2015 Map of Hahnaman

About this map

Hahnaman sits at the southern edge of a landscape defined by an extensive system of agricultural drainage in Whiteside County. This 2015 survey reveals the engineered hydrology of the region, where the natural flows of Coon Cr and Spring Slough are supplemented by an intricate network of man-made channels including the Main Ditch, Winnebago Ditch, and S Fork Ditch. These waterways reflect the historical effort to reclaim the prairie for productive farming. Aviation history is also present through the Whiteside County Airport-Jos H Bittorf Field at the northern boundary and the smaller Cady Aerial RLA Airport further south. Local genealogy and land use are anchored by the Golder Cem and a grid of family-named roads such as Gaulrapp Rd and Grennen Rd, tracing the boundaries between Whiteside and Lee counties.
