Wallowa River and its complex network of irrigation channels define the agricultural character of this Wallowa County landscape. The map reveals an intricate system of water management including Farmers Ditch, Granger Ditch, Big Bend Ditch, and the Wrenn Dobbin Ditch, which redirect water across the valley floor. These human-made features intersect with natural drainages like Swamp Cr and Prairie Cr, illustrating a long-standing reliance on water engineering to sustain the local ranching and farming economy.
