About this map

The Saint Marys River meanders through the heart of Decatur, anchoring a landscape defined by an extensive network of managed waterways. This 2010 survey details the modern layout of the city and its surrounding rural townships, where dozens of drainage features like Koos Ditch, Borum Run, and Yellow Creek reveal the agricultural engineering required for this region. Local history is preserved at several burial grounds, including Greenwood Cemetery and Saint Josephs Cemetery, which sit alongside the urban center, while more remote sites like Alpha Cemetery and Union Chapel Cemetery mark the outskirts.

Industrial and civic landmarks are prominently featured, from Gage Airport to the Adams County Home. Beyond the main settlement, the smaller community of Monmouth sits to the north, and Elm Tree Crossroads serves as a waypoint in the southern agricultural flats. The map also documents local infrastructure such as the Saddle Lake Dam and the various county roads that lattice the territory between the river forks.
