1979 Map of Harrison SW

About this map

The Niobrara River carves a winding path across this portion of Sioux County, defining the drainage patterns and physical character of the High Plains landscape. The river's influence is evident in the presence of the Lakatoh Ditch, an irrigation feature that speaks to the agricultural management of the region's semi-arid environment. Compiled from aerial photography taken in 1973 and field-checked by the U.S. Geological Survey in 1974, this map provides a precise record of water resources and ranch-land infrastructure during the late twentieth century. Beyond the main river channel, the terrain is marked by isolated landmarks such as a specific Drill Hole and several rural wells, reflecting the local reliance on groundwater and the ongoing exploration of the area's geological potential.
