No overwash occurred during the last high-tides, but probably during December there were overwash events in some parts of Barreta Island.
|Shell debris alignments consistent with overwash.|
Aeolian rework of the barrier surface is visible in many areas, either by ripples, lag surfaces or depositions behind obstacles on the surface. Some vegetation is covered by this process.

The lagoon margin is varied along Barreta Island. In places, a tidal flat exists, while in others there is a sandy beach adjacent to the tidal channel.

During this survey, barrier erosion was noticed on the lagoon beach, which is likely related to changes in the inner channel currents.
