San Diego River Community Science Surveys

RiverBlitz is a field survey of the lower 20+ miles of the San Diego River.

3- 6 person teams of volunteer with a trained leader walk the riverbed in the City of Santee and San Diego and document what they see on a special app. In the spring, non-native invasive plants are recorded. In the fall, trash and other pollution is recorded.


This data is informs our programs throughout the year, plays an important role in developing a State of the River report, and is shared with mulitiple partners.

Each team gets a specific segment they are responsible for documenting. They are guided by a trained leader who works to ensure it is a safe, fun and meaningful experience.

How RiverBlitz Works:

  1. Surveys take place on Saturdays and Sundays in April and October each year.
  2. Teams are assigned to sections of the River each of which take about 2 -3 hours to survey. Teams are joined by a trained leader, so no experience is necessary.
  3. Surveys record non-native plants, trash, and park problems.
  4. Data is compiled into a State of the River Report which is available to the public.
  5. Data guides future clean-up events, projects and other actions.

Team Leader Training for the surveys are held in March and September! Email to learn more and to sign up for the next training.
