I received 3 files from the Army Corps of Engineers depicting the Oyster Creek Channel after it was dredged. I clipped these files from them. The drawings are as of Aug 1. I remember the 40 buoy being knocked off line early this summer so I wouldn't necessarily trust that it's location is exactly in the same spot marked on these drawings. But based on going through there a few times I think it's pretty close. Notice how skinny it is right before the 38 buoy (file 64494). I went through there ~30 minutes after low tide yesterday and picked up readings of 3.5 feet right next to the 38 buoy.
