2017 Map of Tekamah NW

About this map

Decatur sits prominently on the western bluffs where the river plain transitions into higher ground, overlooking the complex oxbows and drainage systems of the Missouri River valley. This 2017 survey reveals the intricate hydrography along the Nebraska-Iowa state line, including the substantial Lake Quinnebaugh and the engineered channels of Wuchoff Ditch and Riverside Ditch. The map illustrates the shifting nature of the river's path, preserved in named meanders such as Lower Decatur Bend, Upper Louisville Bend, and Lower Blencoe Bend.
