Water Monitoring

Nature Collective staff prides itself in weekly water-quality monitoring.

Because we monitor the dissolved oxygen in the water, we can help protect many threatened and endangered animals in San Diego, as well as plants. Keeping tabs on the local waters means that we can make educated decisions. For instance, we can perform an emergency tidal circulation project if there’s not enough oxygen for the ecosystem to survive.

As an added benefit, this vital practice helps scientists + the larger community stay aware of the relative health (and any possible danger) of local water. In fact, our water stats even assist experts in monitoring San Diego water pollution.


years of Nature Collective staff conducting water quality monitoring – every week!


locations are tested each week.


is when the weekly monitoring happens – because it’s before photosynthesis begins. That way, dissolved oxygen is checked at its lowest point, ensuring aquatic life can survive.


minute passes between each sample collection via a measuring instrument, gathering dissolved oxygen, salinity, temperature, conductivity, turbidity, chlorophyll, pH, and depth stats.


gauge readings inform our team of the Escondido Creek’s health. Continuously gathering data point there, we can better understand the effects of rain (and more) on the lagoon – and the watershed as a whole.
