Rez Faces Salvinia Threat

The Pearl River Valley Water Supply District issued the following statement.

Giant salvinia, an aggressive non-native aquatic plant, has been found in the Pelahatchie Bay area of Barnett Reservoir near Jackson, the Pearl River Valley Water Supply District announced.

Efforts to eradicate giant salvinia will require multiple applications of multiple herbicides, which the Mississippi Department of Wildlife, Fisheries, and Parks (MDWFP) said will also have an unfortunate impact on important native vegetation, such as lotus (lily pads).

MDWFP first discovered giant salvinia in a small isolated patch along the Bay’s north shore earlier this summer, but recently located more of the problematic plant in pockets spread through a five-acre area. Efforts to contain its spread have begun, and the MDWFP will soon begin an aggressive spraying campaign to eradicate it.


Giant salvinia, an aquatic fern, is native to Brazil and was first found in the U.S. in South Carolina in 1995. MDWFP biologists say it is one of this country’s most dreaded invasive plants because of its rapid growth potential and the difficulty of eradication. Research has found that it is capable of doubling its biomass in 36 hours in optimal conditions, which include warm, still waters.

If unchecked, the plant can take over an entire lake cove in a matter of weeks with mats up to three feet thick, choking out all aquatic life and making boating, swimming or fishing impossible in affected areas.

This is the second time giant salvinia has been found in Barnett Reservoir. In 2013, a biologist recognized a small patch in the harbor at the Goshen Springs Boat Ramp on Mississippi Highway 43. It was quickly eradicated and removed from the water.

Since it is believed the plant is introduced to new waters primarily by boaters, PRVWSD and MDWFP officials say it is important that anglers and boaters clean, drain, and dry their boating equipment after each use to limit the spread of invasive species, and to report all non-native aquatic species they encounter to MDWFP Fisheries Bureau.

It won’t be long before this takes over Lake Caroline, Reunion, lake cavalier, and any other lake in the area that allows outboards to run. People are too lazy/careless to take the necessary precautions to prevent this from spreading.

Whahaha, my evil plan is working!

What about people who eat fish from the Reservoir and below on the river? What kind of herbicides?

Flying Wild Hogs Spotted said...

Meanwhile; flying carp have now been spotted in Lake Washington, the only oxbow to not have experienced those invasive fish to date. And wild hogs continue to take over all hunting areas along the Mississippi River.

As always, MDWFP is asleep at the wheel and does nothing pro-active. Too busy planning retreats and hunting expeditions.

It's high time the governor appointed a commission to meet quarterly in Jackson to study these issues.

12:58, an engine being an outboard has nothing to do with it. Plant matter more often than not attaches itself to the trailers of any boat or watercraft ie:JetFlea.

Just sayin.........

The Government should look to Louisiana for learning how to deal with this. They’ve been fighting it for years. More or less, herbicides only make it meaner and don’t kill it.

There is a guy in Bossier City that modifies his boat to cut and bag it insitu. It seemed the best option.

It was the non-professional Game and Fish commissioners who created the hog problem in 1972 by introducing the Russian Boars into our woods against the advice of Mr. Bill Turcotte, He said then that we do not need any exotics

Any hog Russian, domestic or otherwise, left to their own devices or released in to the wild will become a feral nuisance in a matter of months.

Probably came from some drunk TSUN frat boy driving in Daddy's boat and drowning his sorrows over that awful defensive effort on Saturday.

We ain't obsessed with y'all!

1972---Hmmm...Let's think about this...Democrats ruled the state. Surely you can't blame Republicans for this!

2:48, just what the hell do you think MWFP or anybody else could do - as you call it - "proactive" about this issue? Proactive - stop it before it gets here.


Hmmm. Would you propose that they should be at every boat ramp between Burnside and the spillway making sure that each and every boat, trailer, and all fishing equipment be sterilized before they entered the waters? Also, putting a net over the entire area so that birds couldn't enter the water after having been in other water where this crap exists?

Seems to me that they are at least acting now that it has gotten into the res, just as they did last time it was found. But as far as I can determine, there is not a 'proactive' solution that would ensure that it could not enter the waters.

But, am waiting with baited breath to hear your suggestion, since you're butt-hurt over not being hired by MWFP as a game warden or some such reasoning. Please give us all your proactive suggestions so that we can protect our private and neighborhood waters.

4:23,It was Members of the Mississippian Party that continues to run this state. National party tags are something that are added and taken away at will in this state ! I do not know of one elected official in Rankin County that is a true Republican.

Can you imagine being so unemployed that you give two shits about "muh water-zudzu"

As with Israeli Carp (which spawned flying carp) the State Game and Fish Commission, as it was called in the sixties, not only allowed, but promoted and advocated (and in some cases sponsored) the importation of these carp into our waters to 'take care of' vegetation that was beginning to take over Delta ponds and lakes. And the rest is history. Same with their importation of hogs.

There's your 'pro-active', 5:21. The only agency more incompetent than MDPS/MHP.

the PRVWSD and the MSDWFP are such bozos they could not organize a 1 car funeral. invasive plants, animals and fish have been destroying the ecosystem in this state for the past 40 years and these two administrative agencies are helpless to do anything other than cash their bi weekly paychecks. as far a PRVWSD goes, they got employees who cant even brush their teeth. just check out that rotten tooth redneck reservoir cop from oregon. by the way 4:23pm, the people that ran the democratic party back in the 70s now have a new name........ they call themselves republicans. you are not aware of that because back then , assuming you were even born then, you were busy crapping in your hands and rubbing it in your hair.

I flew out of the Charleston airport 2 days ago to come home early. I usually spend 8 weeks there each summer. I had to board up beach house and sandbag the areas around doors. Hopefully it will miss Charleston area and people will be safe. Back in NE Jackson with hopes for the best. I just rebuilt part of beach house 3 years ago with smaller previous storm. This is a monster.

"What about people who eat fish from the Reservoir and below on the river? What kind of herbicides?"

You should only be eating fish from the reservoir-north of 43, not those below the dam or from the Pelahatchie Bay area. That way you'll only be eating fish that consumed runoff ag chemicals from Madison, Leake, Scott, Attala, Choctaw, Winston and Webster Counties.

Otherwise, your question is reminiscent of the 'pee in the shallow end' theory of pool safety.

Trollfest '09

Trollfest '07 was such a success that Jackson Jambalaya will once again host Trollfest '09. Catch this great event which will leave NE Jackson & Fondren in flames. Othor Cain and his band, The Black Power Structure headline the night while Sonjay Poontang returns for an encore performance. Former Frank Melton bodyguard Marcus Wright makes his premier appearance at Trollfest singing "I'm a Sweet Transvestite" from "The Rocky Horror Picture Show." Kamikaze will sing his new hit, “How I sold out to da Man.” Robbie Bell again performs: “Mamas, don't let your babies grow up to be Bells” and “Any friend of Ed Peters is a friend of mine”. After the show, Ms. Bell will autograph copies of her mug shot photos. In a salute to “Dancing with the Stars”, Ms. Bell and Hinds County District Attorney Robert Smith will dance the Wango Tango.

Wrestling returns, except this time it will be a Battle Royal with Othor Cain, Ben Allen, Kim Wade, Haley Fisackerly, Alan Lange, and “Big Cat” Donna Ladd all in the ring at the same time. The Battle Royal will be in a steel cage, no time limit, no referee, and the losers must leave town. Marshand Crisler will be the honorary referee (as it gives him a title without actually having to do anything).


Meet KIM Waaaaaade at the Entergy Tent. For five pesos, Kim will sell you a chance to win a deed to a crack house on Ridgeway Street stuffed in the Howard Industries pinata. Don't worry if the pinata is beaten to shreds, as Mr. Wade has Jose, Emmanuel, and Carlos, all illegal immigrants, available as replacements for the it. Upon leaving the Entergy tent, fig leaves will be available in case Entergy literally takes everything you have as part of its Trollfest ticket price adjustment charge.

Donna Ladd of The Jackson Free Press will give several classes on learning how to write. Smearing, writing without factchecking, and reporting only one side of a story will be covered. A donation to pay their taxes will be accepted and she will be signing copies of their former federal tax liens. Ms. Ladd will give a dramatic reading of her two award-winning essays (They received The Jackson Free Press "Best Of" awards.) "Why everything is always about me" and "Why I cover murders better than anyone else in Jackson".

In the spirit of helping those who are less fortunate, Trollfest '09 adopts a cause for which a portion of the proceeds and donations will be donated: Keeping Frank Melton in his home. The “Keep Frank Melton From Being Homeless” booth will sell chances for five dollars to pin the tail on the jackass. John Reeves has graciously volunteered to be the jackass for this honorable excursion into saving Frank's ass. What's an ass between two friends after all? If Mr. Reeves is unable to um, perform, Speaker Billy McCoy has also volunteered as when the word “jackass” was mentioned he immediately ran as fast as he could to sign up.


In order to help clean up the legal profession, Adam Kilgore of the Mississippi Bar will be giving away free, round-trip plane tickets to the North Pole where they keep their bar complaint forms (which are NOT available online). If you don't want to go to the North Pole, you can enjoy Brant Brantley's (of the Mississippi Commission on Judicial Performance) free guided tours of the quicksand field over by High Street where all complaints against judges disappear. If for some reason you are unable to control yourself, never fear; Judge Houston Patton will operate his jail where no lawyers are needed or allowed as you just sit there for minutes... hours.... months...years until he decides he is tired of you sitting in his jail. Do not think Judge Patton is a bad judge however as he plans to serve free Mad Dog 20/20 to all inmates.

Trollfest '09 is a pet-friendly event as well. Feel free to bring your dog with you and do not worry if your pet gets hungry, as employees of the Jackson Zoo will be on hand to provide some of their animals as food when it gets to be feeding time for your little loved one.

Relax at the Fox News Tent. Since there are only three blonde reporters in Jackson (being blonde is a requirement for working at Fox News), Megan and Kathryn from WAPT and Wendy from WLBT will be on loan to Fox. To gain admittance to the VIP section, bring either your Republican Party ID card or a Rebel Flag. Bringing both and a torn-up Obama yard sign will entitle you to free drinks served by Megan, Wendy, and Kathryn. Get your tickets now. Since this is an event for trolls, no ID is required. Just bring the hate. Bring the family, Trollfest '09 is for EVERYONE!!!

This is definitely a Beaver production.
