About this map

The Saint Marys River winds through the heart of Decatur, anchoring a landscape defined by an intricate network of agricultural drainage and early 21st-century infrastructure. This 2013 survey captures the city's transition from its urban core to the rural townships of Adams County, where the grid of county roads meets smaller outlying settlements like Monmouth and Elm Tree Crossroads. The surrounding terrain is heavily marked by a systematic web of waterways such as Gerke Ditch, Koos Ditch, and Holthouse Ditch, illustrating the intensive land management required for the region's productive farmland.

Local landmarks of historical and civic importance appear throughout the quadrangle, including the Gage Airport and the Adams County Home located southeast of the city center. The map documents the modern footprint of Decatur, from the Industrial Park to residential developments like Crosse Pointe. Water features such as Saddle Lake and the confluence of Yellow Cr with various ditches reflect the natural hydrology that has influenced settlement patterns in this part of northeastern Indiana for generations.
