About this map

Harney Lake and the wetlands of the Warm Springs Valley dominate this high-desert landscape in central Oregon. The map illustrates a complex water management system designed for the arid environment, featuring the Saint-clair Canal and Goulden Canal, which redirect flows from Silver Cr into the basin. These man-made channels reflect the region's long history of ranching and irrigation in the shadow of local heights like Freeman Butte.

A network of rural routes, including the OO Ranch Rd, Double O Ranch Rd, and Silver Sage Ranch Rd, connects the disparate parts of this ranchland. To the north, the terrain transitions into the more dramatic relief of Brown Canyon and the depression of Sand Hollow, while the Beshell Grade provides a path through the higher elevations. The interplay of terminal lake beds and irrigation engineering is the defining characteristic of this Harney County landscape.
