Weirs
Todays Lake Charles paper, 6.94 inches of rain yesterday, 14.51 month to date, thats 8.4 inches more than normal this month and we are 2.69 inches ahead for the year, yet the weirs are still closed, what do we need to open? another storm

Guess we'll all find out in about a week and a half. The thing is, where was all that rain? That could be a rain gauge downtown. I guess if its coming from NOAA or something, it might be from the airport. I know there was A LOT of rain yesterday across the area, but has 14.5 inches fallen across the entire area for the month?
I can remember days where we got down pours at mom and dad's south of town, but pawpaw was saying they didn't get a drop in town. |

The rain we have been getting hasn't been popcorn summer downpours, the systems have covered nearly the entire state |

Its been sun shiny blue skies at my office in Baton Rouge, while it's down pouring at my house or at my wife's office which is about 10 minutes from mine. Like MG said, its all about the salinity. Doesn't matter what the rainfall is if it doesn't drop the salinity in the marsh. |

The big problem is that since the erosion of the land barrier between the lower lake and ship channel, the lower lake is much more strongly coupled to the Gulf of Mexico and has much higher salinities. The two attachments show the salinity as measured at Hackberry and at Cameron. Since the erosion of the land barrier and increased coupling between the lower lake and lower ship channel, the salinity on the lake side of the weirs is closer to that at Cameron than at Hackberry.
If the coupling between the lower lake and ship channel could be reduced so that the lower lake had salinities closer to Hackberry, then the weirs could take greater advantage of fresh water infusions and be open more days per year without allowing too much salt to enter the marsh. Salinity levels below 8-10 parts per thousand (ppt) present much less risk to the marsh than levels above 15-20 ppt, which is where Cameron (and the lower lake) have spent most of the month of June. |

7 inches on our rain gauge yesterday in 2 hours south of LC. From about jennings west to the border got the worst of it I believe. This was the 4th major downpour we have had at my house in the last month, but I can't speak for others.

Some of you guys should make the meeting on 9 July try and get real answers regarding whether weir operation is closely tied to measured salinity as it should be, and what salinity range in the lake is considered safe with respect to opening the weirs. |

That is a link to the realtime data for one of the CRMS stations back in the marsh. Salinity right now is about 14 ppt. Looks like some of the ones closer to the lake are about as high, probably higher. |

Mr Smalls, do you have any other monitoring sites that you could share? USGS 08017095 North Calcasieu Lake near Hackberry, LA USGS 08017118 Calcasieu River at Cameron, LA USGS 295231093100100 CRMS2418-H01-RT |

Just Google CRMS, or Coastwide Reference Monitoring System, and go to the map. I wish the LDWF left some of their stations set up that were right outside the weirs. I can't find any data on those, probably not set up anymore. I need to dig around on DEQs website again. I think they may have some stations elsewhere in the Lake. I used to have some data from those when I was working on my thesis. |

I just want them to show hard evidence that it's because of elevated salinity and not because of high dollar duck leases keeping grass.

Waltrip- What are the water levels like? It doesn't matter if the salinity in the lake is lower if the water level in the marsh is higher. It looks like that is not the case, so there is a valid argument for the weirs being open right now. |

Keeping closed actually does more damage to the lake and system Big money duck hunters run the gates and for that , they control the water

The salt is higher in the marsh than the lake right now according to a good source

Explain how, with the weirs closed, the salinity gets higher in the marsh than in BL. I cannot figure that out. Not a smart as question, just asking how. Sent from my iPad using Tapatalk |

Curious how Waltrip will respond. Please, no one spoil this by giving the true answer.

The marsh was already high salinity to start with and marsh was 3ft lower than lake Freshwater evaporates before saltwater That is why the marsh behind weirs is now higher than the lake
