Mill Mapping Project

FOCRM entered into an agreement with the Department of Geospatial Studies at Northern Virginia Community College to produce a digital foundation of the topography and mill infrastructure of ports, roads, canals, waterways and mills comprising the flour manufacturing and export industry in the mid-1800s for the mid-Atlantic region of America. FOCRM members provided information that was mapped by the college.

The result of this project is an interactive map of 19th century mills which includes detailed information about a large number of these mills such as: various names, original building date, water source, whether it was a custom or merchant mill and specific location.

You can access this interactive map at to learn about mills in the mid-Atlantic region.

In addition there are two non-interactive maps: “19th Century Mill in the Potomac and Shenandoah Watersheds” and “The Mills of Fairfax County, Virginia Circa 1860.” Reduced versions of these maps are available at the Colvin Run Mill General Store.
