2011 Map of Southwest Harney Lake

About this map

Harney Lake dominates the upper-right quadrant of this high-desert landscape in Harney County, characterized by a complex network of seasonal water sources and named flats. The presence of Moon Ranch in the northwest, situated near Warm Springs Valley, suggests a long-standing reliance on the scattered springs such as Upper Sizemore Spring and Lower Sizemore Spring for livestock and survival in this arid environment. Southward, the terrain transitions into broad basins like Basque Flat, where water management is evident through features like the Basco Spring Reservoir and the Weed Lake Butte/Waterhole. Transportation is limited to a few arterial routes, notably S Harney Rd, which skirts the southern edge of the lake bed, connecting the various flats and remote springs across this sparsely populated region of Oregon.
