re: Planned freshwater diversions will doom LA salt fishing



How about the whole state doomed if they DON'T do something?

re: Planned freshwater diversions will doom LA salt fishing


Sorry but i can't agree on this one. Being someone that lives so close to so much coastal erosion i have seen first hand how much land we have lost. I would rather have a further run to catch a speckled trout than have everything wash away. Fresh water into the marsh is a good thing almost instantly freshwater grasses take over creating land.

I bet. If you haven't fished an area in southern terrebonne in over a year chances are it doesn't look the same anymore and you may not even be able to find it.

land loss in Caenarvon is greater area that all deltas built by all freshwater diversions.


and that has nothing to do with storms?

If the levees had never been built in the 1920's, would we be having this discussion today?
Those levees were built almost 100 years ago with the engineering knowledge of that day.
That's what they though was the best thing to do at the time.
BTW, silent films, the Charleston and Prohibition were also popular in the 20's.

I will agree with you on one point Deege, diversions alone are worthless.

If the diversion has no sediment load then it will not work as intended/hoped.

If there is a sediment load then it will work beautifully.

As stated above the entire goal of the new diversions is to capture sediment and water in order to reduce the amount of dredging which is very expensive. It's a great example of the "work smarter not harder" philosophy.

Exactly.

Let nature do the work

I have access to some pretty valuable fishing data. I know where all the old islands and jetties are.

Yea there was a profession speaking at the TedX the other day that talked about a few things that would help.

They actually have a program to pump wastewater to the marsh outside of nola, and then make an effort to plant cypress trees in the areas that they used to be in.

The problem with the water is that it gets a higher N count when diversion/wastewater is present due to nutrients.
Nutria like the Nitrogen high plants more than not and they destroy and eat all the young plants, etc.

They are using pvc devices to protect sapling trees

This is who spoke LINK
The page on the project and some helpful links LINK

and the page for the Coalition to Restore Coastal Louisiana LINK (they have links to articles supporting what some in this thread have been talking about as well.

That's right. Important to know what the sediment load of the river was when most of the delta was built vs what it is now vs what it will be.

Salt water marshes have substantial root systems that resist erosion and storm surge damage. Caernavon proved that freshwater vegetation is mostly floatant and easily washed away.

re: Planned freshwater diversions will doom LA salt fishing


well freshwater alone would only bring floating veg, but with sediments it would rebuild the area into land. Then with replaced Cypress marsh, it would return to (i think) the bottomland forest that it used to be, then the saltwater plants would just be in a new location as the mass advances.

But this all depends on sediments. I would like to read more on the diversions that do incorporate more sediments.

Id rather catch bass instead of specs in these places and be able to show the grandkids where i grew up instead of showing them water saying "the house was out there somewhere

re: Planned freshwater diversions will doom LA salt fishing


The last discussion went like this:

Freshwater diversion =/= sediment diversion
Freshwater marsh =/= saltwater marsh


That basically sums it up. Until you get the sediment diverted, not much is gonna happen

re: Planned freshwater diversions will doom LA salt fishing


I guess that is where the wastewater pumping project got interesting.

The title of the talk was "take a few good shits on the levees of Louisiana"

Yea WWTP pumping is a viable locall option
