2024 Map of Hat Rock

About this map

Lake Wallula dominates the center of this landscape, marking the interstate boundary between Oregon and Washington where the Columbia River flows through the high desert. On the northern shore, the small settlement of Berrian sits beneath the steep walls of Rush Canyon, while the southern bank in Umatilla County features the riverside community of River View. The map captures a sophisticated irrigation and drainage network essential to this arid region, including the T Canal, Hat Rock Drain, and Cold Springs Drain.
