Our Members

The Coalition is made up of over 230 local, state, regional, and national organizations that are working to restore clean water to the Chesapeake Bay watershed. Our groups span the entire watershed, with organizations in all six states and the District of Columbia. The power of the Coalition comes from the work and dedication of our members, who while working on different issues, come together for one common goal: clean water.
