The Chesapeake Bay is a 200-mile-long estuary and so much more.

Chesapeake Bay page

Running from Havre de Grace, Maryland to Norfolk, Virginia, the Chesapeake Bay is the nation's largest estuary, but it is so much more. The Bay has more than 50 major streams and rivers pouring into it daily and is impacted by hundreds of water sources pouring into those streams and rivers. It encompasses a watershed area covering about 64,000 square miles! The watershed runs from New York through 6 states before ending at the ocean so the environmental impacts on any part of this vast area will ultimately impact the ocean.
