About this map

The agricultural and hydraulic infrastructure of central Oregon takes center stage in this 1962 survey. The settlement of Plainview serves as a local hub, supported by community landmarks such as the Plainview Sch and a Grange Hall. The map illustrates a landscape shaped by water management, featuring a complex network of irrigation that includes the Plainview Ditch, the Columbia Southern Canal, and the Tyler Road Canal.

To the south, the engineering of the Tumalo Dam and the Upper Tumalo Reservoir dominates the terrain near Bull Flat. The Deschutes National Forest Boundary marks the western edge of the quadrangle, where the open plains give way to the wooded rises of the national forest. The topography reveals the stark transition between the seasonal flow of Blakely Creek and the arid depths of Dry Canyon, reflecting the region's reliance on the flumes and canals that sustain local farming.
