Rockville Save Our Streams (SOS) volunteers are the first line of defense for city watersheds. By volunteering you will meet people who share your interest in protecting the environment. You will help Rockville by providing information to safeguard and improve the environmental habitat. Volunteers help expand the city’s capacity to study and protect Rockville's environment.
Volunteer stream monitoring is one of the ways that Rockville evaluates the health of its three watersheds – Cabin John, Rock Creek and Watts Branch. Volunteers, working under the Izaak Walton League of America system, determine the "grades" by monitoring designated areas of a stream for aquatic insects, chemical contaminants and physical appearance.
To get involved, you must attend a training in stream monitoring. You will need to commit to joining a monitoring team and monitoring a stream site twice a year – once in March or April and again in October.
