The Largest Estuary
Chesapeake Bay is the largest estuary in the United States. An estuary is a place where fresh water from rivers mixes with salt water from the sea, creating a special kind of partly enclosed coastal water. Chesapeake Bay, located on the U.S. east coast, is the biggest such body of water in the country.
A Bay Fed by Many Rivers
The Chesapeake stretches about 200 miles from north to south and is bordered mainly by the states of Maryland and Virginia. It is fed by a vast network of rivers and streams, with water draining into it from parts of six states and the District of Columbia. More than 100 rivers and streams empty into the bay.
A Rich and Productive Place
Chesapeake Bay is famous for being one of the most productive bodies of water in the world. Its mix of fresh and salt water creates an ideal habitat for an enormous variety of life. Hundreds of species of fish, along with crabs, oysters, and other shellfish, depend on the bay. It is also a vital stopping point for migrating birds, making it a treasure for both wildlife and people.
