Parr and Aix sit within a highly organized agricultural landscape in southern Jasper County, where the natural drainage of the Iroquois River has been extensively augmented by a network of man-made waterways. This 2019 survey reveals how the local economy is structured around these drainage systems, including Jungles Ditch, Rowan Ditch, and Brunner Ditch, which follow the township and section lines of the Public Land Survey System. These ditches are essential for managing the low-lying prairie land, allowing for the dense grid of county roads that connect the small settlements of the region.
