About this map

Tumalo Dam and the Upper Tumalo Reservoir stand as central water management features in this High Desert landscape west of the Deschutes River. The map documents a complex network of irrigation infrastructure essential to the region's agricultural history, including the Plainview Ditch, Maxwell Ditch, and the Columbia Southern Canal. These man-made watercourses trace the contours of the land, navigating through natural features like Bull Flat and the deep incision of Dry Canyon.

Residential development appears in clusters such as Ponderosa Cascade and Cascade Estates, while the eastern portion of the Deschutes National Forest borders the western edge of the survey. The presence of the Sage Ranch Airport and the diagonal path of Us-20 highlight the area's role as a transportation corridor connecting regional hubs. This survey provides a precise look at the intersection of forest lands, rural ranching, and the critical water systems that sustain them.
