About this map

The East Fork Des Moines River meanders across this rural Kossuth County landscape, defining the local geography alongside several significant tributaries. To the north, Mud Cr and Prairie Cr drain the glacial plains, while Calamus Cr occupies the southern reaches of the township. The presence of Greenwood Marsh and the engineered Drainage Ditch Number 69 illustrates the complex relationship between the region's natural wetlands and the intensive agricultural development that has shaped northern Iowa. This survey documents the rigid section-line road grid, including Co Hwy A42, which segments the land into the productive farmsteads characteristic of the Prairie Pothole Region.
