The Powder River carves a deep path through this section of eastern Oregon, where the high-desert terrain is marked by an extensive network of irrigation infrastructure. This landscape, situated along the Union Co and Baker County line, reveals the complex water management required for ranching and agriculture in the Lower Powder Valley. Significant waterworks such as the Kennedy Ditch, Emele Ditch, and Basche Ditch contour the hillsides, feeding from natural sources like Big Cr and Little Rattlesnake Cr.
