About this map

Garland Lake sits at the heart of this high-desert landscape in Grant County, Washington, where the terrain is defined by the unique Coulee formations of the Columbia Plateau. The land is carved by natural features such as Arbuckle Draw in the northeast corner, reflecting the erosive forces that shaped this region. A strictly organized grid of rural corridors, including Rd 36 Ne and Rd 30 Ne, segments the landscape for agricultural use, connecting isolated farmsteads across the township lines. Aviation infrastructure is represented by the Coulee City Airport, which occupies a flat bench of land in the northwest. This 2017 survey illustrates the modern intersection of heavy topographic relief and the precise, human-imposed geometry of the Public Land Survey System, which remains the primary framework for land ownership and navigation in this part of eastern Washington.
