Port of Mattawa Our mission is to assist those businesses looking to grow in the Northwest and contribute to the region's economic growth.

The purpose of the Port of Mattawa is to attract new business, enhance infrastructure, and promote economic growth and development in the south Grant County area. The Port of Mattawa is located in south Grant County on the Columbia River in Washington State and is the closest inland port in central/eastern Washington State to the Ports of Seattle and Tacoma. Grant County is the top agricultural production county in Washington State, and Mattawa is major producer of wine grapes, apples, cherries, potatoes and onions and other high-value irrigated crops. The Port offers ideal sites for wineries, food processors, fresh produce packing companies, cold storage facilities, small manufacturers, and is a prime location for agribusiness companies because of its central location in Washington State near major agricultural production areas including the Columbia Basin and the Yakima Valley. The Port of Mattawa is also very close to Interstate 90 and enjoys some of lowest-cost electricity in the United States, high-capacity commercial and industrial water and waste-water facilities, and broadband fiber-optic telecommunications.
