Is this caused from a lot of Spring rain upriver or from the snow runoff?
Both this year.
Correct, everything follows down hill and poor Louisanna is at the bottom of the hill.
Whats Behind the Record Mississippi River Flooding?

This years massive flooding along the Mississippi River is the result of unfortunately timed rainfall and still melting snow. The overwhelmed river has already set several records, and more may be on the way.
This flooding is caused by “The Rising Tide of Racism in America”.

Global warming is causing the glaciers to melt and the oceans to rise, which causes the Great Lakes to back up into the Mississippi. /s
