The Missouri River forms the defining boundary of this landscape along the Nebraska-Iowa border in 2011, characterized by its dramatic sweeping curves and engineered water management systems. Distinctive river features like Lower Decatur Bend, Upper Louisville Bend, and Lower Blencoe Bend illustrate the meandering nature of the waterway. The interior agricultural land is partitioned by a rigid grid of county roads such as Co Road V and Co Road Tu, which are punctuated by irrigation and drainage infrastructure including Wychoff Ditch and Riverside Ditch. This era of the Missouri River valley shows a highly managed flood plain where the wild path of the river is bordered by established residential and service corridors like S Riverview Dr and 3rd Ave near the community of Decatur.
