Welcome to the Society for Freshwater Science Member Portal

The Society for Freshwater Science (SFS) is an international scientific organization whose purpose is to promote further understanding of freshwater ecosystems (rivers, streams, lakes, reservoirs, and estuaries) and ecosystems at the interface between aquatic and terrestrial habitats (wetlands, bogs, fens, riparian forests, and grasslands). The society fosters the exchange of scientific information among the membership, and with other professional societies, resource managers, policymakers, educators, and the public. Society members study genetics to community structure of freshwater organisms, freshwater ecosystem function, physical processes that affect freshwaters, and linkages between freshwater ecosystems and surrounding landscapes. Applied aspects of their science include habitat and water quality assessment, conservation, fisheries and invasive species management, integrated water resource management, and restoration.

The Society is committed to providing numerous tangible and intangible benefits to its members and the greater community. Membership in SFS is open to anyone who is interested in freshwater ecosystems.
