The principal industries in the county today include agriculture, food processing, lumber, livestock, and recreation. The Columbia River also provides Morrow County with a number of related jobs. The Port of Morrow, situated on the Columbia River near the city of Boardman, was established in 1957.
Early cattlemen found an abundance of rye along the creek bottoms of the region and drove their herds into the area to forage on these natural pastures. Ranching was the primary economic force in the county for many years. Increased settlement, the enclosure of the free grazing lands and diminished pastures due to overgrazing, resulted in the decline of ranching during the 19th century, and farming became predominant. The completion of rail lines into the county in 1883 increased access to markets and encouraged wheat production in the area. The advent of technology for center pivot irrigation has been a further stimulus to the local economy.
Two natural gas-fired plants are located at the Port of Morrow; Coyote Springs I (255-276 MW), owned and operated by Portland General Electric; and Coyote Springs II (241-280 MW; PGE operator) owned by Avista Corp.
In 2022, it was reported that Amazon intends to build at least five commercial data centers in Morrow County. The company is reportedly pursuing a package of tax breaks to pursue construction of these centers, a project worth almost $12 billion total.[18]
