LDWF to drawdown Bistineau May 1
Posted on 4/13/17 at 7:55 am

The Louisiana Department of Wildlife and Fisheries has scheduled a drawdown of Lake Bistineau in Webster, Bossier and Bienville parishes for giant salvinia control, organic reduction and fish habitat improvement. The water control structure is scheduled to open on May 1.
Giant salvinia is growing rapidly. Despite LDWF contractors treating over 5,000 acres since Feb. 20, significant coverage is still present. The department estimates the plant covers 3,349 acres of the lake based on an aerial survey conducted on March 23.
quote:
The drawdown is designed to reduce the further expansion of salvinia as summertime temperatures promote maximum growth. Spray efforts are ongoing in areas of the lake that will not dewater during the drawdown. Intensive herbicide applications will continue during the drawdown in an effort to further reduce salvinia on the lake.
The lake should dewater at a rate of 4 to 6 inches per day and will be lowered to a maximum drawdown level of 8 feet below normal pool stage. The Lake Bistineau control gates are scheduled for closure on Nov. 30, to allow the lake to refill for winter and early-spring recreational activities.
quote:
During the drawdown, an estimated 10,000 acres of water will remain in the lake. Boaters can access the lake from the following public boat launches: Port of Bistineau Launch, Bossier Public Launch, Grice’s and Bayou Dorcheat Public Launch. Boaters are advised to use caution during the low water period, as boat lanes will not provide normal clearance of underwater obstructions.
Do they normally do this twice a year? I thought it was only done in the fall.

They need to give it up with the drawdowns.
Of course, last drawdown was cut short by the rain, the lake filled itself up very early.
They are going to have to put money into this lake or it will be gone. The 2 spray boats dont work, the constant drawdowns dont work.

Nothing proposed so far has worked. They need to get outside of the box. I'm thinking complete drawn down, dry out, herbicide and keep it dry for 1+ year. This up and down and the residents get a month or two before it chokes up is for the birds.

It is as bad right now as it has ever been in April. My dad has been going to the meetings and the level on competency trying to figure out the problem is extremely low. They decided to drop the lake May 1 with no plans on when to raise it, no plans to add more spray boats and no plans with how to kill the plant in the long term.
There needs to be a large amount of money poured into this issue or there will be several more lakes killed in LA. There are some folks in Southern Miss that have a fungus developed that kills it but currently does not grow fast enough to keep up. As someone who has been going to Bistineau for my whole life, this is extremely sad.

Until they put the money and effort into developing cold tolerant salvania weevils, this is a fight they'll never win.

Agree. The drawdowns and herbicide do nothing for the seed buried in the mud. It will all grow back as soon as water rises. Something a lot more intensive needs to happen.

Same. One of the few lakes around here that I can actually catch fish.
I had/have an opportunity to get a nice place on the water for a steal but there is no way that I can comfortably do that with how unstable the lake is.
ETA: I know Ryan Gatti is on board with getting the lake back in shape but if he has no backing from state or fed then his "wants" are as just as good as mine.
Hell last drawdown the residents were out there clearing the log jam at the dam by hand and homemade grappling hook because they could not get any gov help.

My family has had property on the lake for 60+ years and my folks bought their new place almost two years ago now on the north side. It sucks when you look out to the channel to literally see NO water in any direction.

My next door neighbor bought a camp on it last year for a steal. But as you pointed out, no guarantee the lake will ever shake back.
People are selling and getting out of there.

Same to you brother. Just treading water over here, trying to find where my kids hid my sanity at.

I really want to rent that big cabin or house on the disc golf course. Bring my yak and discs and beers.

It's a shame, I think there will be a remedy some day though. I just hope it doesn't spread to the north eastern portion of the state (Concordia, St. John) in the mean time.

I'm going to ask a dumb question here..... Do carp not eat that stuff? I know there are types of aquatic vegetation they will and won't eat and didn't know about the giant salvania?
Posted on 4/13/17 at 9:10 am to ElDawgHawg
Apparently the salvinia contains a metabolic toxin, and if a carp eats too much of it they will die
ETA:
Then you have the tree cutting group. I understand that they see the lack of trees means less space for the salvinia to get stuck and multiply, but a few thousand acres of cut trees does not stop the actual salvinia.

Someone needs to find a genetic remedy and that will happen one day, hopefully soon. A fungus or bacteria will be developed that will kill it. Hell, low salinity water will kill it, but Bistineau cycles water every 60 days or something and they would not be able to keep the salt content at the right level without killing everything else.

The coldish winter we had a few yrs back helped some didn't it? I recall Rick Rowe doing a piece about it helping. Maybe that's the answer - cold. Salvinia probably never quit growing this past winter.

A HARD freeze would do wonders. Like early 80's, freeze the Red River cold. If the lake was down and we had a freeze like that, it would help tremendously. Since we can't count on that at all, every other possible solution has to be tried. And you're right, it never quit growing over this last winter. Only had a hand full of nights below 32.

La Tech was working on a bioherbicide a few years ago but I have not heard anything else on it.

One thing is for sure if they keep doing the same thing over and over they will keep getting the same results. Which leads me to believe that someone either in LDWF or State Government is making money on the spraying via kickbacks or campaign contributions.

LSU AgCenter Salvinia Research Article 4-12-17
Edit: Not much in the article, but efforts are still underway at least.
