toward Woodbourne, while the village of Hasbrouck sits near the confluence of Wynkoop Brook. The map reveals a mix of dense forest and valley settlements, where older landmarks like the Grahamsville Rural Cem persist alongside the small hamlets of Curry and Unionville north of Chestnut Creek. This topography illustrates the enduring relationship between the Catskill terrain and the engineered waterways that have reshaped local geography since the mid-20th century.
