About this map

The Lower Powder Valley serves as a primary geographical focus of this 2017 survey, where the Powder River meanders through a landscape defined by an intricate network of irrigation and water management features. This rural corridor near the Union Co Baker Co line reveals a reliance on engineered water transport, with the Kennedy Ditch, Emele Ditch, Big Cr Ditch, and Erwin Ditch all drawing from the local watershed to support the valley's land use.

Infrastructure in this part of eastern Oregon is largely centered on ranching and residential heritage, anchored by landmarks like Miles Bridge and the Big Creek Cem. Higher elevations along the Blue Mountain Ridge Rd overlook significant water storage at Wirth Reservoir and Homesite Reservoir. Named drainage systems, including Little Rattlesnake Cr and Big Creek, carve through the terrain, illustrating the natural flow patterns that dictated the placement of historic routes such as Miles Bridge Rd and Fred Bowman Rd.
