2023 Map of Anderson Reservoir

About this map

Anderson Reservoir serves as a central hydrological landmark in this high-desert portion of Malheur County, where the management of water defines the land use. The map illustrates a network of engineered irrigation, including Anderson Ditch and Crutcher Ditch, which redirect flow across a landscape shaped by seasonal drainages like Rattlesnake Creek and Crooked Creek. This reliance on water infrastructure suggests the long-standing importance of ranching and livestock in the region, evidenced by access routes such as Gilbert Ranch Rd. To the south, the terrain rises toward the Black Hills and Red Hills, while the presence of the Old Ion Hwy provides a historical trace of earlier transportation corridors through this part of the Oregon desert.
