About a fifth of the county's residents live in the Greater Omak Area. The county forms a portion of the Okanogan Country. The first county seat was Ruby, which has now been a ghost town for more than 100 years.
Okanogan County was formed out of Stevens County in February 1888.[5] The name derives from the Okanagan language place name ukʷnaqín.[6] The name Okanogan (Okanagan) also refers to a part of southern British Columbia.
History
Before Europeans arrived, the Okanogan County region was home to numerous indigenous peoples that would eventually become part of three Indian reservations referred to as the Northern Okanogans or Sinkaietk, Tokoratums, Kartars and Konkonelps. They spoke in seven types of Interior Salish languages related to the Puget Sound tribes. The Okanogans experienced a favorable climate, camping in the winter, hunting bears in the spring, catching fish in the summer and hunting deer in fall. The camps consisted of teepee-like longhouses built with hides and bark. Women gathered nuts and berries. A popular destination for this was the Kettle Falls, where the Columbia River dropped some 20 feet (6.1 m).
Due to its remoteness, the Okanogan County area was one of the last in Washington settled by Europeans. It was an early thoroughfare used by prospectors to gain access to other communities, such as British Columbia. By the 21st century, the region specialized in agriculture, forestry and tourism. Electric producer Grand Coulee Dam was constructed between 1933 and 1942, originally with two power plants, around the Okanogan and Grant counties at the former's southern border.[7]

Politics
Okanogan County was once a national bellwether county in U.S. presidential elections, voting for the nationwide winner in each presidential election from 1904 to 1992. In fact, it became the longest-running national bellwether after Crook County, Oregon, voted for George H. W. Bush in 1992. However, it has become a Republican-leaning county since 1996, when it voted for Bob Dole, with the longest national bellwether status passing on to New Castle County, Delaware.[25]
