WEIRS
Everyone starts catching fish on Calcasieu. What's the deal? Was it the weirs or not?
|
We all been on Sabine !! Where you been??
When you left for Toledo Bend all us Guides raped Sabine !! And Johnson Bayou Rocks !! |
Sabine or bust
|
^^^^ what they said - there are no fish on BL - fish are jumping in boat on Sabine!

Don't need weirs when fishing Sabine and on beach

A few points of science may help people understand why how many fish they catch may not always be closely related to the health of the estuary. Back in April and May, there were lots of complaints and concerns that the sky might be falling because trout fishing was slow and the weirs had not been opened as often as some had desired. But there being few fish in the lake is only one of several possible explanations for low catch rates. More likely explanations (in light of available data) are that the fish had shifted patterns in pursuit of available forage and that the fish were not eager to bite what anglers were throwing at them. Most anglers develop their fishing habits for specks aimed at specks chasing shrimp, mullet, and croaker and also aimed at the propensity for larger specks to seek oyster reef habitat in the spring. However, the cool spring and destruction of oyster reefs made the specks less predictable this year. Shrimp numbers were down (cool weather and closed weirs), and manhaden numbers were up (pogey plant closing). Cooler water temperatures and higher salinities also lowered speck metabolic rates so they did not need to feed as agressively to maintain body condition. When we sampled fish condition in late May, the specks were in great shape, with an average of 106% of a healthy body condition. The fish were eating well compared with their metabolic demands. But we weren't seeing many anglers returning to the boat ramp with limits of fish. Limits of fish became more regular after the waters warmed up in June, because the increased metabolic demands of warmer water caused the fish to feed more aggressively. Some localized fish kills on bait may also have reduced the availability of age zero menhaden. There is a strong theoretical basis to believe that the number of days the weirs are open will have a significant impact on the condition of fish in the estuary, and in the long term, increasing exchange between the marsh and the lake are important and should have measurable effects. So far, we have four years of data. We can see the expected effects of temperature, salinity, oyster stocks, and interspecies competition in the available data, but the effects of the weirs are either too small to see or masked by confounding factors. This may be cleared up by additional years of data or access to LDWF data or by access to improved data regarding historical openings and closings of each water control structure. But for now, it is hard not to think that most angler complaints about the weirs being open or closed result from confirmation bias and the tendency of open weirs concentrating the fish in a predictable location so that they are easier to catch. Even a saltwater barrier or rocking the ship channel to maintain lower salinities in the lake will not produce the ideal trout fishery that is hoped for. Maintaining salinities below 10-15 ppt in the lower lake for most of the year would allow the weirs to be open for 150-200 days per year, but the lower salinities would also exert a high osmoregulation cost on specks which prefer salinities in the 25-35 ppt range. The specks in that scenario would face the trade-off between a higher metabolic burden to enter the lake and take advantage of the available forage from the open weirs and to remain in the ship channel and gulf which has a much lower metabolic burden. Salinities below 10-15 ppt would favor redfish, black drum, and gafftops in the lake, because these fish are better adapted to mid range salinities and would have a lower metabolic burden in the lake. Salinity levels below 10 ppt would be great for keeping the weirs open, but at these levels, the health of the oyster reefs would also begin to be negatively impacted. |
I'm goin to lighthouse cove in the am for topwater rapin

Thanks math geek. It's always good to read your posts.

The meeting is the 9th at 6pm.

I'll be there taking notes MG. May not be able to stay the whole time, but I plan on being there for the discussion of the weirs.

At the same time, I hope they are amenable to moving toward more data driven management based on salinity and water levels in front and behind. |

Not sure if anyone read it, but what pops out to me is that in 2009 they moved forward with Phase II of the CCMMP. Part of Phase II is managing for fisheries. This involves the slotted gates at Lambert and Peconi being opened for 1 to 5 days during each new and full moon event. Has anyone noticed this being done? Also, the boat bay is supposed to remain open, except when salinities exceed the 5 ppt limit at isohaline line No. 2. The management now is supposed to be driven by the isohaline lines. The problem is, most of those CRMS stations back there are not realtime. Some, but not all. This one is: http://waterdata.usgs.gov/la/nwis/uv...95231093100100. That is between the 12 ppt Isohaline line and the 5 ppt isohaline line. The salinity right now is above 12 ppt, so this is one reason the weirs are probably closed. Right now, according to the Phase 2 portion of the CCMMP, only the boat bay at Grand Bayou, the 6-inch slots on each weir, and a flapgate on the Grand Bayou Structure can be opened for fisheries purposes. They have adapted that in the document I posted above to say that the weirs will be opened unless the salinity rises above 5 ppt east of the 5 ppt isohaline line. Well boys, without any realtime data available, its hard to say if it is, but I would be those salinities are above 5 ppt. |
Where in the CS-54 report is the part about Phase II?
|
Uh, I'd have to pull it up again to find the exact page, but I believe it was under the hydrology section.
Now not all of that information I posted was in that report. Most of it came out of the resource management plan itself. If I can post a PDF (don't know if I've ever figured out if you can or not), I will post that. Its a 3 page document that outlines the management objectives and the objectives of each phase. |

Here it is. Couldn't do it from my phone. The isohaline lines are a bit difficult to see in the scan, but the 12 ppt line is closer to the lake, while the 5 ppt line is closer to Highway 27.

BTW, that is also in that report I'm sending you. |
They opening weirs today and meeting tomorrow
Lmao what a joke that system is !! And the people who run it So tomorrow they can say " he we opened them yesterday " |
Quote:
Serious question, W: if they could back up the closings with scientific data, defensible data, would you have an issue with the operations? |
So really since limits are so easy now do we love or hate big lake? Is it still going down the drain?

But I don't want to hear it from the guy who duck hunts back there |
Not enough BroScience in this thread. Can we get more memes and gifs please?

From what I've seen, he's not even going to be there. I don't think his name is on the program anyway. |
Now, I don't know Chuck, and I don't know if he is some how pulling strings, but being that he's the Public Information Director, I'll give him the benefit of the doubt, unless it is revealed that he does have some pull in the management of the weirs.
The ONLY reason his name is on that recording is because its his job to take flack from the public. He's a PR guy. They aren't going to put the name of a biologist on that recording. |
They need to take salinity readins 2 miles down grand not 10ft away from weir and they would be open a lot more

These 2 names were on the email I recieved today.

Did they send something new out? |

Where's my name????? I'm getting up there 2!

I had a loong conversation with Chuck Perrodin the other day, he definitely does not make the decision as to whether or not the weirs are open, he is not a scientest, he is a PR guy. He will be at the meeting (or that's his current plan) and will freely talk about who makes the decisions and how they are made. If nothing else you will at least be able to be mad at the correct persons. I also doubt if he hunts back there because when I was referencing different locations and bayous he was very unfamilliar with it.
