Water levels do appear to be low in the Tennessee area which is affecting shipping. I did not see the location of the satay collected to generate the graph showing water levels in the lower Mississippi were normal. All I can assume is the satay was NOT collected near Tennessee.
The water levels in the New Orleans area are not lower than normal and they likely never are. The level of the Gulf controls those levels and I haven’t seen any reports that the Gulf is lower.
However, with lower water levels upstream, the volume of water flow is diminished which allows the Gulf to push up the river towards New Orleans. Recently, this salt incursion was found to be 63 miles upstream, close to New Orleans. This salt incursion is affecting the fresh water supply in the area.
It is a very long river. Different areas of the river are affected in different ways by the same drought conditions. Yes, there was Spring flooding in the far north but apparently that flooding six months ago was not enough to keep the river level high or the flow rate up today.

But there is flooding/high water levels upstream, even. now... That would cause an increased water flow, no?
And the chart I gave the link to included Memphis, and it stated the water levels were normal. T=hat would lead one to beleieve the "water flow" was normal, as well...
