About this map

High desert irrigation and ranching infrastructure define this section of Deschutes County, where the Columbia Southern Canal and Tumalo Feed Canal represent a legacy of water management essential to the region's development. The landscape is marked by the wide expanse of Bull Flat and the intricate hydrology of the Plainview Ditch and Snow Creek Ditch. These man-made waterways contrast with the natural depression of Dry Canyon, illustrating the effort required to cultivate this arid terrain.

Within the Deschutes National Forest, the topography shifts toward more wooded and varied elevations. Aviation and recreation also shape the local geography, visible through the Sage Ranch Airport and a network of pathways like the Fryrear Canyon Trl and Cline Buttes T-11 Trl. The Upper Tumalo Reservoir serves as a focal point for both water storage and the surrounding network of local roads such as Sage Ranch Rd and Innes Market Rd.
