2020 Map of Anderson Reservoir

About this map

Anderson Reservoir serves as a focal point for water management in this high-desert region of Malheur County. The map details an intricate system of ranching and irrigation infrastructure, including the Anderson Ditch and Crutcher Ditch, which divert water from local drainages to support agricultural efforts. The landscape is defined by its drainage networks, with Rattlesnake Cr, Crooked Cr, and Drought Cr cutting through the terrain between the Black Hills and Red Hills. Transportation in this era relied on a sparse network of ranch roads such as Gilbert Ranch Rd and the historical alignment of the Old Ion Hwy. This survey illustrates the ongoing importance of water rights and remote access in the vast basin-and-range country of southeastern Oregon.
