About this map

South Mountain anchors the high desert landscape of Malheur County, where the southern flow of the Malheur River cuts through the bottom of the quadrangle. This 2017 survey reflects a remote ranching and grazing environment characterized by a sophisticated network of small-scale water management. Numerous basins and improved springs are distributed across the terrain, including the Hog Cr Reservoir Number Two, Alfred Reservoir, and Tub Springs Reservoir.

Landowners and local historians can trace the water rights and grazing infrastructure marked by named features like Boney Spring Number 1 and Rimrock Spring. The geography is defined by significant drainage systems such as China Creek and South Cottonwood Cr, which feed into the primary river valley. Isolated access is maintained through the Shelley Rd and Antelope Spring Rd corridors, serving the scattered reservoirs that sustain this arid region.
