Grant County is a county located in the U.S. state of Washington. As of the 2020 census, the population was 99,123. The county seat is Ephrata, and the largest city is Moses Lake. The county was formed out of Douglas County in February 1909 and is named for U.S. President Ulysses S. Grant.
Grant County comprises the Moses Lake, WA Micropolitan Statistical Area, which is also part of the Moses Lake-Othello, WA Combined Statistical Area.
History
Native American cultures in the area included the Interior Salish, Wenatchi, and Okanagan. The first white settlers began to arrive in the mid-to-late-19th century, primarily with the goal of raising livestock. One government official described the area in 1879 as, "…a desolation where even the most hopeful can find nothing in its future prospects to cheer."
When railroads arrived they also brought new settlers, and the economy began a shift from ranching to dryland farming. This transition required the people to have ready access to water, and irrigation became a necessity. The first large-scale irrigation attempts began in 1898, but it would be years before real success.
With the influx of dryland farming, the county soon boasted access to three major railway systems; the Great Northern Railway, Northern Pacific Railroad and the Chicago, Milwaukee & St. Paul Railroad. In addition, the Columbia River in this area was navigable. This allowed crops to be transported out of the area easily. Towns like Wilson Creek, Quincy and Ephrata began to thrive.
The Washington State Legislature officially created Grant County on February 24, 1909, naming it in the memory of Ulysses S. Grant, the 18th president of the United States, and a major contributor to the Union victory in the American Civil War. The county seat was located in Ephrata. The area's population at the time stood at around 8700 people.
The Columbia Basin Project, which ultimately produced the Grand Coulee Dam with its associated irrigation and hydroelectric generating grid, was an outgrowth of the 1902 creation of the United States Bureau of Reclamation. When that agency began studying feasibility of projects in the Northwestern United States, competing groups from Spokane, Wenatchee, Ephrata and elsewhere advanced competing possibilities. One idea was to dam the Columbia River at Grand Coulee. This concept was approved in 1933, and construction continued in the following decades. The project would fundamentally change the region forever.
