The Chesapeake Bay is an estuary in the U.S. states of Maryland and Virginia. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth located between Cape Henry and Cape Charles. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin.
The Bay is approximately 200 miles (320 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 (48 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 National Park Service strives to connect people to the opportunities and adventures throughout the watershed. Inspiring stewardship across this vast region supports recreation, business, tourism, learning, and a thriving natural resource for all to enjoy.

Series: Beach and Coastal Landforms
Our national parks contain diverse coastal landforms: high-energy rocky shorelines of Acadia National Park, quiet reef-lagoons within War in the Pacific National Historic Park, and the white sandy beaches of Gulf Islands National Seashore. Coastal landforms are, or have been, affected to some degree by the direct or indirect effects of waves, tides, and currents, and may extend inland for many miles.
