Waterman and the nearby locales of Wayland and Duroc anchor this portion of Umatilla County, defined by a sophisticated system of high-country water management. The landscape is etched by essential irrigation infrastructure, including the White Ditch and the curiously named Love Loney Ditch, which redirect flow from natural drainages like Swartz Creek and Pine Creek. These systems support the agricultural viability of the region, feeding into the White Reservoir in the northwest corner.
