Water now flows much faster to the Lower MS River due to changes in land use coupled with Corps of Engineers changes to the rivers.

Gravity is a fundamental law of nature. It makes rivers flow to the sea. If the natural flow is blocked, there are consequences.

The delayed consequences today are unnatural floods on the Lower Mississippi.
