2011 Map of Grand Coulee Dam

About this map

The monumental infrastructure of the Grand Coulee Dam anchors this 2011 survey, showing the complex interplay between the Columbia River and the massive reservoir of Franklin D Roosevelt Lake. The map details the clusters of development that grew around the dam's construction and operation, including the incorporated communities of Grand Coulee, Coulee Dam, and Elmer City. Portions of the Colville Indian Reservation appear in the northern section, while the southern landscape is defined by the unique geology of Rattlesnake Canyon and Spring Canyon. Local landmarks like the Coulee Dam Seaplane Base and the Grand Coulee Grange highlight the area's specialized transportation and community hubs. The cartography also traces the canyon roads and vistas, such as Crown Point Vista, which provide vantage points over the harnessed river valley.
