WLOX Story

Essentially, Mississippi coastal mayors are blaming spillway opening on too much fresh water in the Mississippi Sound causing dead dolphins, crab harvest being down, and no oyster production this year.

I am sorry but Mother Nature can be a beast.

I saw on the story’s Facebook link the same old saw about how this would be the new normal once more river diversions open up.

While I will agree about why the water is now too fresh, but I will argue the opponents of diversions that the current perspective of the Mississippi River estuary where it is more salty and say that is not how that estuary operates.

Natural, if the Mississippi River were able to flow freely from its current channel and in its current high water state, it would be pushing fresh water EVERYWHERE.

To the oyster fishermen and crabbers, we have artificially created a saltwater water environment that goes all the way to Chalmette and even in Lake Ponchatrain.

While some are blaming the spillway opening, some are also realizing that the Pearl River too is adding to the fresh water in the Sound.

So what are we to do. Do we just keep all this fresh water away from the Gulf coast so Mississippi can see dolphins all the time?

This is only a temporary issue, once the river level gets back to normal salinity levels will get back to normal and the dolphins will return.

On the upside, all the nutrients in the sediment will make bigger crabs, etc over the next few years.

I see nature at work, here. It’s either gonna come out where it currently is or at the Atchafalaya. Either way, there would be a massive dead zone somewhere in the northern Gulf.

If they don't like the spillway being opened then we can just blow several holes in the levee up river on the east side and flood North Mississippi

It will be interesting to see how dredging the Mississippi an extra 5 feet deeper will impact these events.

Actually Mississippi is higher so it would flood on the Louisiana/arkansas side

I don’t think there are enough dredges in the country to make a difference

Animals that live in water aren’t wildlife.

If they were LDFW would only be LDW.

Back when private companies were allowed to dredge the river and sell gravel they didnt have the build up. At least not at the current rate.

The Jones Act America’s dependence on the seas remains integral to its economic health and survival as a nation. Similarly, because of the vastness of the nation, the expansive network of rivers, lakes, and canals is critical to the efficient transportation of natural resources, food, and manufactured goods from state to state and ultimately to market. Because of the importance of the merchant marine and the critical role that coastwise and inland waterway transportation plays in its economy, America has always made sound decisions about protecting the integrity of this system along with the vitality of our waterways. Thus, the Jones Act, titled after its sponsor Senator Wesley R. Jones, from Washington State, was passed as part of the Merchant Marine Act of 1920.

This federal legislation imposes four primary requirements on vessels carrying goods between U.S. ports.

The vessels must be:
owned by U.S. companies that are controlled by U.S. citizens with at least 75 percent U.S. percent ownership;
at least 75 percent crewed by U.S. citizens;
built (or rebuilt) in the United States;
and registered in the United States.


Every dredger operating within the U.S. is subject to the Jones Act.

This has led to a closed market, not subject to foreign competition, where some 300 dredging companies operate, widely scattered, with an outdated fleet, mainly small equipment (largest trailer dredger is "Wheeler", operated by the U.S.A.C.E., with a capacity of 8000 m3).

Research and development is mainly focused on environmental and geotechnical issues, little on upgrading efficienty of dredging equipment.

The US is so behind the Netherlands in dredging it’s stupid. But of course we can’t hire foreign dredges even if we wanted to

What spillways were opened to the east of the Mississippi? Does the Bonne Carrie send fresh water to the east?

You mean to tell me for profit companies are more effective and efficient that government agencies?

Yes. All that freshwater flowing into Lake P from the BC spillway eventually makes its way into Lake Borgne and along the Mississippi coast. With as long as the spillway had been open this year so far, makes a pretty big impact on salinity

People complain when the Bonnet Care is opened saying Lake P fishing will go to shite. NOPE just the trout in the usual areas. Red fish and bass are there all day to be had. Then before you know it, the lake clears up and the same people are bitching that they never catch trout in the Rigoletts. Sound to me they can't fish
