Umatilla County // is a county located in the U.S. state of Oregon. As of the 2010 census, the population was 75,889. The county seat is Pendleton, but the largest city is Hermiston. The county is named for the Umatilla River.
Umatilla County was created on September 27, 1862, out of a portion of Wasco County. Adjustments were made to the county's boundaries following the creation of Grant, Morrow, Union, and Wallowa Counties. This legislative act also designated Marshall Station as the temporary county seat. An 1865 election selected Umatilla City, now known as Umatilla, as the county seat. With the development of wheat farming, population shifted to the north and east parts of the county, and a subsequent election in 1868 moved the county seat again to Pendleton.
The Umatilla Indian Reservation was established by the Treaty of Walla Walla in 1855. The Umatillas, Walla Wallas, and Cayuse tribes were resettled there, and is located immediately southeast of Pendleton.
EZ Wireless of Hermiston officially opened on February 4, 2004, one of the largest known Wi-Fi wide area networks in the United States, covering parts of Umatilla County, Morrow County and Benton County, Washington. Although created to facilitate communications among local police, firemen and EMT workers who immediately respond to possible accidents or terrorist attacks on the Umatilla Chemical Depot, where the U.S. Army maintained a national arsenal of nerve gas, the network can be accessed in some places by the public for free.
According to the U.S. Census Bureau, the county has a total area of 3,231 square miles (8,370 km2), of which 3,216 square miles (8,330 km2) are land and 16 square miles (41 km2) (0.5%) are covered by water. It borders the Columbia River across from Washington.

Make-up of Umatilla County voters
Like all counties in eastern Oregon, the majority of registered voters who are part of a political party in Umatilla County are members of the Republican Party. In the 2008 presidential election, 59.77% of Umatilla County voters voted for Republican John McCain, while 37.16% voted for Democrat Barack Obama and 3.07% of voters either voted for a third-party candidate or wrote in a candidate. These numbers show a small but definite shift towards the Democratic candidate when compared to the 2004 presidential election, in which 65.8% of Umatilla Country voters voted for George W. Bush, while 32.8% voted for John Kerry, and 1.4% of voters either voted for a third-party candidate or wrote in a candidate.
The gold rush of 1862 brought miners and stock raisers to the mountains and grasslands of Umatilla County. Another stimulus was the arrival of the railroad in 1881, opening the region to the development of dry-land wheat farming. Water for irrigation has been key to economic diversification and growth, most recently in the Hermiston area, where potatoes, onions, corn, and more than 200 other crops are grown commercially. Low-cost power through Umatilla Electric Cooperative and good freeway access are also driving growth in the Hermiston area, with amazon.com developing large data-center operations there, and major distribution facilities for Walmart, FedEx, and UPS are all located in Hermiston.
Umatilla County is generally divided into three distinct economic and cultural areas, which are the West End, the Pendleton area, and the Milton-Freewater area. Although each of these communities shares some economic ties, the distance between each creates three very distinct communities. The West End includes the communities of Hermiston, Umatilla, Stanfield, and Echo. The Pendleton area includes Pendleton, Pilot Rock, Adams, and Athena. The Milton-Freewater area is largely tied to the Walla Walla, Washington area, and is considered a part of the Walla Walla Metropolitan Planning Organization. The similarities between the areas has created a long-standing rivalry, particularly between the West-End and the Pendleton-area, with regard to economic opportunity and public resources. The West End, led by Hermiston as its largest city, is now nearly twice the size of the Pendleton area, and is projected to be nearly three times the size of the Pendleton area by 2035.
