2020 Map of Jonesboro

About this map

The Malheur River cuts a distinct horizontal path through this high desert terrain in Malheur County, providing the primary water source for local ranching and agriculture. The reliance on water management is evident in the Jonesboro Canal, which diverts flow along the river valley, and various upland water sources like Peavine Reservoir and Bristol Reservoir. The landscape is defined by its numerous drainages and springs, including Big Swamp Cr and Dipping Vat Cr, suggesting a history of livestock grazing and range management. High points like Stemler Ridge and the Stemler Basin overlook complex geological features such as Currey Canyon and Chalk Gulch. Seasonal hydrology is marked by named springs like Buckboard Spring and Saddlehorse Spring, which served as critical landmarks in an area dominated by open range and limited road access via Pole Creek Rd.
