What about Hatchell to Juban?

A little sunshine from a buddy on facebook. Not quite what you're looking for but I think it'll have to do.

quote:Difficult to tell since backflow is complex and probably not studied/modeled. But for that area it ultimately would be controlled by Manchac Point, since the tributaries that drain campus end up there. The magic number is 21.5'. A quick look at the topo shows me most of campus is around 23. So if the 21.5 peak makes it all the way upstream, it looks like it would get to the Burbank and Lee area. But again, this is unprecedented, dynamic, and complex, and that backwater wave may not make it all the way back upstream... Another complicating factor is more rain. If it storms again while the backwater is peaking all bets are off...
How close to campus do you think the Burbank/highland area will flood if the backflow happens?

Thanks. Been looking at that map all day and never thought about that.

Thanks for your post earlier

Someone asked about the squiggly base flood elevation lines. If I am correct, that is the line at which the base flood has been determined (the 1% every year, or 100 year flood) elevation at which the point will be underwater. If you live in that region and are above that elevation, you are dry according to the base flood. Below, you are flooded.

You can get base elevations off the flood map on the LSU Ag portal that has been linked.
I have a question about those base elevations. If your home's base elevation is significantly higher than a projected or possible crest for a near by river or bayou does that mean your home is proably safe? For instance, my base elevation is 36 feet, I live near Bayou Fountain. If it hits 21 feet, I should still be good, right? I just don't understand if the two measurements correlate.

More rain would be terrible, LSUJuice. These canals are incapable of draining anything right now.

How is Tigah Rag? He's close to the Amite right?
Posted on 8/13/16 at 11:22 pm to PhilemonThomas
Basically, look at the area your home is at and find the number in the squiggly line.
Now find out what your actual property's elevation is at.
Is it higher? You are more safe, above the 100 year flood line.
Is it lower? You are flooded.

Is the Country Club in trouble?
Baton Rouge Country Club or CCLA?
I think CCLA is going to get bad in a 3-5 hours - and I think it's likely some homes will see some water in them closer to Bayou Manchac.
Baton Rouge Country Club has more elevation changes. The area there near Ward Creek may have problems sooner than that. From the flood maps, the Fairway Drive side looks more at risk than the Brentwood side.

Any have a detail map showing the topography of southeast BR around Wards Creek, Bayou Manchac, and Bayou Fountain?

Super has done a great job of explaining what is happening and what is going to happen as the Amite crests moves south.
The key points are while DS is about to see the crest as you move south the crest is going to come later for those south. The further south your neighborhood drains into the Amite the later the crest will effect your neighborhood.
Jones Creek
Claycut Bayou
Bayou Manchac
All drain into the Amite in that order(North to South)
Second point is just because water levels dropped where you are in SE EBR doesn't mean it's over. Water will rise in lower areas to record heights.
Third no one has seen this before, and there are a lot of new subdivisions and complexes built in the last 15 years. There is no anecdotal evidence to rely on.
Watch area streams. Know your slab elevation. Get a rough idea if you could be impacted by looking at the 100 year map and adding at least three feet higher to what they show to see if you might flood.

Not good news...but thank you very much for replying to my post.
My dad has full coverage on his truck...so that will be covered. He does not have flood insurance on their mobile home though. Where they are located at in that trailer park...is higher than other areas of the park so I'm really hoping that and their trailer being several feet above ground...will be enough.

I still can't get over the fact that the 100-yr WSELs all over Baton Rouge are based off of these smaller watersheds and not the Amite.
EDIT: Not true. It's only the tributaries that drain into Bayou Manchac (Ward's Creek, Dawson, Duplantier, Fountain) that have maps that don't take into account the Amite. The rest of the Amite's tributaries to the north are good. Sorry for the confusion.

The gage may have a vertical datum it is referencing to (NAVD88 maybe). See if the flood map has the same vertical datum to be sure.
Many times river gages do not go by a specific datum but if they do, it should be specified.

Makes sense. Thank you sir (or madam)

Start moving valuables upstairs. Not kidding.
More than likely, the top of your slab is built up a foot or so from that number.....but there are areas higher than the flood plain see water upstream from the southern portion of Baton Rouge today. That's flowing south slowly. I suspect that will be the case in Baton Rouge as the floods back flow into the city's drainage system.
