About this map

The Mississippi River and the Iowa River converge in this mid-century survey, revealing a complex landscape of islands, sloughs, and managed waterways along the state border. At the center of the river activity is Lock and Dam No.17, a critical infrastructure point near Otter Island. The town of New Boston sits on the eastern shore, overlooking Boston Bay and the interconnected wetlands of Sturgeon Bay and Mill Slough.

Rural life in the 1940s is anchored by localized landmarks such as Bay View Sch and Pin Oak Sch, while the floodplain is defined by an intricate network of drainage features like Prentiss Ditch and the Pumping Station. Large portions of the western bank remain marked as an Unsurveyed Area, contrasting with the detailed mapping of the intricate island systems, including Jonas Johnson Island and Half Moon Island.
