Grant County

Grant County is an administrative region in Eastern Washington covering diverse terrain from flat valleys to rolling hills. Moses Lake serves as the economic hub, while Ephrata functions as the county seat where government offices are located.

The county was established in 1909, named to honor President Ulysses S. Grant. A major transformation came through large-scale water and irrigation projects that reshaped the entire region's economy and landscape.

The Interior Salish peoples shaped this region's heritage through their long presence and seasonal camps across the land. Today, farming communities reflect both traditional land knowledge and modern agricultural practices.

The region is easy to reach by highway, with flight connections available near Moses Lake. Visitors should note that summers are extremely hot, and bringing water is essential for any outdoor activity.

The region was once a dry, sparse landscape until massive water and dam projects turned it into one of the state's leading agricultural producers in just decades. Few places in the Pacific Northwest show such a stark transformation of the land.
