History

The Oregon 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 their county seat in The Dalles. The first Gilliam 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.

The Shepherds Flat Wind Farm, an 845 megawatt (MW) wind farm, began construction near Arlington in 2009, shortly after approval by state regulators. The wind farm was being built by Caithness Energy using General Electric (GE) 2.5 MW wind turbines, and it will supply electricity to Southern California Edison. In April 2011, Google announced they had invested $100 million in the project. The wind farm was estimated to have an economic impact of $16 million annually for Oregon.

Economy

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.
