Volunteer Water Quality Monitoring


The RiverWatch Team is a citizen science team that conducts monthly monitoring to keep tabs on the health of the San Diego River. Teams meet on Friday and Sunday for monitoring. If you are interested in learning more about the health of the River and the requirements to join the RiverWatch Team, please contact Aixa, the RiverWatch Coordinator at (619) 297-7380 or by email volunteer@sandiegoriver.org.


COVID Update:
We are operating a limited RiverWatch program. Due to the pandemic, we keep the number of participants to just a few while maintaining the integrity of our data collection. This passionate volunteer team is supported by staff. Staff assist with data analysis, volunteer support and training, equipment management and other vital functions.

The team continues to serve be a guardian for the health of the San Diego River. By being on the river they not only collect data but also can see and smell changes to the river.

The data they collect has been used to address pollution issues, advocate for policy change and promote understanding about our amazing river. We also integrate this program with our vitual youth education programs (we can't wait to have the kids back out on the river in person!)

Did you know it costs just $300 per month to operate this program?

RiverWatch data and Water Quality Reports

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.

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.
