The Port of Mattawa is a small port authority based in Mattawa, Washington, situated in southern Grant County along the Columbia River. It functions as an inland port serving central and eastern Washington and sits within reach of the Ports of Seattle and Tacoma. The port provides sites for agribusiness-related facilities, including wineries, food processors, fresh produce packing operations, cold storage, and small manufacturing, leveraging its central location near major irrigated production areas such as the Columbia Basin and the Yakima Valley. Access to Interstate 90 and comparatively low electricity costs from Grant County PUD are notable advantages of its location. The Mattawa area is a growing rural community with about 10,000 residents, and nearby central Washington communities form MSAs with a combined population nearing one million. As a government-administered entity, the Port of Mattawa supports agribusiness and related industries by providing suitable sites for production, processing, and storage facilities.
