Freezing Weather and Giant Salvinia

fishin couillon · January 03, 2018, 05:00:17 PM

So with these few weeks of good cold freezing weather, do yall think it will help with the GS issues they have up on Black Lake, Bistineau and where ever its at in our part of the state???

The freezing temps are a bonus but honestly we've only had about 10 night below freezing. The last couple days that didn't get above freezing are awesome but we'd need a couple months to really help.

A couple years ago we had a good freeze. We were on Caddo and the lake temp was 38 degrees. It had just snowed a couple inches and we hadn't seen above freezing temps for two days. We found Salvinia floating in logs, hollowed out stumps and along shore that was green and not effected. I think in order for Mother Nature to kill it, she's going to have to freeze the lakes over and the ground around the lakes as well.

Not knocking it and it's bound to help some but we'd need a lot more of it.

might be kind of like it was for wheat back when I lived on the farm. freezing, below freezing temps (air) don't indicate actual soil, ground temps and that 'area' just above ground that's not really that low (buffer zone).

now if that lake ices up, bet that's a way different deal.

Our problem with salvania is that a beaver could have it in the hut and when the lake floods it's back. It doubles every 7 days. Doesn't sound bad at first but add it up once you get to just one acre. In just 4 weeks you are at 8 acres, the following week you're at 16 then 32... If we don't get every leaf, root and seed, it comes back when the water reaches about 70, which our water is in the productive zone for salvinia about 9 months a year.

This cold were getting is going to help, if the state continues spraying we have a chance that maybe by next fall the lakes won't be unusable as they were this fall.

according to this, the cold has little impact.

Good find

Thanks for sharing.

I believe everything in the article but have been on Caddo a few time in the past couple of weeks and most of the back water in the trees has ice in it......I am hoping that we see a big difference this year than last. I don't think that it will kill it all but some damage has been done!!!! We need a 1985 winter!!!!!

Steven Flanagan · January 19, 2018, 02:18:07 PM

If this winter does not knock out 50%+ of the salvania, then we have no hope.

Mike Cork · January 19, 2018, 03:17:09 PM

between the spraying this past fall and this cold weather I haven't see a speck of it in Cross Lake. But the lake is so low that you can't get very far back into the woods and it could be piled up in there.

Steven Flanagan · January 19, 2018, 06:55:27 PM

I would think this low water is a added benefit to the freeze we just had. now seems like a good time to be spraying. hit it while its not thrieving

Elwood · January 19, 2018, 08:32:36 PM

I hope that mother nature takes it out.....I know the guys are spraying but that is their source of income....I do not see it eradicated by spraying.

Steven Flanagan · January 19, 2018, 09:55:35 PM

maybe i dont looki in the right place, but i never see any results when they spray. either they dont spray correctly, the chemical doesnt work, or they arent using the proper chemicals in efforts to save money. $:-\$ $:-\$ $:-\$ $:-\$ $:-\$ $:-\$

FishinSteelersFan · January 19, 2018, 10:03:10 PM

The freeze we had about 4 years ago killed more than any of the spraying did, hopefully this freeze will kill it back again.

Steven Flanagan · January 22, 2018, 09:11:35 AM

whomever is in charge of the spraying should be fired or strongly reviewed. it appears like a waste of money.

ice HAS to help, but without complete eradication, it's just temporary.

wondering if the game/parks folks are actively spraying, pursuing eradication while the GS is at it's lowest resistance?

Mike Cork · January 25, 2018, 10:25:03 AM

Spraying now would obviously create the best results. However I don't see any happening at Cross, of which if you do get into the woods you see it. I also noticed it in the bayous around cross. The first major rain will flush it out into the lake. Unfortunately these bayous are unreachable because of the low water and drained lakes. I pretty sure even a 4 wheeler will sink to the handle bars in the muck.

RustyJ · February 20, 2018, 09:48:32 PM

I've been on Bistineau the last couple of days and there is plenty of green salvinia. It looks like the salvinia that was out floating in the main lake/open areas survived well. The salvinia that was near the banks seems to be less green, if that makes sense.

By the way, the lake is full.....lol

Mike Cork · February 21, 2018, 07:43:47 AM

I'll bet after this week it will be completely full. Bossier parish is already calling for river flooding, so that means Bodcau is going to be a raging ocean of water before long.

I've seen green stuff on Caddo, Black Lake Campti, and Black Bayou Hosston. It's going to take a cold that freezes the red river over before it kills this stuff.
