Morrow County is a county in the U.S. state of Oregon. As of the 2010 census, the population was 11,173.[1] The county seat is Heppner.[2] The county is named for one of its first white 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, is within the county.

Morrow County is part of the PendletonHermiston, 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.


Morrow County was created in 1885 from the western portion of Umatilla County and a small portion of eastern Wasco County.[3] 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.


According to the U.S. Census Bureau, the county has a total area of 2,049 square miles (5,310 km2), of which 2,032 square miles (5,260 km2) is land and 17 square miles (44 km2) (0.8%) is water.[4]

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.

The Port of Morrow, situated on the Columbia River near the city of Boardman, was established in 1957.

The coal-fired electricity generation plant, the Boardman Turbine Coal Plant (601 megawatts), is 14 miles (23 km) southwest of the town of Boardman and is owned by Portland General Electric (PGE; 66%-owned and operated), Idaho Power (10%), Pacific Northwest Generating (10%), and General Electric Credit Corp. (16%). There are also two natural gas-fired plants 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.
