About this map

Schoharie Creek dictates the geography of this Catskill region, serving as the basin for massive utility and infrastructure projects that reshaped the valley. The map documents the complex water management system centered on the Gilboa Dam, which holds the Schoharie Reservoir at the southern edge, while the more recent Blenheim Gilboa Reservoir and its Upper Blenheim Gilboa Reservoir pumped-storage system dominate the central terrain.

Amidst these modern engineering feats, traces of earlier settlement remain visible in the hamlets of North Blenheim and Conesville. The landscape is dotted with ancestral markers such as the Shafer Cem, Kniskern Cem, and Rural Cem, providing critical data for genealogical research. Natural landmarks like Mine Kill Falls and Manorkill Falls punctuate the steep elevations of Blenheim Mountain and Brown Mountain, illustrating the high-relief topography that characterizes the Schoharie Valley.
