2011 Map of Jeffrey Reservoir

About this map

Jeffrey Reservoir dominates this portion of Lincoln County, serving as a critical node in the regional water management system of the early 21st century. Fed by the Tri-County Supply Canal, the reservoir is defined by its irregular, finger-like shoreline and several engineering landmarks, including the Earth Dam-Canal Mile 228 Dam. The surrounding landscape is a complex of canyons and Platte River bottomlands, where the Platte River itself flows past Chester Island in the north. The area's history is etched into its road names, with routes like S Fort McPherson Rd and E Fort McPherson Rd referencing the region's 19th-century military heritage. Deep drainages such as Snell Canyon and Conroy Canyon cut through the uplands, illustrating the contrast between the engineered water systems and the natural Nebraska topography.
