Found Barataria Bay depth map (with link)

[Ray]

I have Mapsource on my lap top. You can update it any time you want.
No matter what or when, they still show the old islands at the mouth of
Turners Bay, that have been washed away for almost 20 years.
Same with Barataria and Terrebone Bays. Still shows land that is no longer
there.

If you do use them for inshore, be sure to stay clear of where they show
land. It might still be there, just a few inches under the water.
