Irrigon stands as a central hub on the southern banks of the Columbia River in this early 1960s survey. The landscape is defined by the massive expansion of Lake Umatilla following the construction of downriver dams, which submerged portions of the original shoreline and relocated earlier infrastructure. Transportation is a primary theme of the sheet, with the Union Pacific and Burlington Northern railroads paralleling the water, while the West Extension Canal winds through the southern fields to support local agriculture. Regional heritage is preserved through landmarks like the Houghton Sch and a local Cem, while the John Day Wildlife Management Area occupies the river's northern banks. The inclusion of the Compressor Station and various pipelines highlights the industrial energy corridor developing along the river during this era.
