There was some talk on the SNESA email group and I got this from an older post. If you look back on the messages you'll find more discussion on this topic.
Frow what I understand, they're supposedly going to dredge the big sand bar/flat to the west of the channel in the pond. This dredging is "habitat restoratation" for eelgrass, and is to remove all the sand brought in because the breachway was made permanent, and the "catch basin" inside the breachway was never dredged. The shallows east of the channel in the pond will be untouched.
