Does this seem about right?

Seems to me instead of keeping water “in the channel where the water’s from” it’s blocking what had been the natural flow of the water for thousands of years?

Also, with most of the blame frequently being placed on the ongoing raised developments contributing to the recent flood events (and rightfully so I imagine, but don’t know enough about that), wouldn’t Manchac Road also be a contributing factor preventing the natural flow of water to Spanish Lake as it’s practically a man-made levee?

Good points. I don't know if the aqua damn runs as far as your drawn in line.

Does anyone know if the parish dug out Manchac along that stretch? I seem to recall that being planned after 2016, but I don't know if it ever was.

Those aqua damns are about 3 feet tall I think. So in theory I guess it can't hold back anything more than 3 extra feet before it runs over into the swamp.

That’s the area. Not sure exactly where though. And yes the road is already a levee keeping Manchac from going into Spanish Lake and the swamp around it.

Bayou Manchac is kinda weird in that it is actually higher in the middle than it is near the Mississippi and the Amite. Its natural behavior was screwed up when it was cut off from the Mississippi. Ascension and Iberville have to use pumps to help water flow out sometimes.
