About this map

Lyman sits at the heart of an intricate irrigation network in the Nebraska panhandle, where the high plains transition into the North Platte River valley. This landscape is defined by the legacy of western movement and agricultural engineering, featuring the Emigrant Trail cutting across the northern reaches near Henry. The map illustrates a complex hydraulic system necessary for farming this arid region, including the Farmers Canal, Gering-Mitchell Canal, and numerous laterals like the Springer Main Lateral.

South of the settlement, the terrain rises toward Table Mountain and Rattlesnake Hill, overlooking water bodies such as Packer Lake and Little Moon Lake. A designated Historical Site near the North Platte River and the presence of gaging stations and siphons highlight the area's long-standing reliance on managed water resources. The boundary between Wyoming and Nebraska runs vertically through the sheet, marking a geopolitical divide in a region otherwise unified by its river-driven economy.
