Walkerton serves as the primary hub of activity in this 2016 survey, where the borders of St. Joseph, Marshall, and Starke counties meet. The landscape is defined by an intricate network of agricultural drainage systems, including the Angeline Lemert Ditch, Lawrence Pontius Ditch, and Jesse McKesson Ditch, which channel water through the flat terrain toward larger bodies like Koontz Lake. This highly managed water system underscores the region's reliance on productive farmland and careful hydrology.
