Our Waterkeeper Members

WATERKEEPERS® Chesapeake is a coalition of seventeen independent Waterkeeper programs working to make the waters of the Chesapeake and Coastal Bays swimmable and fishable. The members of Waterkeepers Chesapeake work locally, using grassroots action and advocacy to protect their communities and their waters. They work regionally to share resources and leverage individual organization strengths to expand each Waterkeeper’s capacity for on the water, citizen-based enforcement of environmental laws in the Chesapeake region.
