1953 Map of Conowingo Dam

About this map

The Susquehanna River Conowingo Reservoir dominates this landscape, held back by the massive Conowingo Dam and its adjacent Power Plant. This 1953 survey, with revisions from 1970, captures the border region where the Mason and Dixon Line separates Pennsylvania from Maryland. The shoreline is marked by topographic landmarks like Wildcat Point and Bald Friar, while the river itself contains Rowland Island and Sterret Island. Moving inland, the map shows a network of small crossroads and rural centers such as Darlington, Oakwood, and Berkley. Genealogists will find numerous family and community landmarks, including St Patricks Cem, Bethesda Ch, and Grace Ch. Industrial and transportation features of the era are evident through the Pennsylvania Railroad tracks and the presence of a Quarry near the river's edge, reflecting the region's reliance on both the waterway and rail for transit and commerce.
