The Ohio River is a major river artery of the central United States, flowing in a generally southwestward direction from its origin in western Pennsylvania to its confluence with the Mississippi River at Cairo, Illinois. It is approximately 981 miles (1,579 km) long and is the largest tributary by volume of the Mississippi River.

Geography

The Ohio River begins at the confluence of the Allegheny River and the Monongahela River in Pittsburgh, Pennsylvania. It flows through or along the border of six states: Pennsylvania, Ohio, West Virginia, Kentucky, Indiana, and Illinois. The river serves as a natural boundary between several of these states.

The river's course is characterized by a series of locks and dams that help maintain a navigable channel for commercial shipping. Major cities along the Ohio River include Pittsburgh, Cincinnati, Louisville, and Evansville.

History

The Ohio River has played a significant role in the history and development of the United States. It was a primary route for westward expansion during the 18th and 19th centuries. The river was also a critical boundary during the American Civil War, serving as a dividing line between free and slave states.

The river's name is derived from the Seneca word "Ohi:yo'", meaning "good river" or "large creek". It was first explored by Europeans in the 17th century, and its strategic importance was recognized by both French and British colonial powers.

Ecology

The Ohio River basin is home to a diverse array of plant and animal life. The river supports numerous fish species, including bass, catfish, and walleye. The surrounding watershed provides habitat for a variety of wildlife, including deer, beavers, and numerous bird species.

Efforts to improve water quality and restore natural habitats have been ongoing, as the river has historically suffered from pollution due to industrial and agricultural runoff.

Economy

The Ohio River is a vital component of the U.S. inland waterway system. It supports a significant amount of commercial traffic, including the transportation of coal, petroleum, steel, and other goods. The river's ports and harbors are crucial to the economies of the states it borders.
