Long ago, Native Americans lived here. They had different names for the river. One name meant "river of swans." Captain John Smith made a map of the river in 1608. The name "Potomac" became official in 1931. The river is very old. It is at least 3.5 million years old. Some say it is much older. The river has many branches. The North Branch flows through Maryland and West Virginia. The South Branch flows through Virginia and West Virginia. These branches meet to form the main river.
