About this map

Harper Basin and the surrounding high ridges of Malheur County define this high-desert landscape in eastern Oregon. Water management is the primary human imprint on the terrain, evidenced by a complex network of catchment systems including Slim and Fatty Reservoir, Quick Fill Reservoir, and the Stacey Reservoir Number One. These features, alongside numerous springs like Refuge Spring and Quicksand Spring, illustrate the critical importance of water resources for ranching and land use in this arid environment.

Elevations reach significant heights at Freezeout Mtn and Sourdough Mtn, providing a stark contrast to the low-lying Sand Hollow and Box Canyon. Transport is limited to the lonely stretch of Freezeout Lake Rd, which connects the basin to the higher elevations of Keeney Ridge. This 2020 survey provides a modern accounting of the natural topography and the specialized reservoirs required to sustain life and industry in the region.
