1977 Map of Occoquan

About this map

The Occoquan River and its massive Occoquan Reservoir dominate this aerial survey, illustrating the complex intersection of natural drainage and rapid suburban expansion in Prince William County. The 1977 photoimagery reveals the intricate street patterns of growing residential hubs like Dale City and Woodbridge, which contrast sharply with the winding, wooded banks of Sandy Run. This orthophotoquad is particularly revealing for local historians, as it shows the physical footprint of late-1970s development alongside established community nodes such as Farrs Corner and Agnewville. The transition from rural forest to dense neighborhood is starkly visible, especially near the shores of Lake Omiscol, providing a precise record of the landscape before further modern densification.
