San Elijo Lagoon Inlet Facing Possible Closure

Sand has refilled the channel, and the lagoon is struggling to flush water out

As dedicated stewards and managers, the Nature Collective staff have been monitoring the inlet since the recent dredging, and our observations indicate a steady decline in the tide’s ability to flow in and out of the lagoon. Unfortunately, sand has refilled the channel, and the lagoon is struggling to flush water out, resulting in elevated water levels.

The lagoon is now caught between two determining environmental factors expected this weekend, which will determine whether it remains open but still muted or if it closes: 

-Expected surf height of 6-8 feet, and the wave energy that comes with it could move enough sand to fully block the channel.

-Coastal areas are expecting up to 2 inches of rain. If we receive enough, the momentum of the resulting storm flow down the Escondido Creek could create enough hydraulic force to push some of the sand out, delaying the inlet closure.

If the inlet closes, the resulting drop in dissolved oxygen and prolonged flooding will swiftly threaten marine life and critically impact habitats for endangered species.

We’ll keep you posted as this situation develops.
