The Mississippi Basin

Here is a map of the Mississippi Basin, meaning the area of land which is drained by the Mississippi River. (the image is from the US Army Corps of Engineers)

I am thinking about it because this part of the world is going through yet another winter storm that the BBC is labeling a "Fast-falling snow storm"... I am not sure what they mean by "fast-falling snow". I did notice though that they write in the same article that "The storm will be followed by near-record low temperatures on Tuesday"....tomorrow...... It is a shame because the magnolias, the camellias, the daffodils, the ornamental plum trees and many other plants are all in bloom.

Anyway, originally I wanted to look at the map of the basin because I was thinking about how much water this is going to be once the weather warms up and the snow melts.
I would imagine that the Mississippi River will have major floods this year.
