2017 Map of Coulee City

About this map

Coulee City sits at the northern edge of a landscape defined by the Channeled Scablands, where the prehistoric Dry Falls and the carved Upper Grand Coulee meet. This 2017 study illustrates the modern water management system and recreational infrastructure that dominates the terrain, including the southern reaches of Banks Lake and the Bacon Tunnel. The topography is exceptionally detailed, showing the basalt formations and coulees such as Trail Lake Coulee and Hudson Coulee. Scattered settlements like Odair and Bacon are documented alongside natural landmarks including Umatilla Rock and Table Rock. The map also captures the local transportation network, from the Coulee City Airport to the system of county roads including Pinto Ridge Rd NE, providing a clear view of how irrigation and geology have shaped this Grant County corridor.
