Grant County

In Grant County, you can find the communities of Canyon City, Dayville, Granite, John Day, Long Creek, Mt. Vernon, Prairie City, and Seneca. The State of Oregon is nearly as large as the entire country of France and embraces more land than England, Ireland and Scotland combined. Grant County itself is nearly the size of Connecticut. Its boundaries contain all the headwaters for the four forks of the John Day River. With such a vast abundance and diversity of natural resources — from the green rolling hills of the John Day River valleys to the timbered slopes of high alpine lakes and mountains — Grant County offers a lot of opportunities for residents, tourists and business owners. Fresh water helps to define Grant County with most of Grant County being drained by the four forks of the John Day River, all of which have their headwaters in the county. The John Day River system drains some 7,900 square miles. It is the third longest free-flowing river in the lower 48 states and has more miles of federal ‘Wild and Scenic River’ designation than any other river in the United States and flows into the Columbia River.
