Wiers not opening this year

[Duck Butter]

and aerials from 1998 and 2008

["W"]

Those picks are not really true... you posted a aerial right after Rita which flatten all the marsh grass with a 25ft surge


That marsh has came back and grass is growing back fuller than ever in some areas

OK, then why does this grass coming back not show up in 2008 pics? Look at that east bank of Calcasieu Lake in the 2008 photo, look at that lost marsh, I can post a Google Earth 2013 pic and you can see it there too

I sent you a link where you can do this yourself and click the layers on and off and see different years flash right before your eyes, you don't have to believe me

Click on this link then download that map on the right, it will show you every single bit of data regarding coastal land loss
http://pubs.usgs.gov/sim/3164/

Check out this map and remember that red is bad

and go back and look at the map MG posted, its not rocket surgery

All that red is what has already been lost i.e it ain't there anymore

So the weirs are not helping??? Right?? West side looks better than East side with weirs?

Whats up with that??

Wiers are slowing it down, its all going to be gone one day at this rate

I disagree, the land loss (red) on the west side is much more pronounced than the east side, it could be quantified as well and I am sure it is somewhere but its pretty clear to me

per MGs map and you can look at that site its in .pdf format and I can't copy the pics for some reason, but maybe MG can post a pic for the east side of the lake for comparison

and here's a funny pic I just saw in My Pictures file

There are several factors in play since the dredging of the ship channel that make the marshes on the SE area of Big Lake more susceptible to saltwater intrusion than the marshes on the S side of West Cove.

Probably the biggest factor is the fact that the dredging has given salt water a wide open path to the SE corner of Big Lake, but has added a significant barrier to the path to West Cove. Note that now there is both the 40 ft deep 400 ft wide ship channel and the original Calcasieu river channel leading bringing salt water into the SE part of Big Lake. The open part of the ship channel into the SE part of Big Lake is several miles long. In contrast, the dredged material was used to build up a barrier between the ship channel and West Cove, and there are only a couple openings a few hundred yards wide for the salt water from the ship channel to flow into West Cove. Recent enhancements (the three new weirs) to the water control structures in West Cove were more needed to improve flow of freshwater out of the marshes than to reduce flow of salt water back into the marshes surrounding West Cove.

The SE part of Big Lake is also subject to greater wave action and larger wind driven tidal flows owing to the greater fetch on the east side of the lake by comparison with West Cove. See:

MG, that red is WRONG, that land is THERE! These maps are all LIES, LIES I tell you

blame it on Will Drost!

from http://media.nola.com/environment/ot...ap_5-24-11.pdf

Reds, pinks, and purples are all land loss. Pinks and purples are post 2000. Reds are earlier.

Based off that map the marsh south of west cove (with no weir system) a so called natural marsh has suffered way less land loss than the east side of the lake controlled by a weir system. Data was estimated until 2010, never get in the way of Mother Nature!

100% right

But wait they will tell u the weirs are making the east side marsh a super marsh


And we are having almost 1.7ft falling tide every afternoon and trapping mother natures habitat from being natural state

I have no dog in this fight, but them maps are not real right, been having a camp in the red part, for 5 year's and the marsh is healthy and nice. No all the trees have not come back from the storms but they growing. Also gator hunt Sabine ref, for3 years and there's way more marsh then there was when I was inthere in 05 , , there are weirs on the west side of biglake and they just fixed last Sep. Don't know if they ever open or close the now. But the first of Sep. I will take a ton of pics and post of the marsh. Are the wiers helping or hurting??? The fishing?? Maybe maybe not, are they helping the marsh??? From what I have seen some places yes others not at all. Just my 2 cents

No way...cant be...duck BUTTer and Smalls know every square inch of our estuary

Ill agree with u dub. U live down there practically. From what I see from a non avid bl expert(jk) those pics aren't true. There's a lot of marsh that those maps say aren't there that really are. But some of the pics show land where there isn't much to speak of as well. How do they judge this? Serious ques. From a chopper? I know the arial shots are from the air but the marked maps are they judging land loss from the air or do they survey on airboats bc that could be the deception I guess

Man I'm sick and tired of you trying to trash me. I don't know what I did to piss you off, but get over it. I do what I have to do to make a living, I don't talk crap about what you do. Don't trash what I do.

W, I do field surveys all the time and before I step foot out on the property I look at aerial photos, historic maps, topo maps, and soil maps. You can look at a soil map and pretty much know whats going to be there before you step foot onto the property. Just by looking at a soils map I can tell you the plants that will be there and with the plants come the animals. You then go and 'ground truth' the area to document what is out there. Its not rocket surgery.

One of those maps shows land across the ship channel in 1992..CMON man

Where do you see that?
