1983 Map of Coulee Dam

About this map

Grand Coulee Dam anchors this landscape, holding the vast waters of Lake Roosevelt as it winds through the deep canyons of the Columbia River. The map captures the complex geography of north-central Washington in the early 1980s, where the river serves as a natural boundary for the Colville Indian Reservation and the Spokane Indian Reservation. South of the water, the terrain transitions into the high plains of Lincoln County, defined by the steady transit of the Burlington Northern railroad connecting agricultural hubs like Davenport and Wilbur. This 1983 revision offers a detailed look at the infrastructure of the Coulee Dam National Recreation Area and the rugged topography of the Swawilla Basin. Notable peaks such as Mica Mtn and Johnny George Mtn rise above the river breaks, while the intricate system of coulees and creeks, including Wilson Creek and Crab Creek, reveals the ancient volcanic drainage patterns of the region.
