Chesapeake Bay

The Chesapeake Bay (/ˈtʃɛsəpiːk/ CHESS-ə-peek) is an estuary lying inland from the Atlantic Ocean, and surrounded by the North American mainland to the West, and the Delmarva Peninsula to the East. It is the largest such body in the US. The northern bay is within Maryland, the southern portion within Virginia, and is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the bay's 64,299 square miles (166,534 km²) drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia) plus all of the District of Columbia.

The bay is approximately 200 miles (300 km) long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles (4.5 km) wide at its narrowest (between Kent County's Plum Point near Newtown and the Harford County shore near Romney Creek) and 30 miles (50 km) at its widest (just south of the mouth of the Potomac River). Total shoreline including tributaries is 11,684 miles (18,804 km), circumnavigating a surface area of 4,479 square miles (11,601 km²). Average depth is 21 feet (6.4 m), reaching a maximum of 174 feet (53 m). The bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point (near Annapolis) to Kent Island, and in Virginia by the Chesapeake Bay Bridge-Tunnel connecting Virginia Beach to Cape Charles.

Known for both its beauty and bounty, the bay is becoming "emptier", with fewer crabs, oysters, and watermen in recent years.
