History and General Information
Grant County was created in 1864 from Wasco and Umatilla counties and was named for General Ulysses S. Grant. It shares boundaries with more counties (eight) than any other county in Oregon.
Grant County contains the headwaters of the John Day River, which has more miles of Wild and Scenic designation than any other river in the United States. More than 60% of the land in the county is in public ownership.
