Horicon Marsh dominates the western edge of this Dodge County landscape, where the vast wetlands are crisscrossed by drainage infrastructure like Townline Ditch and Clarks Ditch. The eastern half of the quadrangle transitions into a structured agricultural and industrial grid, anchored by the city of Mayville and its associated waterworks at the Lower Mayville Millpond 174. This millpond and the East Branch Rock River signify the long-standing water-driven economy of the region.
