Penobscot Bay is an inlet of the Gulf of Maine and Atlantic Ocean in south central Maine. The bay originates from the mouth of Maine's Penobscot River, downriver from Belfast. Penobscot Bay has many working waterfronts including Rockland, Rockport, and Stonington, and Belfast upriver. Penobscot Bay is between Muscongus Bay and Blue Hill Bay, just west of Acadia National Park.
11,000 years ago, at the beginning of the Holocene epoch, the Gulf of Maine's sea level fell as low as 180 feet (55 m) below its present height. Penobscot Bay was then a continuation of Penobscot River that meandered through a broad lowland extending past present day Matinicus Island.
Penobscot Bay and its chief tributary, Penobscot River are named for the Penobscot Indian Nation, which has continuously inhabited the area for more than ten thousand years, fishing, hunting and shellfish gathering in and around the bay and river. A part of the Wabanaki Confederacy, the Penobscot Indian Nation's present reservation includes Indian Island, north of Orono, Maine, and all the islands of Penobscot River above it. Ancient remains of their campsites dating back millennia have been found on the bay's shores and islands.
There are many islands in this bay, and on them, some of the country's most well-known summer colonies.
Historic Water Pollution Management. Penobscot Bay has been the receiving waters for sewage waste and industrial waste discharges from bay and river towns since the 19th century. Discharge treatment was primarily dilution until the mid 20th century when the federal government began requiring communities and businesses of all states to meet water pollution control standards.
