StreamWatch is an environmental monitoring program focused on the 766-square-mile (1,980 km2) Rivanna River watershed in central Virginia in the United States. The data StreamWatch collects helps communities in the city of Charlottesville and in Albemarle, Fluvanna, and Greene Counties maintain healthy streams and restore damaged ones. StreamWatch believes that "when diverse sectors of the community share fundamental agreement on the condition of a resource, the chances of sound, collaborative management are enhanced."
