1972 Map of German Valley

About this map

Union Slough dominates this northern Iowa landscape, a vast wetland corridor that had been partially reclaimed and managed by the early 1970s. The area is characterized by an extensive network of water management features, including Drainage Ditch No 90 and Storks Ditch, which crisscross the agricultural townships of Ledyard, Lincoln, and German. This intersection of conservation and farming is evident in the presence of the Schwob Marsh State Game Management Area and the Gabrielson Wildlife National Refuge, protecting local habitats like Dismal Swamp and Pierce Pool.
