The Antietam Creek watershed is a small but important part of the Chesapeake Bay watershed. More than half of the state lies within the Bay watershed. Pennsylvania contains two major Bay watersheds: the Potomac, with 1,600 square miles; and the Susquehanna, with 21,00 square miles. Together, they total 40% of the entire watershed.
