About this map

Harlan County Lake dominates the upper landscape of this 1974 survey, showing the reservoir at an elevation of 1946 feet. The Republican River enters the map from the west, feeding into the lake near the settlement of Orleans. The northern shoreline is shaped by several distinct water bodies, including Sappa Creek, Flag Creek, and Rope Creek, which intersect with the transport corridor of the Burlington Northern railroad.

South of the reservoir, the topography transitions into a network of drainages and valleys, where Prairie Dog Creek and Spring Brook flow across the Nebraska Kansas state line. The map records the infrastructure of the era, from the Sewage Disposal Ponds near Orleans to a network of siphons and a discontinued railroad grade near Alma. This survey captures the region after the establishment of the dam, showing the intersection of vital water resources and the agricultural borderlands between Harlan County and Phillips County.
