Abagadasset River

Merrymeeting Bay is a large freshwater tidal bay located in the U.S. state of Maine. Merrymeeting Bay's unusual geography defies common landform terms. It is not what is usually meant by the word bay. It is somewhat like an estuary but it has fresh water with very little salt. Geologically it is described as an "inland delta" and biologically as "tidal riverine."The head of Merrymeeting Bay is generally considered to begin at the southernmost point of Swan Island. Bordering towns and cities include Bath, Brunswick, Topsham, Bowdoinham, Dresden, and Woolwich. Public access to the bay is gained mainly from public docks on one of the contributing rivers in Brunswick, Bath, Richmond, and Bowdoinham.
