In 1990, Casco Bay was designated an “estuary of national significance” and included in the U.S. Environmental Protection Agency’s National Estuary Program, which was established in 1987 under the Clean Water Act to protect nationally significant estuaries threatened by pollution, development or overuse. As a result of this designation, the Casco Bay Estuary Partnership was formed.
The Casco Bay Estuary Partnership, one of 28 National Estuary Programs nationwide, is a collaborative effort of people and organizations interested in protecting and restoring the Bay. Our partners include local, state and federal government organizations; non-profits; local businesses; citizens; universities and more.
