Woodburn and Edgerton anchor this 2013 survey of the Indiana-Ohio borderlands, where the landscape is defined by a dense network of engineered drainage that has transformed the local hydrology. The prevalence of named ditches, such as Edgerton-Carson Ditch and Litzenberg Ditch, indicates the intensity of agricultural land management required in this region. These man-made channels intersect natural waterways like Flatrock Cr and Hoffman Cr, illustrating the complex relationship between regional development and the natural water table.
