Morrow County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 12,186. ^[1] The county seat is Heppner. ^[2] The county is named for one of its first settlers, Jackson L. Morrow, who was a member of the state legislature when the county was created. Half of the Umatilla Chemical Depot, which includes the Umatilla Chemical Agent Disposal Facility, and the Naval Weapons Systems Training Facility Boardman are located within the county. Morrow County is part of the Pendleton-Hermiston, OR, Micropolitan Statistical Area. It is located on the south side of the Columbia River and is included in the eight-county definition of Eastern Oregon.

History

Morrow County was created in 1885 from the western portion of Umatilla County and a small portion of eastern Wasco County. ^[3] It is named for Jackson L. Morrow, a state representative who advocated for the county's formation. Heppner was designated the temporary county seat at the time the county was created and narrowly defeated Lexington in the election held in 1887 to determine the permanent county seat.

Economy

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. ^[27]
