What in the frick is this bullshite?

Freshwater diversions are not killing the marsh. Oyster fishermen always complain but in reality a lot of them are fishing areas that historically were freshwater but due to salt-water intrusion (thanks to the O&G canals ironically) are now brackish enough to support oysters. If we blow more freshwater into the marsh, then they are correct that the oysters may never return to their current locations - but they will start showing up in areas that they currently don't thrive in.
Yes.
They oyster guys and groups like "save louisiana coalition" (
) are just trying to impede steps that can actually help the coast. It really pisses me off. AND now I'm angry. Damnit.

The salinity is lower due to the wall at MRGO and the weir at rigolets. Post Katrina storm surge deterants don't allow the salinity to flow in like before on strong S/SE winds and tides. You get a lot more freshwater, which means more algae and less O2. The salinity slowed the blooms. You still catch them, but it's not ideal like in the drought of late 90s early 2000s when it was a blue crab and mule trout heaven.

Not bullshite, natural oil seepage happens all over the globe. Go to any beach in southern Cali and chances are your going to find some tarballs.

Agree with whole post. We're doing fate and transpo of BP crude and the coast is extremely good at getting rid of it

We see more green trout, and lakerunners, in the Chef Pass area than before. The crabbers have said that they catch less, but there are plenty in summertime. I won't complain about more freshwater in the area.

My aunt lives in Venetian isles and I've wanted to do some freshwater fishing. Can you send me in a general direction?
Also if the trout get replaced with green trout that ain't a bad thing IMO

While I completely agree something is different over the last two years with fish and crabs over the last two years, anyone who says the lake no longer has big trout hasn't fished out there recently or doesn't know how to fish the lake.
This past fall winter run was one of the BEST runs for big trout I have seen in quite a few years. I had four trips where we limited and had trouble limiting because the fish were too big and we threw them back trying to catch better eating ones. I have pictures to prove it if someone doesn't believe me, but we caught 6 lb or better trout in the lake on every trip last fall except one.

But the vast majority didn't wash onshore.
Much more of it hit the shore in concentrated locations than with natural seepage and a vast amount of it also became entrained in the water column. We do not yet know the lasting effects (if any) to the Gulf ecosystem in general, much less on the marsh system.
Natural seeps occur in numerous locations over the year, slowly and are spread out. The majority of oil from natural seeps reaches the surface and is not suspended. Natural seeps are not a constant stream discharging in a single location.
The Macondo well discharged multiples of all the oil discharged by natural seeps in the Gulf combined on a per day basis into one location. To believe that the spill was comparable to natural seepage in terms of stress effects on the Gulf ecosystem is naive. The amount of oil released in such a short time in a constant fashion in a concentrated area is simply not comparable.
It is possible that the ecosystem will adapt and endure without any significant long term issues, but you cannot assume that will happen simply because the gulf has over a long period of time adapated to handle natural seeps.

It's oil. It's a natural substance the marshes are used to handling.
The marsh has adapted to handle oil at a certain rate. The immediate short term impacts due to fouling is one issue that you mentioned. But what we do not have a firm grasp on is the long term chemical effects of such a significant increase of the level of hydrocarbons in the marsh soil on the root systems. It will depend on the type of marsh, the composition of the soil, the the makeup of the oil, the location,...etc. It's a complicated thing and we do not have an answer at this point.
Salt is natural and tolerated by marsh too, but if you significantly increase the salinity of water marshes will begin to die off.
DISCLAIMER - I did not read the website and am not arguing that they are correct. I am no eco-nut, I just think it is wrong to assume everything is fine and that there will be no lasting impacts when we clearly do not have enough data to determine that at this point.

Last year in the lake was ok at best. The speckled trout fishery lake has been on a steady decline for the last 6 years. The 2009 spring was probably the best spring since the early 2000s. I have pictures of a five fish stringer from that year weighing 33.8lbs. Thankfully though, speckled trout fishing in the lake is and always has been cyclical. Those three years at the turn of the century were absolutely insane, and you can look at the top 10 fish in the state for proof. The old guys I fish with will say the same about the late 80s/early 90s. I'm talking about flipping 7-8lb trout in the boat insane. As someone posted earlier, it's more than just nostalgia when they talk about it. You can see that things really used to be different. Things are different now, and I'll stay off my soapbox of speculation as to what's really changing things, but to say the lake was the best it's been in awhile last year just isn't true. We caught good numbers of big fish, but those were sporadic and random. The trout have been off their normal lake patterns for a few years now. That being said, though I don't know that it'll ever get back to the days of 8lb fish being normal, I do expect it to come back here shortly. Possibly this year if they leave the spillway closed.

And you don't think the decline of big trout has anything to do with the targeting of big female breeder trout?
It's crazy that we don't have a slot limit on trout. Combine that with CCA putting a bounty on our breeder trout and you end up with people killing every 6lb spec they catch so they can post hero shots on facespace.

Of course I do, but I've fished the lake and trout plenty long enough to know that's only one small piece of a huge puzzle.

Yeah, before the K-Paul decimation, there were hardly any crabs around. we should reopen them to commercial fishing.

It depends on what you want to manage for, do you want to manage for "trophy trout" (similar to how lakes manage for lunker bass) or do you just want to ensure a healthy dynamic stock that can last?

I will say this again about trout in the lake anyone that thinks the lake is on a full decline DID NOT fish it last fall/winter. It was the best it's been in 8-10 years my boat caught 12 fish over 6 lbs that were all released. It was REALLY good last fall.
Posted on 3/20/15 at 1:05 pm to Da Hammer
The lake isn't in a full decline. I don't disagree at all, but last year really wasn't good. It was just better than the three years prior. 12 fish over 6 pounds in a fall on the lake isn't "good" for the lake by any means. Compared to the last three-four years maybe, but not compared to the standard I hold for Lake P.

MRGO was a highway to and from the gulf for a lot of sea life,so yeah things are not going to be as they were.

after attending the GOM oil spill conference in houston this year, I'm convinced that the vast majority of "affected" area is doing fine. Of course there are worse spots (my research) but our ecosystem is remarkably resilient.

You must fish it better than me so we need to fish. I've fished it pretty consistently for about 20 years, last fall was as good a run as I have seen out there. It was like a normal year IMO it was hard to catch a trout under 18". That is the way the lake is supposed to be.
Still doesn't explain the lack of trout 12-16" and lack of crabs though. Something is certainly amiss in SELA.
