The Blue Flag is being raised over Colchester Harbour Marina today.
The marina is one of just eight in the country along with 27 beaches to receive the international Blue Flag eco-certification this year.
The Blue Flag program is an initiative of the non-profit group Environmental Defence and is celebrating its 30th anniversary after originating in France.
The program requires beaches and marinas to meet standards for water quality, environmental management, education, safety and services.
It's the only Blue Flag along Lake Erie in Essex County with the only other one being in Port Stanley.
