2021 Map of Harmon
USGS Topo · Published 2021About this map
Harmon serves as the central hub of this agricultural landscape in Lee County, where the transition from natural waterways to engineered drainage is clearly visible. The southern portion of the quadrangle is defined by the Green River and Walnut Cr, while the more developed northern sections rely on systems like the Winnebago Ditch and Main Ditch to manage the low-lying prairie terrain. These water management features are integral to the region's farming history and are interspersed with historical markers such as Greenwood Cem and Holy Cross Cem.
