In 1883, Lincoln County was created from a portion of Spokane County, and four days later a portion of its area was split to createDouglas County. There have been no further alterations to its boundary since that time.[6] The name Sprague County was originally proposed, in honor of GeneralJohn W. Sprague, until objections from legislators resulted in the name Lincoln County being used in the final bill.[7] Its 2,317 square miles make it the eighth-largest by area in the state.
Centuries ago, the area now covered by Lincoln County contained an east–west passageway used by indigenous peoples. Aspring near the present-dayDavenport created a large overnight camping place.
The earlyexploration of the Northwest Territory by Lewis and Clark did not reach as far north as the Lincoln County expanses. The first recorded entry by European explorers was ofDavid Thompson, a scout for theNorth West Company, who traversed the area in 1811. He noted physical locations in present-day Lincoln County. He described Hell Gate Rapid (calling it 'Strong Rapid'). That stretch of theColumbia River is now tame, because of the presence ofGrand Coulee Dam.[6] After this, there was considerable exploration by fur trappers and others, including famed Scottish botanistDavid Douglas in 1826.[6]
Possibly the first permanent non-indigenous resident of the area was R.M. Bacon, originally fromBoston, who began raising cattle around Crab Creek in 1871. When the first post office was established in the county, Bacon was its postmaster.[6]
Emigration into the area accelerated in the late 1870s. Completion of theNorthern Pacific Railway in 1883, and construction ofFort Spokane (1880-1882) hastened settlement.
Lincoln County lies on theChanneled Scablands, known as the Big Bend Plateau. It lies 1,500-2,500 feet above sea level, with a system of channels eroded into bedrock by glacial rivers and streams, flowing from northeastern Washington.
Lincoln County climate is hot/dry in the summer, cold/moderately humid in the winter. Due to the relatively level terrain (about 1,200 feet difference from lowest to highest elevations), temperatures tend to vary little from east to west. Precipitation varies from an arid condition in the western part of the county to semi-arid in the northeast. The entire area lies in the dry intermontane basin between the Cascades and the Rocky Mountain System. Precipitation (10-20 inches annual rainfall) is a major controlling factor in agriculture. Precipitation in the Big Bend region is highly variable; from 8 inches in the west to 20 inches in the northeast.
Monthly temperature averages range from below freezing in mid-winter to highs of 65-71 °F in mid-summer.[6]

Like neighboring Adams County, Lincoln County is one of the most conservative counties in Washington. The last Democratic presidential candidate to carry the county wasHarry Truman in1948. In 1964, it was one of only three counties in the state to be carried byBarry Goldwater, and was the nation's northernmost county or equivalent to vote for Goldwater.[18] In the last nine presidential elections, no Democratic candidate has received more than 36 percent of the county's vote; the last Democratic gubernatorial nominee it backed wasBooth Gardner in1988, duringa major drought and farm crisis.[19] In2016,Donald Trump won over 70 percent of the county's vote, making it his strongest county in the state.[20][21] In2024, the county was one of only two in Washington State, along with neighboringStevens County, to give all ten statewide Republican candidates over 70% of the vote.

The county is dependent on agriculture, primarily wheat farming. Lincoln County is generally considered the second-largest producer of wheat in the United States (followingWhitman County, Washington), sometimes producing 25 million bushels (680,000 t) per year.[23] Only about 500,000 of 900,000 acres (2,000 of 3,600 km2 (1,390 sq mi)) of farmland in the county are planted in any given year due to the practice of typically harvesting one crop every two years ("summer-fallow"), a necessity in a region with only 12 inches (300 mm) of precipitation annually.
Livestock husbandry is also a significant county activity, although to a significantly lower degree. For example, in 1954 the county was #3 in the state for crop income, but was only #21 in the state for income from livestock and livestock products.[6]
