Useful information:
The Ohio River is without doubt a remarkable river in North America. A special feature is that every single one of its 1579 kilometers is navigable.

Of course, this only works because the source is a confluence of existing rivers. This is exactly how the Ohio River is formed in Pittsburgh in the US state of Pennsylvania. The Allegheny and the Monongahela flow into each other there.

Another special feature is the mouth of the Ohio. It does not flow into an ocean, but ends in one of the most famous and longest rivers in the world. Near the city of Cairo in the state of Illinois, the Ohio River flows into the Upper Mississippi and thus becomes an important part of its river system.

The Ohio used to be a comparatively shallow river. It was only a few meters deep in places, making it impassable for larger ships. Gradually, from the end of the 19th century, the Ohio River was systematically deepened and dammed. This finally made the entire length of the river navigable for inland shipping.
