The Piscataqua River/Great Bay estuary is a shared coastal embayment that forms the southernmost boundary between the states of Maine and New Hampshire. This rich coastal bay provides critical ecological, economic, and social benefits to the southern Maine and coastal New Hampshire region. The Great Bay estuary is such an important coastal resource that it is officially recognized as a coastal area of national significance by both the federal National Estuary Program and the federal National Estuarine Research Reserve program. The Piscataqua River/Great Bay estuary is fed by many rivers in New Hampshire, and by the Salmon Falls River, Great Works River, and Spruce Creek water- sheds in Maine. Collectively, the land area that contributes water flow to this treasured bi-state estuarine system is referred to as the “Piscataqua Region.” Within Maine, this region includes portions or all of ten Maine communities: Acton, Berwick, Eliot, Kittery, Lebanon, North Berwick, Sanford, South Berwick, Wells, and York.
