ケネベック川
Merrymeeting Bay is linked to the Gulf of Maine and the Atlantic Ocean by the Lower Kennebec River, a long saltwater tidal channel. The Lower Kennebec River and Merrymeeting Bay are known collectively as the "Kennebec Estuary". Merrymeeting Bay's connection to the Lower Kennebec River is via a slot in the bedrock called The Chops, an area of converging water flows known to be hazardous to boaters.
