2011 Map of Rock Island Dam
USGS Topo · Published 2011About this map
The Columbia River dominates this portion of Central Washington, serving as the defining border between the high coulees and the complex canyon systems to the west. This landscape is anchored by the Rock Island Dam, where the settlement of Voltage sits along the river's edge. The terrain is deeply incised by ancient geological forces, evidenced by the broad Moses Coulee and the winding course of Douglas Creek.
