About this map

Blue Lake and the meandering path of the Missouri River dominate this landscape along the Iowa-Nebraska border. The map illustrates a complex hydrologic network of drainage channels, including the McCandless Cleghorn Ditch, Murphy Ditch, and Myrland Ditch, which were engineered to manage the fertile bottomlands of the Missouri Valley. To the west, the river creates distinct landforms such as Tieville Bend and Middle Decatur Bend, marking the shifting boundary between Monona County and Burt County.

Small settlements like Whiting and the western edge of Onawa provide local context, connected by a grid of rural roads and highways such as Co Hwy K45. For those researching family history or local landmarks, Harrison Cem is located near the northern edge, while B-B Farms Airport sits among the agricultural tracts. This 2015 survey reflects a region defined by its relationship with the river, from the wetlands near Wood Cr to the structured farmland that fills the floodplains.
