USGS Topo · Published 1984About this map
The Columbia River corridor dominates this mid-1980s landscape, illustrating a complex network of hydroelectric power, military logistics, and irrigation-based agriculture. The presence of the McNary Dam and its adjacent Powerhouse transformed the river into Lake Wallula and Umatilla Lake, creating specialized environments like the Umatilla Wildlife Refuge. Significant land is dedicated to the Umatilla Ordnance Depot, a massive facility defined by its grid of bunkers and the specialized Ordnance Airstrip.
