Nanticoke River

The Chesapeake Bay in the Mid-Atlantic region is the US's largest estuary. It receives water from ten major rivers and several other smaller rivers, streams, and creeks flowing out of West Virginia, New York, Pennsylvania, Virginia, Maryland, and Washington DC. One of the bay’s largest and most productive rivers is the 103.5-km long Nanticoke River. This river originated in southern Delaware and gently flows southwest through forests, marshlands, and farmlands to Tangier Sound. The river’s upper part is Delaware’s largest watershed, with almost half the Nanticoke watershed located in Delaware. About 20% of the river’s watershed is protected as a nature conservation area and contains a variety of animals and plant species.

Captain John Smith, English explorer, soldier, and colonial governor traveled from Virginia to explore the Chesapeake Bay and its many rivers in 1608. John Smith hoped that one of the bay’s rivers would lead him to mythical wealth in the far east. While on his discovery journey, Smith came across the gently flowing Nanticoke River on the Delmarva Peninsula. He named the river after the Native American group that lived on the river bank. The gentle and peace-loving Nanticoke tribe thrived mainly on fishing and hunting. They also traded various commodities, including beads and animal pelts.
