2020 Map of Malheur Lake West

About this map

Voltage serves as a lone settlement marker in this high desert wetland system where the Donner und Blitzen River and West Fork Silvies River empty into the expansive basin of Malheur Lake. The landscape is defined by the hydrologic shifts of the Blitzen Valley, where man-made features like Bull Ditch intersect with natural water sources such as Sodhouse Spring and Indian Spring. This 2020 survey illustrates the remote character of the Harney Basin, highlighting the isolation of named landforms like Graves Island and Cole Island within the marshy lakebed. The map also traces the foundational road network of the region, including Narrows-Princeton Rd and Center Patrol Rd, which provide essential access through the seasonal wetlands and alkali flats that characterize this part of southeastern Oregon.
