The Great Baltimore Oyster Partnership

The Great Baltimore Oyster Partnership (previously the Healthy Harbor Oyster Partnership) is a project of the Waterfront Partnership of Baltimore and the Chesapeake Bay Foundation. It is part of the Healthy Harbor Initiative to make the Baltimore Harbor swimmable and fishable by 2020. The goal is to raise spat (baby oysters) in a protected environment until they are mature enough to survive on their own in the Chesapeake Bay.

The Partnership was launched in October 2013 as the Healthy Harbor Oyster Partnership. In 2014, the program expanded and changed its name to the Great Baltimore Oyster Partnership. After two successful years, the Partnership set a goal in 2015 to plant five million oysters in Baltimore's Patapsco River by 2020.

Over nine months, volunteers take care of the growing oysters. In the spring, the mature oysters are transported to a protected oyster reef near Fort Carroll in the Patapsco River.
