Alright, with all the snow up northeast, will the COE drop the lakes below rule curve so they can hold it back more during spring or?

The snow up north has zero effect on COE lake levels. Most of the snow melts into the Mississippi River system, and it comes no where close to our lakes. Not sure where the snow in the Northeast melts into, though, but I'm pretty sure it won't affect our rivers and lakes in any way. My 2 cents, lol.
Hmm....I thought the entire purpose of the COE lakes was to have the ability to keep water OUT of the MS river to prevent flooding downstream.Quote:

Snow in the NE has zero impact on the corps lakes in MS. Some of it could affect on Kentucky lake and Pickwick depending on which rivers like the Ohio are impacted by snow melt. Most of that huge snow fall in Boston and that area is going to go in rivers up in that area and will drain into the Great Lakes or the Atlantic Ocean. Michigan,Wiscinson and that area will drain into the Ms and only impact us in Ms if the Ms river jumps up to high flood stages. Then they would have to start holding water.
I think the purpose is to keep the water out of the Yazoo, Yalabusha, and Tallahatchie rivers. The Yalabusha and Tallahtchie meet to form the Yazoo, which empties into the Mississippi at Vicksburg, way too far south to affect delta flooding. What water empties into the Mississippi at Vicksburg will have minimal impact on the Mississippi River before it empties into the Gulf. I think they are mainly concerned with the Mississippi Delta flood control, and that will be the Yazoo River, mainly. Like I said that is my 2 cents and only my opinion...........I am definitely no expert, lol.Quote:

Every field and road for miles around was under a few feet of water. I parked in the water, had to use my waders to get from the truck to the cabin. Once I was up on the porch I looked around and laughed...the Sardis dam was probably 10 or 15 miles away...but all I saw was flooding. I know nothing is foolproof...but dang...that was a lot of flooding for having a flood control dam just a few miles away. :yikes
those lakes you laught at have saved no tell how many acres from being flooded and no telling how many lives they have saved.
They were part of a massive flood control plan started after the 1927 floods. It included dams on the White River and it's tributaries and other rivers. The White River Refuge also figures into the plan as an area to displace some of the flood water.
There's no surefire way to prevent disasters, but it is a great help to save a lot of acres from getting wet
But its sad they still use the early 1970's flood as there guide. Because if we get that kind of rain again. No dam is going to help with the floods we will have again.
Do wish they would hold a little more water in the winter time. But then again they could care less about fishing. Same as TVA here at Pickwick Dam.
I guess what I was trying to figure out is IF they suspect the MS river has a high potential to flood say a month from now, would they allow the lakes to go below rule curve just as a precautionary measure to have the ability to hold more water back if necessary? Always amazed me how they can predict river stage levels downstream. Guess that's where all that fancy math I couldn't comprehend comes in.
They wont drop it below curve because of what the MS river may or may not do. Really they werent built to take the pressure off the MS but to take the pressure off the river bottoms below the levies. 2 inches of rain in a 24 hour period is an automatic shut down at Grenada because of what will happen down stream several miles. They are actually holding Grenada rite now a couple feet above curve, why? Who knows?
Copy on that Rees.
most likely backed up from the river . Gates close with 2 inches in a 24 hour period . Outlet reduced with 2 inches within 8 hours .Quote:

The same thing happens across the river with the only place water can get in the Mississippi is the Arkansas River.
