About this map

Sand Coulee Siphon dominates the hydrology of this arid Grant County landscape, illustrating the critical infrastructure required for mid-century agricultural development in Washington. The terrain is defined by the stark relief of the coulee systems, where water management is centralized through features like the siphon and nearby catchments. Small, isolated bodies of water such as Black Lake and Artesian Lake provide the only natural surface breaks in an otherwise channeled environment.
