Casco Bay is an estuary--where rivers meet the sea. This nationally
significant embayment has been recognized for its richness and
diversity of marine life and is home to both endangered and
commercially important species.
The Casco Bay watershed comprises 986
square miles, stretching from the mountains near Bethel to the coastal
waters of Phippsburg and Cape Elizabeth. Home to nearly 20
percent of Maine's population, the watershed contains 42
municipalities, including some of the state's largest and fastest
healthy Casco Bay and watershed support a
rich ecosystem and contribute to the local economy and quality of life
in our communities through recreation, scenic beauty, waterfront jobs,
tourism, commercial harvest, and more. The Casco Bay Estuary
Partnership works to preserve the ecological integrity of Casco Bay and
to ensure compatible human uses of the Bay's resources, through public
stewardship and effective management.
