Chesapeake Bay Watershed
The Chesapeake Bay watershed extends about 500 miles south from the headwaters of Otsego Lake, near Cooperstown, New York to the Atlantic Ocean and Suffolk, Virginia. It extends east from mountain streams near Blacksburg, Virginia to Berlin, Maryland (near Ocean City). It is essentially a giant, sprawling system of rivers that all drain into one shallow tidal basin, the Chesapeake Bay and its tidal tributaries (average depth, only 21 feet).
More than 100,000 streams, creeks, and rivers thread through the Chesapeake Bay watershed—the area of land that drains into the Bay. They form an intricate web that connects each of us and our communities to the Bay.
Each of the streams, creeks, and rivers has its own watershed. These small subwatersheds form larger watersheds that flow into larger rivers. In the end, these larger watersheds all drain into the Chesapeake Bay and form the Chesapeake Bay watershed.
