1970 Map of Jeffrey Reservoir

USGS Topo · Published 1973

About this map

Jeffrey Reservoir dominates the center of this Lincoln County landscape, showing the integration of mid-century hydroelectric and irrigation infrastructure into the natural drainages south of the Platte River. The Tri-County Supply Canal feeds the reservoir, which sits at the head of several deep incisions in the loess hills, including Jeffrey Canyon and Conroy Canyon. This network was developed as part of the Department of the Interior program for the Missouri River Basin, indicated by the presence of a Powerplant and Substation at the reservoir's northern edge. To the north, the Platte River flows past Brady Island and Chester Island, where a Gaging Station monitors the river's discharge. The surrounding terrain is marked by intricate erosional features like Cottonwood Canyon and Snell Canyon, illustrating the complex topography of the Nebraska plains before it transitions into more open rangeland or agricultural fields.
