A Brief History

Fresh as a daisy

Grant county was formed from Douglas County  on February 24, 1909, and named after President Ulysses S Grant.  The county seat is Ephrata, and the largest city is Moses Lake.

Native American cultures in the area included the Interior Salish, Wenatchi, and the Okanagan.

White settlers began to arrive in the mid-to-late 19th century, primarily with the goal of raising livestock.  Irrigation attempts began in 1898, but it would be years before real success. 

Three major railway systems tracked through the county; the Great Northern, Northern Pacific and the Chicago, Milwaukee & St. Paul Railroad.  The Columbia River was navigable in this area which allowed crops to be transported out of the area easily that also allowed towns like Wilson's Creek, Quincy and Ephrata to thrive.
