Reply With QuoteI've been asking myself the same question and I'm not real sure how they will do it. The big C can roll some H2o when the spring rains hit and they will for sure. BTW welcome to our site there is alot of good info on here, you will enjoy it.

This is my first post so bare with me.A friend and I were discussing how they were going to hold the lake at 680 as their level for safety.My question is if 2inches of rain ,that is the amount I have heard,raised the lake 7ft. in about 3 days and their lowering it at a rate of about 6 inches per day it will take 20 days to get it back to 680.What are they going to do with the rains that could very well be coming at a rate 2 times per week or 3 days in a row and back to back weeks equaling 6 or 7 inches of rain for instance.To me that could raise the lake 20 feet and I am curious as to how they can deal with this issue if we have a rainy spring.I havent seen anyone really talk about this and I am curios about your thoughts.

The 680 is the target level the lake can go higher and they will adjust the generators to what the downstream flood plain can bear until back at 680.
It is still a flood contol resevoir and will operate as such.

The problem with maintaining 680 at C-land, is that they will probably flood Dale Hollow, because of C-land being priority for water release. The Corp has already informed the marina owners that Dale will be held at least 4 ft over summer pool all summer. The lower parking lot at Hendricks Creek will be gone !. That's tough to deal with, as parking there is very limited anyway. The lake is very close to pool right now, I think it will be a lot more than 4ft over, unless they let C-land go higher.

I don't know how it will affect Dale Hollow as it is not on the Cumberland River.
The only difference in how they manage flows when it rains is that when it does flood, as it did last week, they will aggressively pull as much water as they can to get back to 680.

Dale Hollow does end up in the Cumberland river at Celina. That is why it will effect Dale this year.

The 7 ft raise was the result of a little over three inches of rain in a 36 hr period. The difference in this year and years past is as soon as they see that the rain is falling they start to let it out. In the past they would allow it to raise 15 -20 ft and then start to release the water.Originally Posted by Cherokee082465
Also don't want to sound like a smart-*** but in order to drop the level 7 ft and it is falling 6 inches a day it would only take 14 days not 20. 7 ft divided by 6 inches equals 14 days.They can put 30.000 cubic feet per SECOND thru that **** . That is a lot of water.
Also the 680 is a target level It will vary up or down . They just don't want to put the pressure on the **** that a 20 ft raise does as in years passed. Also if they have a 10 ft raise it is still alot less water than if the levels where at 710-720

It may be an indirect affect. Dale is not on the Cumberland, does is on the Obey, a tributary of the Cumberland. If they are pulling hard at Wolf Creek dam, they cannot pull as hard at Dale or it will put the Cumberland River higher than they want.

jbyrd i didnt need a math lesson,spelling lesson or another smart*** in my life. I am looking for friends and to share ideas so get over yourself.

Umm with all due respect he apologized BEFORE he gave you the math lesson. Beyond that is the fact that while the dam is in bad shape it is no where close to the situation we had 30 years ago. The dam can take water up to 720 and beyond, without any real problem, this is a safety factor that was mandated and politically pushed by the folks downstream.. AKA Nashville.
However I agree with the assessment and the pressure from down stream... better safe than sorry.
The 680 level was set based on what the dam can hold with inflow in the spring with the spring rains. It can go up to 720 with no problem... the problem comes if it goes higher and there is TONS more pressure put on the dam for each foot it rises...and on the repair work. It also keeps the lake below the equipment that they are using to do the repairs on the lake side of the dam. Otherwise they could have left it higher.
NOW another lesson for ALL... Let your friends and neighbors know that while the dam is being repaired at an accelerated rate there is no danger of it failing to the point of any one being harmed at this time. There is plenty of water for recreation, and they should NOT stay away from the lake. The business folks down there need for people to understand this.
I have several clients who are being hurt by the silly nonsense the papers and TV reporters are reporting. There is no need for economic damage at all if folks will use the lake like they have in the past. There is no reason they can not use the lake after memorial day and the fishing in the lake will be better.
The businesses below the lake are in no real danger and the alarm system will provide at least a 5 hour safety window and that is if the dam just falls down which the engineers do not feel it will do.
The most likely scenario from the COE is that a leak UNDER the dam would start to drain the lake. It would create a whirl pool in the lake like a drain and it would take several days for the lake to drain. This would raise the river levels but should not cause death and destruction like the news media has talked about.
The media is talkign about WORST CASE scenario's and the COE has to plan for those.. but the Corps own reports state that the WORST CASE is less than a 1% chance.
Still the dam is in better shape than when they started to fix it back in the 60's. Nothing happened then and there was visible leakage and the dam was DAYS from failing.
We need the Ohio Navy and the rest of the vacationers to come to the lake and have fun. IT WILL STILL BE OVER 30,000 Acres and will still have more water in it than Kentucky Lake... (By volume not acrefeet) There will be plenty of places to camp, things to see, and places to explore.
PLEASE get the word out that Lake Cumberland is in good shape for recreation and that while the dam does need work it is not in any real danger at the PRESENT TIME..
Should that change there are mechanisms in place to evacuate any and all folks from the lake and below the dam.

Wasn't meaning ANY disrespect towards you or your math. JUST that I live here and am sick and tired of hearing all the bull about the lake going dry.All the folks who want to sit back and say what bad shape the lake is in (and I might add don't see it everyday) need to be corrected. Cumberland is still over 90 ft deep in some places., Yes the heads of the creeks are dry ,but the boaters and the skiers didn't need to be there any way. SO whan I see or hear anything that I know is false I try to point out that it is wrong.If more people did that then MOST of these rampid rumors wouldn't go any farther than the one who started them.
Also if you don't want me as a freind for that reason your loss. Life is too short to worry about such petty things.
Have a nice day

I just wanted to reply and apologize to you and anyone else for taking your lesson the wrong way.I should have laughed and let it go .I have read this board for a long time and enjoy it ,I hope we can put this behind with no hard feelings.Fishing and friends are more important than ''petty things''. sincerely,Ricky Smith
