The Society for Freshwater Science (SFS) is an international scientific society whose members study 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).

[3] The executive committee is responsible for day-to-day business of the society and is made up of member officers elected by their peers.

[34] About once a year the journal publishes open-access fact sheets called BRIDGES that cover new ideas in aquatic science using non-technical language.

[44] SFS partners with the Stroud Center to provide an aquatic invertebrate taxonomic certification program for its members.

[47] 'Making Waves' is a podcast hosted by society members that comes out semi-monthly and discusses freshwater science for a general audience.

[49] SFS holds a leaf pack workshop at the annual meetings for local environmental groups and educators.
