About this map

Jackson Creek Ranch sits at the heart of this high-desert landscape in Malheur County, where water management is the primary driver of human settlement and activity. The terrain is defined by a complex network of canyons and peaks, including the prominent High Peak and the distinctive Sugarloaf. To support ranching in this arid environment, numerous water features are mapped, ranging from the Jackson Summit Reservoir to the aptly named Hole-in-the-Ground Reservoir.

The hydrology of the area flows through several major drainages, including Tenmile Creek, Cottonwood Creek, and the various forks of Jackson Creek. Isolated water sources like Potato Water Spring and Chicken Springs provided critical stopovers for livestock and travelers. This 1982 provisional survey captures the rugged infrastructure of the Oregon high country, including the scattered reservoirs and springs that sustained the local ranching economy.
