About this map

Big Sage Reservoir dominates this high-plateau landscape in northern California, where complex water management defines the local geography. Numerous smaller catchments such as Upper Cummings Reservoir, Lower Cummings Reservoir, and Kelley Reservoir are scattered across the terrain, connected by seasonal drainage systems like W Rock Cr and Noble Cr. The presence of Devils Garden Airport and the Big Sage Campground suggests a region oriented toward backcountry utility and seasonal recreation.

Local landmarks like Porcupine Rim and Salisbury Gulch provide topographical context for the network of forest and ranch roads. The map reveals the infrastructure of the area through routes such as Triangle Ranch Rd and Crowder Flat Rd, which link isolated springs like Mill Spring and Rock Spring. This data provides a detailed look at the hydrology and access points within this portion of Modoc County.
