North Powder serves as the focal point of this 2014 survey, situated where the Clover Creek Valley and North Powder Valley converge. This High Desert landscape is defined by its sophisticated water management network, reflecting a long history of agricultural adaptation. A dense system of irrigation features, including the Sunnyslope Ditch, Moody Ditch, and Tavillion-Koester Ditch, crisscrosses the terrain to divert water from the North Powder River and Wolf Cr. The town grid is clearly delineated, showing a classic railroad-influenced layout along the La Grande-Baker Hwy.
