History shows again and again how Nature points out the folly of men.....

In your opinion how much of a concern is the extended length of this high water and it's affect on the levee system integrity?

It certainly is not good. the levees can get saturated and slough off or fail. Most of the lower Mississippi river has been above flood stage since the first of the year.

Just my scientific observations of water flow in ditches near my house, when the grass dies, the dirt is history.

Most of this. In the Mississippi river basin.

Need to quit P’ing in the ditch. Save our ditches.

I have noticed that many people that have used herbicides in their ditches have caused more problems than they solved.

I know of side by side neighbors where over time the herbicide treated ditch grew to 3 times the size of the neighbors trimmed ditch.

Identical water flow.

To add info

Predictions (see post 369 for link to predictions) are that we will see a slow fall starting in the next few days. A steady slow fall is better than a fast drastic fall. Less chance of saturated levee slopes sloughing off.

Failures are unpredictable and sometimes aren't related to saturation from high river water on the slopes as much as saturation from high, sustained rainfall, or even just poor foundation conditions. It's my understanding there is a failure on the West Atchafalaya Basin Protection Levee (WABPL) (call it the Henderson Levee for easy descriptive purpose) north of I 10. Not much water if any against the flood side of the levee in that area.
