So, your confusion is causing more confusion, since it's hard to figure out what you're actually arguing about.

Then let me try to clear it up…
The flooding was in the April/May timeframe up in Wisconsin and Minnesota. It is hard to imagine how a flooding event six months ago is affecting an area today, thousands of miles away.
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.
