San Elijo Lagoon Inlet Opening

Tidal Circulation Returning to San Elijo Lagoon

The inlet at Cardiff State Beach, which connects San Elijo Lagoon to the ocean, is once again closed due to accumulated sand and sediment from winter storms and high waves. This blockage affects the lagoon’s tidal circulation, resulting in flooding and water quality degradation. But we are diligently monitoring conditions to ensure healthier tidal circulation returns.

Did you know that Nature Collective monitors water temperature, pH, turbidity, salinity, chlorophyll, oxygen levels, and more every 15 minutes, 24/7? Monitoring is crucial
in determining when to conduct our annual inlet excavation.

We have scheduled an inlet excavation beginning Monday, March 11. Work will occur at the San Elijo Lagoon inlet Monday – Friday. The first five days will focus on excavating the inlet channel, and then moving sand to Cardiff State Beach. At this time, we anticipate the project to conclude on Friday, March 22.

Nature Collective will continue closely monitoring the San Elijo Lagoon and the inlet.

Your donation makes urgent monitoring like this possible. Because of you, wildlife of all kinds, including endangered plants and animals, have more habitat to thrive.
