1970 Map of Heron Lake NE

About this map

Des Moines River waters wind through the southeastern corner of this Cottonwood County landscape, providing a natural contrast to the rigid grid of the surrounding prairie. This 1970s survey captures a transition in land use, where the draining of wetlands is evident in features like Berry Lakebed and the extensive network of drainage projects such as Judicial Ditch No 14 and Ditch No 2. Social life in the townships of Amo and Springfield centered on local institutions like Amo Ch, United Amo Ch, and the local Townhall. The glacial history of the region is written in the topography of Rose Hill and the scattered prairie potholes including Carey Lake, Long Lake, and Round Lake. Pockets of conservation are noted in the National Wildlife Management Area, preserving habitat amidst an agricultural terrain increasingly defined by geometric field lines and gravel extraction sites.
