"The river runs to the ocean. I am just one drop of it. But all the

drops together become very strong. I am proud to be part of an

important environmental movement that is growing in San Diego with the

new generation." ~ Marina Pak, SDRPF volunteer (see Marina's story below)

Taking Action: Marina Pak Creates a Ripple of Impact for the River

Volunteer Marina Pak testing water quality of the San Diego River

From testing the water quality of the San Diego River each month to participating in community cleanups, caring for Grant Park, and providing youth with exciting nature learning experiences, SDRPF volunteer Marina Pak is creating a ripple effect of impact for the river and our community! 


When asked what fuels her passion for taking action for the San Diego River Watershed, Marina explains:


“I usually run, cycle and walk a lot along the San Diego River from

Normal Heights to Ocean Beach. My passion grows every time I see the

beauty of wildlife in the heart of San Diego’s urban life. When I came

to my first clean-up, I felt a strong sense of joy and satisfaction

from connecting with people who were doing something practical and

meaningful for nature - people who share the same values. It is very

different from reading theoretical books and articles about

environmental science; it is a real, direct experience full of pure

energy and delight.”


Taking action for the river is meaningful in different ways for the thousands of volunteers working to create a better future for it. For Marina the river is essential for her wellbeing and provides a place of peace. She reflects:


“My connection with water, plants, birds, and clean air keeps me

healthy and emotionally stable. I think the San Diego River creates a

very special, almost sacred atmosphere of harmony and peace - not only

around the watershed but for our entire city. New technology is

rapidly changing urban life, making it more and more dynamic, but the

river connects our past, present, and future. We definitely have to

work hard to save it for the next generations….”


For Marina, working hard to protect and restore our river means ensuring we are monitoring the health of the river to inform decision making. Because of volunteers like Marina, our monthly water quality data is used by environmental organizations, scientists, to track long term trends, identify patterns of pollution, and by government entities to make regulatory decisions, management plans and public health advisories. 


When asked why she wanted to volunteer for our Water Quality Monitoring Team, also known as RiverWatch, Marina explains:


“Collecting water-quality data has become one of my monthly habits.

This program gave me the opportunity to meet people with diverse

scientific backgrounds—engineering, hydrology, biology, chemistry,

medicine, environmental policy, and many others. The SDRPF staff and

volunteers are amazing people who are always willing to share their

knowledge and research experience…. I am so grateful to John Kennedy, who

introduced me to a systemic approach using many indicators and tools -

from measuring water current speed to analyzing satellite data. Our

team job supports annual water quality index reports, aligned with

NGSS. Now I share my knowledge about it with a youth club of the

Tijuana River. This work creates a ripple effect and builds bridges

between science and the public.”


Marina not only collects vital river data, she also helps care for Grant Park as a Grant Park Steward and helps our Education Team provide essential nature-based STEM education to local youth. Check out Marina's full volunteer story here.


Thank you Marina for the incredible work you are doing for the river and our community! Together, we are ensuring a brighter future for our amazing watershed and our region.
