The Mississippi around New Madrid fault zone going dry?


Recommended Posts

Drought is over.  Whoppin 2 tenths of an inch today.  All of that blew away with the wind after the clouds left.  Still waiting to plant fall garden.

I would appear to me if that water wS goingbdown in the new madrid fault I would first have to go through what read was two miles of river bed . then if the fault decided to open up I do think  you sound have a absolutly dry river bed. q

I left the plug in my Jon boat overnight.  Sunk it on the trailer.  

How does 1.3" of rain turn into 10+"  in the bottom of a boat setting level? 🤔

High cfs?

Woah!   Just last night?   Wish we could have gotten that here.  Probably would have blown my trailer tires but I'm pissed cuz they are dropping this lake so fast for no reason.

Wrench, if the flow in cfs is wrong, chances are the level in feet also isn't accurate...here's what I mean:

They extrapolate cfs from the level.  If the level is x, then cfs is assumed to be y.  To check the correlation, they actually come and measure cfs periodically.  So as long as the SHAPE OF THE CHANNEL doesn't change where the gauge is, both should remain accurate.  However, if the shape of the channel changes in any way at that point, it will mess up BOTH measurements.  How can the shape change?  Floods can do it by any of several ways.  They may dump a lot of sand or sediment in the channel at that point.  Channel would get shallower, except the flow is still the same.  Same volume of water going past.  So that means the level rises compared to what it used to be at the same volume of water.  Or, conversely, the channel gets scoured out deeper.  Then with the same volume, the level drops.  Or say there is a riffle area downstream, and a pool at the gauge.  Riffle fills in more, forming more of a dam.  Level rises at the gauge.  Or the riffle gets washed out a lot deeper.  Level at the gauge drops.  Or the channel gets eroded to where it's wider than it was before.  Same volume going through a wider area means the level drops.

And every one of those scenarios, the LEVEL changes with the changed channel.  Volume is the same, but because the level changed, the gauge reads the wrong cfs, AND the wrong level in feet.  So until they come and check it, both readings are going to be wrong.  And this is a lot more obvious in lower water levels, because in really high water levels, the changed shape of the channel doesn't make as much of a difference in the level.

         Yeppers!

 One of the rivers that flows from the West is in minor flood stage and the powers to be are saying another four foot. Localized heavy rain or everyone in the Drainage coming from Kansas flushed at the same time, either way it will be up and back down pretty quick.

Wrench I have noticed that. It was fast almost like winter drawdown. Looks like they stopped today. It does not matter with these fish down here. I will be at them tomorrow evening 5 till dark
