It blows my mind that people would be upset about attempts to save the swamp.

I could be wrong, but that research covers the exact issues Louisiana is facing with the construction of levees to prevent flooding. This project is meant to "undo" that.

Yeah, we’re in kind of a do nothing, surely lose it- do something maybe save it or at least slow down losing it kind of situation. The swamp ain’t just gonna get better on its own.

Not as familiar with Louisiana so I’ll stick to talking about the Everglades and those of you that are familiar with the swamp can decide if it’s the same or not. What it’s done in Florida is push nutrient rich water into the canals where algae blooms have taken over. This has starved the waters for oxygen so in addition to it being unsightly and smelly it’s also killed or driven out fish.

People argue over the red tide because it generates offshore, but everyone does agree that the nutrient runoff isn’t helping.

To simply, man took annual (or semi annual) freshwater away from the swamp with the levees. The freshwater used to naturally flow into there.

The swamp is dying without it, so this is mans attempt to restore some of what used to naturally happen.

Edit: I get that these projects aren’t exactly free, but if you build siphons that have the capability of being opened or completely shut off I don’t see a down side other than cost.

Maurepas had an algae bloom just last year. We also had a huge amount of nutrient dense fresh water. I believe the key is keep the water moving. This diversion should do that, as well as keep the salt water intrusion down. Hopefully the people planning and designing this know more than I do.

This gets me so excited that the swamp could come back! It sucks that it will take another few years just to get started.

But will this diversion be able to build any land, or will it be mostly moving water and not sediment?

Check out the second video in the OP, but the answer to your question is yes.

I’m gonna assume I’ll be too old to enjoy the new land that could or would be built by the sediment.

I can remember fishing blind river as a 8 year old in 1973 and the fishing was unreal...... insanely ridiculous decline by 1983..... and it just kept on going.... would take very little time for fishing to improve....

Oh I know the fishing can turn around quickly. I was talking about sediment deposits actually building land.

I think the issue with Maurepas Swamp is that with it being cutoff from the Mississippi River by the river levees, the combination of allowing saltwater intrusion into the swamp and salvinia taking over in all the stagnant water and killing off all the other aquatic vegetation.

The idea with this diversion is to have the river water be able to flush the swamp in the spring when the river gets high, allow sediment to rebuild some land, and the freshwater influx to allow cypress and other trees to grow again in parts of the swamp that were dying due to salinity increasing.

Unfortunately, we'll probably look around in 20yrs and wonder why nothing's been done and where the money went.

Just curious, does/will the level of Lake Maurepas affect the flow of it's tributary rivers?

Sorely needed to save the swamp, but guessing it won’t do wonders for the saltwater fishing at the twin spans, trestles and such.


This will definitely change the salinity levels in Lake Pontchartrain over the next 10 years with 2000 cfs pumping out of Maurepas freshwater diversion but then couple this with the Mid-Breton diversion project which will pump 35,000 to 75,000 cfs of water into Lake Borgne and the impact will be significant for our fishery.
