Bad blood between Toledo bend and lower sabine

That would lower the level below what they are allowed to open the gates at. It sucks for the people below the dam, but they would have flooded either way

Under some situations..... IMO..... this guideline does cause the flooding to be worse down stream of the dam.


Example: If the lake is 1 foot below full pool level [172'] and it is raining very hard up just north of the lake.... to me, it would make since to not wait a day or so for the lake water to "hit" the magic level before the opening gates. If the SRA would open a few gates [or run the generators] before the lake rises to above pool level, down stream flood could be a reduced a little because fewer total gates would have to be opened.


The SAR guidelines need to be changed...... IMO to hopefully reduce some of the downstream flooding.

It really wouldnt matter. There is a ton of water coming from the north on top of the rain we have gotten down here. If the dam was not there, they would be flooded right now rather than in a few days like it looks like they will be. We have had ridiculous rain events the last few years. You could say we have had 3 500 year floods in that time. The MS and every other river in Louisiana will be flooding as well

You are absolutely correct!
