About this river

Monongahela River

The Monongahela River is a 128-mile-long river located in West Virginia and Pennsylvania. It was named after the Monongahela people who previously inhabited the area. The river played a significant role in the early industrialization of the United States, with coal being transported downstream to Pittsburgh. Today, the river is still vital for transportation, as well as for hydroelectric power generation. The river has several reservoirs and dams, including the Youghiogheny Dam and Reservoir and the Morgantown Lock and Dam. These structures help regulate water levels and provide recreational opportunities such as fishing, boating, and swimming. The Monongahela River is also important for agriculture, assisting in irrigation for crops in the surrounding areas.
