The Mississippi around New Madrid fault zone going dry?

Chief, it's so he can turn a little shorter without the tongue getting into the bumper.  Most of those old bumper mounted balls had marks on the bumper from jack knifing the trailer.

I always thought that was because they had bad aim backing up into the trailer.

I've seen this pic floating around for a couple of years now. 

Why he didn't put the ball on the bumper, I don't know. 

But there is no receiver on that truck so he made it work.

It is a Rube Goldberg fix for a 16' Jon boat on a 14' trailer.   Otherwise the corners of the bow will get into the tailgate on turns.

Drilling a hole in that hitch leg wasn't any fun I bet.

So are you one of those ball peen hammer Math challenged,  " I'll make it fit"  boat wrenches? 

If I take a measurement it is accurate to within less than .001"

Those clowns might as well just guess, because a 400cfs error is pretty significant.

The water flow rate is dependent upon the amount (volume) of water as well as the width of the channel that the water is flowing through. A thousand cubic feet of water travelling through a 20 foot wide channel will travel faster than that same volume of water travelling through a 40 foot wide channel. It is possible that even 1/2 mile downstream the river widens such that the flow rate drops 400 cfs. I'm not familiar with those sections of river. So this is just a possible reason for the differences that you see between those two values.

The current will increase with the narrowing of the banks.. but the amount of flow stays the same.  Gravity insists.   You can't alter the measurable CFS by throwing a stone in the river.

the basic hydrologic equation for flow is...... Q(flow rate in cubic feet per second)=Velocity(feet per second) multiplied be Area of flow(square feet).  Thus is the answer is cfs(cubic feet per second).  The only way to lose flow as the water goes downstream is to lose water along the way.  This does happen in floods when a levee breach occurs and you lose flow to fill up the flood plain.  But is won't happen in a low flow situation, 99.9% of the time.  As far as the original post of the flow of the Mississippi and New Madrid, no has mentioned the contributing factor of the Ohio River about 100? miles upstream of New Madrid.  The Ohio Basin has been influenced by the Tropical Systems.

I think we all agree a big quake would be a bad thing, but public preparedness would help mediate damages and loss of life, watching and trying to understand any water loss (if any) would prudent ....water loss into the fault system seem to make a big quake more likely ( lube effect like happens in fracking if indeed water injection truly causes the quakes)

All of the pics/videos on YT appear to be of side channels and backwater areas. 

I'd like to see an aerial view of the shallowest portion of the main channel.

the stage at Cairo is 20+ feet and rising https://forecast.weather.gov/product.php?site=NWS&issuedby=ORN&product=RVA&format=txt&version=1&glossary=0  Navigation problems don't even become a concern until Cairo gets around 5 feet on the gage.  And gage heights don't mean squat in relation to channel depths.  They are all independent based on arbitrary figures. And yes MOCarp, an earthquake on the New Madrid COULD be devastating to the River.  But if we had another quake like the 1800's one, the Mississippi navigation channel will be way down on the priority list.
