About this map

The settlement of Harper serves as the focal point for this landscape in Malheur County, situated where the Malheur River meets a network of vital irrigation infrastructure. The local agricultural economy is traced through the Harper Southside Canal and the Little Valley Lateral, which carry water across the high desert terrain to support ranching operations like the Cottonwood Creek Ranch Airport. This 2017 survey details a complex system of water management in an arid environment, including several namesake impoundments such as Stacey Reservoir Number Three and Stacey Reservoir Number Four.

Beyond the river valley, the terrain rises into distinct landforms such as Racehorse Flat and the expansive Harper Basin. The map records numerous water sources essential for livestock and wildlife, including Callahan Spring, Winter Spring, and Hunter Spring. Significant topographical landmarks like Hoodoo Ridge and High Point overlook the drainage basins of Cottonwood Cr and Basin Cr, illustrating the relationship between the area's sharp elevation changes and its seasonal waterways.
