The Chesapeake Bay's watershed—the area of land that feeds all the water draining into it—encompasses 64,000 square miles of streams and rivers, forests, farms and cities.

The map and stories below highlight the variety of ways that TNC is working across six states—Delaware, Maryland/DC, New York, Pennsylvania, Virginia and West Virginia—to protect and restore the Chesapeake Bay.
