Bayou Black

[southern custom]

Anyone fish the Bayou Black area out of Bob's lately? And also, does anyone know the best tide gauge to look at for the area. Been years since I fished down there and I can't remember.
Another question is where does the brackish water start. I used to fish the Turtle Bayou area and I don't remember it being brackish. Is there salt as far north as the Orange Grove?
Thanks Y'all!
