A Closer Look

Every year, Moses Lake hosts the Grant County Fair, which is a five-day August fair in the heart of the Columbia Basin, where large-scale irrigated agriculture transformed the landscape after the completion of Grand Coulee Dam. The fair celebrates the potato, corn, and livestock production that defines this vast agricultural county.

Fair Highlights

Livestock shows, 4-H competitions, carnival rides, fair food, rodeo, and grandstand entertainment draw visitors from across Grant County's farming communities.

Planning Your Visit

Moses Lake offers excellent bass fishing and water sports — the sprawling lake system is perfect for a fair weekend getaway.
