Buzzards Bay is a bay of the Atlantic Ocean adjacent to the U.S. state of Massachusetts. It is approximately 28 miles long by 8 miles wide. It is a popular destination for fishing, boating, and tourism. Buzzards Bay is often considered the finest sailing location on the East Coast and is frequently compared in terms of sailing conditions to San Francisco Bay. Since 1914, Buzzards Bay has been connected to Cape Cod Bay by the Cape Cod Canal. In 1988, under the Clean Water Act, the Environmental Protection Agency and the Commonwealth of Massachusetts designated Buzzards Bay to the National Estuary Program, as "an estuary of national significance" that is threatened by pollution, land development, or overuse.
