re: Maurepas Swamp Duck Hunting

Some of it would have gone into the river. Not all. The banks of the Mississippi River are higher than the surrounding land pretty much everywhere south of highland road. Where I'm at the elevation of land is 25' above sea level. By the time you get to the beginnings of blind river elevation is probably barely above sea level. I don't think the land in Ascension, Baton Rouge, or Livingston drops as drastically, but the easiest path for all that water was the Maurepas Basin.
