Major Cities and Towns in Petroleum County, Montana
Winnett
Location and History
Winnett is the county seat of Petroleum County, located in central Montana, approximately 70 miles southeast of Lewistown. The town was founded in the early 20th century, and it was incorporated in 1911. It was named after the Winnett family, early settlers in the area who were involved in ranching and land development. The arrival of the railroad in the early 1900s helped to establish Winnett as a trading and service center for the surrounding agricultural community. Agriculture, particularly wheat and barley farming, has long been the backbone of the local economy, and the surrounding prairie landscape is well-suited for cattle ranching. The discovery of oil in the region in the mid-20th century led to a brief oil boom, which helped shape the town’s economic development. Today, Winnett remains a small, rural community with a focus on agriculture, energy production, and the oil industry. The town’s population has remained relatively stable, and it continues to serve as a hub for surrounding farmers, ranchers, and energy workers.
