Petroleum County is one of the most deeply rural places in America. It spans an area of 1,655 square miles but is home to just 494 people. Winnett is the county seat and lone town in the county and has a population of 188. We are the least populous county in Montana.

Our community persists and serves a vital role in the functioning of America. Ranchers and farmers here produce high quality food and fiber for the world, while also managing a considerable portion of the last remaining intact, native prairie in North America.

This place matters – it matters to the ranchers who care for their land and livestock, it matters to the local community, it matters to those who benefit from hunting and fishing opportunities, and it matters to those who care about native prairie. The people, land, and animals coexist in a delicate balance, with each serving as support for the others. With passion for our community, and for our environment, we serve as stewards working to strengthen the resiliency of our community.
