Mississippi River heaving

Mississippi River going dry above New Madrid Fault – Crack in ground? River gauges/pics show the Mighty Mississippi River going dry! New Madrid related? [and from another] https://youtu.be/EjwjUkoAxEM September 29, 2017: 130 mile stretch of the Mighty Mississippi River from Tennessee to NW Mississippi is completely dry in places, so low making it impossible for barge traffic to deliver grain to the International or National markets. [and from another] https://youtu.be/I_XWW9CNWMU October 1, 2017: Has a crack formed in the bottom of the Mississippi River leaking water down into the New Madrid Fault? The Mighty Mississippi is getting very low, even bone dry in some places. No drought. Where is the water going? [and from another] http://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?Midwest

 

Is the mighty Mississippi so low above Memphis that barges can hardly navigate? Drought in the states feeding the Mississippi has very moderate, and does not account for the river depth in the Memphis region. The river is at a normal depth upstream at or above St Louis, IL. The temporary low water depth at Memphis is due to heaving in the ground there, stress on the New Madrid Fault Line, and this stress will come and go until the New Madrid adjusts. Temporarily, the flow of the Mississippi is being held back, a fact that is not notable as the water above Memphis is not at flood stage. 

Heaving land was noted during the last major New Madrid adjustment, when the river was reported to run backward. Rock strata being asked to rip on a diagonal will resist, and during this resistance will bunch up to create a heave. When the pressure to rip at a diagonal is eased, due to land elsewhere moving instead, then the heave relaxes and seemingly goes back to normal. When the quakes in Mexico no longer suffice, then the New Madrid Fault Line will itself begin making its move.
