Columbia Agricultural Airport

The closure was most likely due to economic reasons and land use changes. As a private agricultural strip, its existence was tied to the needs of local farm operations. Potential reasons include the consolidation of agricultural aviation services at the larger and better-equipped Tri-Cities Airport (KPSC) just a few miles southeast, the sale of the property, or the owner no longer having a need for a private airstrip. There is no evidence to suggest it was closed due to a specific accident or for military conversion.

The site of the former airport has been reclaimed for agricultural use. The faint, ghostly outlines of the two former runways, arranged in an 'X' pattern, are still visible in satellite imagery. However, they are being actively farmed over and are integrated into the surrounding irrigated crop circles. There are no remaining hangars, fuel pumps, or any other aviation-related infrastructure on the site.

Columbia Agricultural Airport was a privately owned airfield whose primary purpose was supporting the vast agricultural industry of the Columbia Basin. Its operations were centered on agricultural aviation, commonly known as crop dusting or aerial application. Aircraft, likely models such as the Air Tractor, Grumman Ag-Cat, or similar types, would have used the two dirt/gravel runways to apply fertilizers, pesticides, and other treatments to the surrounding fields of potatoes, onions, wheat, and other crops. Its significance was purely local, serving as a vital, specialized tool for the region's farmers.

There are no known plans or prospects for reopening the Columbia Agricultural Airport. The land is now productive farmland, and its aviation functions have been fully absorbed by other regional airports. Given its proximity to the major Tri-Cities Airport (KPSC), which has extensive facilities for general and commercial aviation, there is no practical or economic incentive to re-establish this small, private field.
