About this map

The Missouri River carves a wide alluvial path through this 1986 survey, defining the border between Nebraska and Iowa. The landscape is dominated by the expansive Winnebago Indian Reservation and Omaha Indian Reservation to the west, where the hilly terrain meets the fertile bottomlands. These ancestral lands are anchored by settlements like Winnebago and Macy, surrounded by an intricate network of drainage including Blackbird Creek and Logan Creek.

To the east, the Iowa side of the valley features linear drainage patterns and oxbow remnants like Browns Lake and Blue Lake, preserved within dedicated conservation areas such as Lewis and Clark State Park. The region's transport history is visible in the divergent paths of the Burlington Northern and Chicago and North Western railroads, which connected the agricultural hubs of Pender, Bancroft, and Sloan to the industrial centers of Sioux City and South Sioux City at the northern confluence.
