Volunteer for the River Health Monitoring Team


The RiverWatch Team is a community science team that conducts monthly monitoring to keep tabs on the health of the San Diego River. Teams meet on Friday and Sunday.

If you are interested in learning more about the health of the River and the requirements to join the RiverWatch Team, please contact Sarah, the RiverWatch Coordinator at (619) 297-7380 or by email volunteer@sandiegoriver.org.


This passionate volunteer team is supported by staff. Our research team assists with data analysis, volunteer support and training, equipment management and other vital functions.

RiverWatch serves as guardians for the health of the San Diego River. The data they collect has been used to address pollution issues, advocate for policy change and promote understanding about our amazing river. By being in and along the river on a frequent basis, they are often the first to document pollution and other problems.


RiverWatch also collaborates with our youth education program. In this way, kids can take a meaningful in being guardians of the river, too!

Did you know it costs just $400 per month to operate this program?

You can support the important work of RiverWatch by becoming a River Guardian with a monthly gift. Join the team with a monthly gift of $5 or more today!

RiverWatch data and Water Quality Reports
Online Information Center

Learn more about river health monitoring!
The Team uses a compact electronic sonde generously donated by Sontek/ YSI, to collect real-time data on the temperature, dissolved oxygen content, acidity or alkalinity, conductivity, and nutrient content of the River water at 15 different locations along the River. These parameters are used to provide a current picture of the state of the River water. The monthly monitoring results help provide an ongoing picture of how the River changes from season to season, and how that may affect the habitat, plants, and animals that live in and along the River. In this way, it is important for understanding the health of the San Diego River.

The Team has also expanded its outlook to include more monitoring parameters. Water quality measurements of nutrients (phosphate and nitrate) are now taken on a monthly basis. In addition to documenting the presence of trash, invasive plants, and riparian fauna, the team now also monitors seasonal changes in river water quality characteristics for such metrics as odor, color, clarity, flow and undesirable substances.



Help us keep the River beautiful for the next generation.
