Gilliam County is a county located in the U.S. state of Oregon. The county was established in 1885 and is named for Cornelius Gilliam, who commanded the forces of the provisional government of Oregon after the Whitman Massacre. In 2010, the population was 1,871. The seat of the county is Condon.



For untold generations, American Indians traversed the county on well-worn trails to reach fishing, hunting, foraging, and trading areas; but had claimed no tribal lands. Many of these trails are still visible in the rangeland. The first non-native people in the area were Americans following the Oregon Trail to the Willamette Valley. In the late 19th century, settlers arrived from the midwestern and eastern United States and Europe to stay and build farms and communities. Many settlers were also part of a larger reverse migration of people who had originally settled in the Willamette Valley.

The Legislative Assembly created Gilliam County on February 25, 1885, from the eastern third of Wasco County after residents complained that they were too far from the county seat in The Dalles. The first county seat was at Alkali, now Arlington. The question of a permanent county seat was placed on general election ballots in 1886, 1888, and again in 1890, when voters chose to move the county seat to Condon, known to early settlers as "Summit Springs." Once the question of the location of the county seat was settled, voters in Gilliam County proved reluctant to provide a courthouse in Condon. The county government operated out of a two-room house until 1903, when the county court appropriated money to construct a courthouse. This courthouse burned down in 1954 and was replaced the following year with the current courthouse.


Gilliam County is in the heart of the Columbia River Plateau wheat-growing region. The economy is based on agriculture, and wheat, barley and beef cattle are the principal products. Properties are large, with an average farm size of about 4,200 acres (17 km2).

The largest individual employers in the county are two subsidiaries of Waste Management Inc., Chemical Waste Management of the Northwest and Oregon Waste Systems, Inc., who run two regional waste disposal landfills. By levying a fee of $1 a ton, Gilliam County receives enough money to pay the first $500 of the property tax bills of its inhabitants, an amount that covers the full tax bill for almost half of the county inhabitants, as well as funding other county projects.

Hunting, fishing and tourism are secondary industries. Transportation also contributes to the local economy; two major rivers, the John Day and Columbia, cross the area east-to-west, as does Interstate 84. Oregon Route 19 connects the county's major cities north-to-south and provides access to the John Day Valley.



Though Gilliam County is located in central Oregon, politically it falls in line with the eastern side of the state. The majority of registered voters who are part of a political party in Gilliam County, as well as most counties in eastern Oregon, are members of the Republican Party.[1] In the 2008 presidential election, 58.36% of Gilliam County voters voted for Republican John McCain, while 38.74% voted for Democrat Barack Obama and 2.88% of voters either voted for a Third Party candidate or wrote in a candidate.[citation needed] These numbers show a small but clear shift towards the Democratic candidate when compared to the 2004 presidential election, in which 66.3% of Gilliam Country voters voted for George W. Bush, while 32.5% voted for John Kerry, and 1.2% of voters either voted for a Third Party candidate or wrote in a candidate.[2]
