The largest bay in the United States is the Chesapeake Bay.
The Chesapeake Bay, located along the mid-Atlantic coast, is not only the largest estuary in the U.S. but also one of the most significant in North America. It spans approximately 200 miles in length and covers an area of about 4,479 square miles. The bay is surrounded by the states of Maryland and Virginia, and it features a diverse ecosystem that supports a wide range of wildlife, including various fish, crabs, and waterfowl.
Chesapeake Bay is historically important as well. It has played a crucial role in the region’s economy and culture, from fishing and crabbing to tourism. The bay’s watershed, which encompasses more than 64,000 square miles, includes parts of six states, making it a vital resource for the entire area. Protecting and preserving the Chesapeake Bay is a priority for local governments and environmental organizations, given its ecological and economic significance.
