1963 Map of Dorris Reservoir

About this map

The Modoc National Wildlife Refuge dominates the northwestern portion of this landscape, centered on the expansive Dorris Reservoir. This high-desert terrain in Modoc County is defined by its complex water management systems, including an extensive network of creeks and man-made impoundments. To the south and east, specialized water infrastructure such as the Old Powerhouse and Porter Reservoir suggest the historical development of ranching and utility systems during the mid-20th century.
