Dredging in the East + Central Basins, and Inlet, Now Complete as Restoration Enters New Milestones

In just a year and a half since groundbreaking, tidal waters are flowing deeper and farther into San Elijo Lagoon.

We bid Fair Winds to the ever-steady Ross Island Dredge No. 10. This specialized dredge is moving on to the Deep Water Ship Channel in Stockton, California for work in the San Joaquin and Sacramento rivers. Over the past few seasons, the Dredge No. 10 deepened and widened tidal channels for the enhancement of tidal flow farther into San Elijo Lagoon.

In coming months, you can expect to see native plant revegetation occurring in these two basins. We’ll keep you informed as work begins.

News in the West Basin
The smaller Dixon Marine’s dredge, John Debin, completed sand dredging operations to make the inlet channel deeper. The removed sands were moved to the Central basin near the overdredge pit. This sand will be used to create the avian nesting area. Now the John Deblin is in the West Basin, behind Ki’s Restaurant, heading toward Harbaugh Seaside Trails, as it dredges the new channel in the West Basin.

High Tide Hangout for Birds
After the overdredge pit is filled, this area will become low salt marsh habitat. It will be contoured to allow for a few higher elevation points. This gives Ridgeway Rails a place in the middle of the lagoon to retreat during higher King Tides, for example.

Nesting SiteAbove: Sand in the Central Basin will be approximately 5 feet higher at project completion. This will create an avian nesting area for Snowy Plovers and California Least Terns.
