1971 Map of Elwood NW

About this map

Gallagher Canyon State Recreation Area and the intricate engineering of the Tri County Supply Canal define this Nebraska landscape during the early 1970s. This survey, conducted for the Department of the Interior's Missouri River Basin development program, shows a region heavily shaped by water management and transit. The Burlington Northern railroad cuts through the southern portion of the quadrangle, running parallel to the winding course of Plum Creek. Significant water bodies like Gallagher Canyon Lake and the northern tip of Johnson Lake illustrate the area's dual role as a utility corridor and a recreational hub. Further south, the Elwood Reservoir sits amidst the deeply eroded terrain of Plum Creek Canyon, demonstrating how local topography was leveraged for large-scale water storage and land management.
