1978 Map of Dewey Lake

About this map

Jenny Wiley State Park dominates this 1970s landscape, where the impounded waters of Johns Lake wind through the narrow valleys of Floyd and Johnson Counties. The topographic record shows a region defined by heavy coal extraction, with numerous strip mines and industrial sites dotting the ridges above Johns Creek. Along the southwestern edge, the city of Prestonsburg serves as a local hub near the Levisa Fork, supported by the Chesapeake and Ohio railroad corridor. Smaller settlements like Lancer, Watergap, and Emma are clustered along the river and rail lines, while numerous family and community landmarks such as Wrights Chapel, Trimble Chapel, and the Endicott Cem provide essential data for genealogical research. The map also highlights recreational developments around the lake, including the Amphitheater and Brandy Keg Boat Dock near the Dewey Dam.
