2018 Map of Turkey River

About this map

The Mississippi River creates a complex landscape of islands and sloughs along the border of Iowa and Wisconsin, where the Turkey River meets the larger waterway. This 2018 survey documents the intricate geography of the riverbottoms, including Island Number One Hundred Ninety-two and Island 189, alongside several side channels like Skimmethom Slough and Cassville Iowa Slough. The land rises sharply from the floodplains into a series of deeply carved valleys such as Adams Mill Hollow and Hog Hollow. For those tracing local history, the map identifies several rural landmarks and family-named cemeteries including Bierer Cem, Redman Cem, and Goshen Cem. The small settlement of Millville sits at a strategic junction inland, while Cassville marks the riverfront edge, reflecting the enduring connection between these communities and the river navigation and valley farming that shaped the region.
