Chesapeake Bay Watershed Region Freshwater Mussel Partnership

The Chesapeake Bay Watershed Region Freshwater Mussel Partnership is a voluntary affiliation of stakeholders drawn by our interest in freshwater mussels to:

  • Advance and promote Conservation & Restoration; and,
  • Evaluate Water Quality best management practices (BMPs) to lessen excess nutrients and sediment in tributaries to the Bay.

Interest in freshwater mussels throughout the Chesapeake Bay Watershed is growing and for good reasons, such as:

  • Freshwater mussels are among North America’s and the Bay Region’s most endangered group of organisms
  • Freshwater mussels have unique life strategies linked to individual fish species
  • Much like benthic macroinvertebrates, freshwater mussels are indicators of existing water quality conditions in a stream
  • As they feed, freshwater mussels transfer suspended matter from the water column to the stream bed
  • Freshwater mussels are ecosystem engineers, capable of modifying aquatic habitat to make conditions more suitable for themselves and other organisms

About Us

The Chesapeake Bay Watershed Region Freshwater Mussel Partnership evolved mainly from the Chesapeake Bay Program’s Science & Technical Advisory Committee workshop (March 5-6, 2020): Incorporating Freshwater Mussels into the Chesapeake Bay Restoration Efforts and the National Fish & Wildlife Foundation and state of Maryland’s workshop (April 13, 2022): Broaden and Enhance Regional Freshwater Mussel Partnerships in the Chesapeake Bay.

In 2023, staff from the Susquehanna River Basin Commission transitioned to the role of coordinators for the Regional Freshwater Mussel Partnership. As coordinators, SRBC staff: facilitate communication among the Partnership members, Action Teams, and Steering Committees and with pertinent elements of the Chesapeake Bay Program; schedule Partnership Steering Committee meetings; coordinate an Annual Symposium; and manage resources and information for this web page.
