re: LDWF to drawdown Bistineau May 1

We have the same problem here at Iatt lake draining every year is not helping. I heard they are going to cut some trees down this summer when they drain it. I'm guessing they are trying to free up some space for it to move around like yall are saying.

Again, the answer is the weevil. This is a lake in Australia that was saved by weevil inundation.

I grew up on this lake and it is a shame what has happened to it. I have seen one proposal advocate drawing the lake down for 10 years or more to get the salvinia under control. They would probably have to remove the spillway to allow it to draw down far enough to do any good. I haven't had my boat on the lake in the last 8 years because of it.

I think you are correct. Obviously what we have been doing isn't working. Take it down to just the bayou until science comes up with a way to kill it. That way you keep it from being spread. I have noticed that it seems to die once it flushes into the river.

Where did salvania come from? I don't remember ever seeing it until 10-15 years ago and then boom, it's a disaster.

Just my opinion on the whole situation:
The pH levels and "stagnant" waters of lake bistineau in addition to the in heavily tree areas create an ideal environment for salvinia to grow. The Red River and Loggy Bayou have "moving" water and thus the reason the plant doesn't grow nearly as well in these river environments.
It's sad to see bistineau in such a bad place because I know over a dozen people that have nice camps out there that aren't able to use it. Someone in my family just built a boat dock this past winter and said "well, I'll have one hell of an expensive tree house this summer!"
I think there is much more the LDWF Agents can do up here, but it would cause much more work on them.
First, they need to be effective in what they are spraying. What I mean by this is the spray boats go into and area "spray around" and then leave... if the wind changes direction, that salvinia floats out and is dipersed into another pocket on the lake.. then the next day, the agents see this other pocket full (because it is still green and hasn't died yet).. the agents then spray this area which is sometime duplicating efforts.. most importantly though, the agents should boom off severe areas and spray the salvinia inside of the boomed off area; come back in a couple of days and then again spray the areas they may have missed (by looking at the salvinia that isn't brown).
Secondly, I think a massive weevil program has to be introduced into the lake's northern end (where the large part of thick trees are). As stated previously, the close proximity of the cypress trees prevent the agents from spraying in that area. The only way salvinia will ever get off the lake is by eliminating the massive amount "caught" in the thick trees..
I have several other ideas, but these are my thoughts on the first two logical steps in getting the salvinia back under control for the amount of money they have spent here recently.

To where?

We have a levee at the back of the property that drains into the swamp/ponchatoula creek. So we broke the levee and sprayed every 2 weeks. LSU came out and tried the weevils, they would die in the winter.

Does this not spread it? seriously curious, never dealt with this stuff.
coontail is my mortal enemy.

From Wikipedia:
The plant originated in southeast Brazil and was exported as part of the pet industry to be used in aquaria and garden ponds. From there, it escaped or was deliberately released into the wild.

Last I heard there was some very promising research out of Baylor 2 years ago, I wonder what happened?

Damn, hogs and salvania. If people would just leave well enough alone.

If any of it made it to the creek it would have been very minimal, and it already has salvinia in there.

Secretary Montoucet will be in attendance for the upcoming Lake Bistineau public meeting to discuss efforts to control giant salvinia on the lake. The meeting will be held next Thursday, June 15 at our Region 1 office in Minden at 6:30 p.m.

I would be interested in hearing what their long term plan is, but im not driving to Minden. 
Posted on 6/6/17 at 9:27 am to SportTiger1
I actually see nothing but gloom and doom. It's going to be everywhere eventually, and we can't spray everywhere. Maybe it's not so bad that my son hates fishing.

Interesting. Leaving it up to the citizens to release the weevils...

Hopefully everybody just takes them to Caddo.

Great minds think alike.
