2013 Map of Onawa

About this map

Onawa serves as the focal point of this Monona County landscape, showing a grid of residential and civic development north of the Onawa Municipal Airport. The map highlights the town's role as a local hub, featuring the Monona County Fairgrounds and the Kiwanis Museum Complex. Outside the town center, the landscape is defined by an extensive network of drainage infrastructure, including the Garretson Outlet Ditch, Losey Ditch, and Hackett Ditch, which manage the low-lying terrain surrounding the Little Sioux River. In the northeast corner, the small settlement of Kennebec sits near the river's meandering course. This 2013 survey illustrates the highly organized agricultural section lines and water management systems required to maintain the fertile plains of western Iowa, far from the Missouri River's edge but still dictated by its historical floodplain patterns.
