1953 Map of Conowingo Dam

USGS Topo · Published 1954

About this map

Susquehanna River Conowingo Reservoir dominates this mid-century landscape, bisecting the borderlands between Maryland and Pennsylvania. This map captures the industrial and agricultural rhythm of the area just a few decades after the massive Conowingo Dam reshaped the river valley, showing the infrastructure of the Power Plant alongside rural life. In the Cecil County interior, settlements like Rowlandsville and Conowingo (PO) are connected by the Pennsylvania Railroad, while the Harford County side features the established village of Darlington. Local history is visible in the numerous country churches such as Hosanna Ch and St Patricks Ch, and the precise survey of the Mason and Dixon Line along the northern edge. The presence of the Susquehanna Power Company RR and various quarries near Oakwood reflects the era's reliance on both rail transport and local mineral extraction.
