1986 Map of Piqua
USGS Topo · Published 1986About this map
The Indiana Ohio state line bisects this 1986 survey, capturing a vast agricultural landscape anchored by the manufacturing and transit hubs of Piqua and Troy. The region is defined by a dense network of river systems, including the Stillwater River and the Miami River, which supported early industrial growth. The Miami Conservancy District at Lockington indicates the sophisticated flood control infrastructure established in the wake of early 20th-century inundations.
