Register here for the first oyster gardening workshops of the 2020-2021 season!

Note: Volunteer events are at reduced capacity as a Covid-19 precaution. Please register only if you are certain you will be able to attend. Thank you for your understanding.

We, along with the Chesapeake Bay Foundation and Baltimore businesses and residents like you, have come together to form the Great Baltimore Oyster Partnership.

In this program, baby oysters are grown at designated oyster garden locations in Baltimore’s Inner Harbor, September through June. At the end of the season, the matured oysters are taken by boat to a protected oyster sanctuary in the Patapsco River, where they will live out the rest of their lives.

In addition to restoration, the goal of the Great Baltimore Oyster Partnership is to train its volunteers to become community scientists and oyster advocates who can speak to others about the pollution challenges facing the Baltimore Harbor and the role that oysters play in improving water health.


The oysters we grow are for restoration purposes only and not for eating. We grow oysters because of their amazing ability to filter pollution out of the water and because of the critical habitat they provide.A full-grown oyster can filter up to 50 gallons of water every day!

Two hundred years ago there were enough oysters to filter all of the water in the Chesapeake Bay in less than a week. Today it takes the  remaining oysters over a year to filter the same amount of water.


If you’re an individual, you can volunteer to help us install and maintain our large public oyster gardens in Canton and near Federal Hill.

Oyster gardening events will be hosted the 1st and 2nd Saturday mornings of Oct-Dec and Mar-June, weather permitting.

Children 10+ are welcome. Contact for more information.
