River Watch
Volunteer Water Quality Monitoring
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 Thursday and Friday 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 our RiverWatch Coordinator at (619) 297-7380 or by email volunteer@sandiegoriver.org.

The RiverWatch team uses a compact electronic sonde to collect real-time data on the temperature, dissolved oxygen content, acidity or alkalinity, conductivity, and nutrient content of water at 16 different locations along the River. These parameters are used to provide a current picture of the health of the River. 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 also monitors for nutrients (phosphate and nitrate) on a monthly basis at certain locations. 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.
