2017 Map of Anderson Reservoir

About this map

Anderson Reservoir serves as a central hydrological landmark in this arid portion of Malheur County, drawing from a complex network of seasonal watercourses and engineered irrigation. The landscape is defined by the management of water through the Anderson Ditch and Crutcher Ditch, which redirect flow across the high desert terrain. These systems are essential for the surrounding cattle ranching operations, evidenced by local thoroughfares such as Gilbert Ranch Rd. To the south, the topography rises into the Black Hills and Red Hills, while drainage is carved out by Crooked Cr and Rattlesnake Cr. The presence of the Old Ion Hwy in the southeast corner provides a historical connection to earlier regional transit routes through the Oregon interior, tracing a path alongside the intermittent creek beds and rugged township boundaries.
