In 1990, Casco Bay was designated an "estuary of
national significance"and included in the U.S.
Environmental Protection Agency's National Estuary
Program, established in 1987 to protect nationally
significant estuaries threatened by pollution,
development or overuse. As a result of this
designation, the Casco Bay Estuary Project (CBEP)
was formed with the mission of preserving the
ecological integrity of Casco Bay and ensuring
compatible human uses of the Bay's resources
through public stewardship and effective
management.
