2014 Map of Priest Rapids NE

About this map

Mattawa sits at the northwestern edge of this 2014 survey, anchoring an area dominated by the agricultural development of the Wahluke Slope. The landscape is defined by a rigorous grid of section roads and the complex irrigation infrastructure necessary for farming this arid region, including the Mattawa Drain and the Saddle Mountain Wasteway. To the south, the Columbia River carves a deep boundary between Grant and Benton counties, featuring the distinctive China Bar along its northern bank. This map illustrates the intersection of modern transit and land use, from the Wa-243 corridor to local identifiers like the Christensen Bros Wahluke Strip, reflecting the 21st-century character of central Washington's Columbia Basin.
