Perego's Lagoon

A series of photos illustrating the role of overwash in shaping barrier beaches is a standard element in many of my beach talks and one of my favorite examples is Perego's Lagoon on the west side of Whidbey Island. This Saturday I was up on Whidbey (at Sound Waters) and just before my presentation, someone mentioned that waves had recently breached that spit.

So I skipped out on the third session of the day and drove up to Ebey's Landing to check it out. Sure enough, there was a small breach in the berm crest near the south end and a fresh deposit of sand, gravel, and logs in the lagoon. This looks pretty small compared to some of the older, preserved ones nearby, but still very neat to visit before it patches itself back together (which it will probably do pretty quickly).


Although I don't know for sure, this likely occurred on December 20th, when a strong wind storm coincided with a high tide and a strong surge. There have been reports, and numerous videos, showing the fierceness of that storm, particularly in northern Puget Sound (Birch Bay got hit really bad).

Here are some previous posts from Perego's, some of which show the earlier overwash fans quite a bit better:
