Was on the phone with a fishing buddy yesterday and they said they heard that they found a sinkhole in the levee at Sardis and was not going to allow the lake to reach pool until this was fixed. Have any of you guys heard this? I know I haven't seen anyone say anything about it on here. Just seeing if its true.

No sweat thats where Billbob had his camper parked.
This is not uncommon.
I know that there was a big crack in the emergence spillway. Been working on it for some time. Haven't heard anything about the dam proper.
if this is true, and they have to work on the dam. I sure hope you guys have better luck with the fix than we did here in Ky. they have been working for the last 6 years trying to repair a crack in Wolf Creek Dam, that holds the water in Lake Cumberland. they dropped the water level on Cumberland so much, 40 ft or more. that every year the water temps get so high that it has caused a fish kill, most of the large fish, Striper, Walleye, and bass just die and float to the top. I'll be to old to fish before Lake Cumberland, gets back to where it was 7 years ago.
I've known it for years. Nothing new.
A joint in the tunnel came lose and washed out a good size hole around it. They would shutdown the tunnel, backfill the hole with corn and seal the joint with concrete. The last repair was a couple of years ago. I think we had a camp n fish during that time. It took twice as much corn as the last repair 8 years before, 5 truck loads and is not holding. I talked to an engineer at that time. To much sand was pumped into that area from the lower lake when they built the dam. The right repair will be digging up that section of the tunnel and building a new one. They are waiting for the money to do that is what he told me.
Never knew why they working on the spillway. Thanks for posting, Canebreaker.
I called the corp and they said this was just another rumor locals started to try and keep the Missouri boys out of the lake!

you may be talking about a "sandboil" not a "sinkhole".....years ago working for an engineering company in Jackson we were involved in the design of the levee for the Ross Barnett Reservoir....I saw some of these after it was built and some were anticipated....here is an exert from the web describing this....
Abstract : A common problem during floods along the lower Mississippi River is the formation of sand boils on the landward sides of levees. If the hydrostatic pressure in the pervious substratum landward of a levee becomes greater than the submerged weight of the topstratum, the uplift pressure may cause heaving and rupture at weak spots with a resulting concentration of seepage flow in the form of sand boils. This, in turn, can lead to piping and instability of the levees during critical high-water periods. The disposition of pervious versus impervious floodplain deposits beneath the levee and the angle at which such bodies are crossed by the overlying levees are controlling factors in the localization of sand boils. Thus recognition of alluvial landforms forming the riverbanks, the types of soils association with them, and their detailed mapping in plan and profile are important factors in levee design. Corrective design involves: (a) detailed delineation of the surface and subsurface geology (b) careful selection of borrow pits to avoid stripping critically thin topstratum deposits, and (c) the use of riverside of landside berms of blankets and/or the installation of relief wells.
Does that have an English translation?
does not need a translation lol.....Officials at the COE office at Sardis are saying it is a rumor
Saw em coming thru Memphis yesterday afternoon saying they heard the hole sucked up their buddy's boat.Quote:

I also heard that the corp of engineers is working on a giant expanding log, similar to a feminine product that will actually expand when wet and seal off the hole. Man I hope it works!! If not, pole limits will be the last thing to worry about.
Local guy called me this afternoon and said if they can't get it plugged, they're gonna ask for 2 pole limit, 15" MLL and creel of 10 for lower lake.
