What is it?
Stream monitoring is how Rockville creates the report card on the condition of its three watersheds – Cabin John, Rock Creek and Watts Branch. Volunteers, working under the direction of the City's Environmental Division, determine the "grades" by monitoring designated areas of a stream for aquatic insects, chemical contaminants and physical appearance.
Why get involved?
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.
What do I have to do?
To get involved, you must attend classes in stream monitoring. You will need to commit to monitoring a stream site twice a year – once in March or April and again in October. The City will provide collecting nets, field tables, collecting pans and microscopes. You provide your time and proper footwear for wading into streams.
Stream Report Card
The City of Rockville's State of Our Streams report outlines the health of the local streams as assessed by volunteers participating in the Save Our Streams (SOS) program. This report will be updated annually and is based on water quality sampling, benthic macroinvertebrate (small organisms) inventory and habitat assessment. SOS volunteers collect this data in the spring and fall. Read a summary or view the full State of Our Streams report.
