1979 Map of Cowan Reservoir

USGS Topo · Published 1979

About this map

The Diamond A Desert defines this high-desert landscape along the Idaho and Nevada border in the late 1970s. This survey records a remote ranching environment where water management is the primary driver of human activity, centered around the Cowan Reservoir and the extensive Cowan Ditch system. Evidence of early settlement and livestock operations appear at the Cowan Homestead, Rutherford Ranch, and Jones Ranch, while isolated features like a simple Shack and a Water Tank suggest the sparse infrastructure of the era.
