San Elijo Lagoon Conservancy Monitors the Health of Our Waters—Rain or Shine—During Lagoon Restoration

This past Tuesday, San Elijo Lagoon Ecological Reserve received nearly two inches of rain. With so much water flowing downstream in the Escondido watershed, and out to sea, it was time to pull on the rain gear and check on water quality.

Inclement weather? No problem. Water quality monitoring is a state requirement whenever it rains over half an inch.

SWPPP Sampling

L-R: Conservancy Habitat Management Director Bradley Nussbaum and Scientific Research Director Tim Stillinger sample pH and turbidity at La Orilla Creek for the Stormwater Pollution Prevention Plan on Tuesday, January 9, 2018.

This is an example of the Conservancy’s role in overseeing habitat quality control during the Reviving Your Wetlands lagoon restoration project. For the entire project and for years after, the Conservancy will continue to engage in stormwater sampling to ensure that the project is not causing any pollution or releasing sediments during a rainfall event.

The conservancy conducts sampling by measuring in five sites. We sample in four run-on areas, which means incoming freshwater sources from: Escondido Creek, La Orilla Creek, Joint Powers Authority (JPA) Channel and Rossini Creek. The fifth site is the runoff area at the San Elijo Lagoon inlet where waters flow and mix with the ocean.

If our runoff area—the lagoon’s inlet—should ever exceed the limits set by state regulators, our run-on, or incoming freshwater samples, should show that the out-of-bounds readings are caused by areas outside of the project and not by lagoon restoration.

If there were ever high pH or turbidity readings from our project, immediate steps would be taken to identify and remedy the problem.

  1. Hi, I’m enjoying the Lagoon Connections updates and appreciate SELC’s work to restore and protect this precious wetland! You always invite questions about the restoration, and I have one for you: my primary interest is the wetlands restoration, but the multi-tasking nature of this enormous undertaking is fascinating and I can’t get enough detail about every aspect. I have not been able to find plans and/or elevation drawings of both the rail and the freeway expansion projects. Can you point me in a direction?Thanks again for all you do!With appreciation,Don Chartrand858-437-2838

    1. Hi Don, thank you for following Lagoon Connections! And for asking us your question. We have reached out to the Build North Coast Corridor (Build NCC) partners who are in charge of railroad and I-5 construction and someone will be contacting you directly. Also, there is a lot of in-depth information on all aspects of the Build NCC project online at (in case you haven’t visited this site). Thank you again and we’ll continue to keep everyone updated on Reviving Your Wetlands lagoon restoration.
