Dolphin in Delacroix

You mean porpoise right? I see them most of the time. Even in pretty shallow ponds.

Saw a couple Sat morning by Lena Lagoon in Hopedale.

I have been fishing/hunting in the Delacroix area for about 25 or so years. They are not real common, but you will see a few inland from time to time. Four Horse is not that far in from Black Bay.You can check the Crooked Bayou gauge to see the salinity in that area.
