Named for the Susquehanna River, which is a river located in the northeastern United States. At 464 miles long, it is the longest river on the American east coast that drains into the Atlantic Ocean. Also, it is the longest river in the continental United States without commercial boat traffic.
The Susquehanna flows through New York, Pennsylvania, and Maryland into the Chesapeake Bay. It forms from two main branches, with the "North Branch", which rises in upstate New York. The river drains 27,500 square miles. Including nearly half of the land area of Pennsylvania. The drainage basin includes portions of the Allegheny Plateau region of the Appalachian Mountains, cutting through a succession of water gaps in a broad zigzag course to flow across the rural heartland of southeastern Pennsylvania and northeastern Maryland in the lateral parallel array of mountain ridges. The river empties into the northern end of the Chesapeake Bay at Havre de Grace, Maryland. Providing half of the Bay's freshwater inflow.
