Wolf Creek Dam.

60,000 cubic feet per sec of water being released. They're hauling Rock and boulders the water is up so high that it's washing the bank out where the electric Transformers are

 

confirmed bringing in truck after truck of gravel and boulders building a wall

Had it reached 760, is that just an uncontrolled release over the top of the gates?


.

yes as far as I know..... the Corps have a poor history of being honest about the dangers of the Dam....this is why some people question them

muddy water near the power plant was a major concern in the past because that was a sign of seepage.....hopefully all the muddy water i pointed out the other day was just from the bank eroding

 

in a you tube video(see below) it said concerns in the past included muddy water in the tailwater,  sinkholes near the power plant, a wet stop on the opposite end of the earth part (way down from the dam, and river bank being unstable (not sure what that means)

 

The had a similar issue at center hill dam too which they recently repaired

'Unprecedented' water levels at Lake Cumberland raise residents' fears the dam will fail

eavy rains and flooding that have pushed Kentucky’s Lake Cumberland water levels to a record high are creating the biggest test yet for a dam that was considered highly vulnerable to failure before a $594 million repair was completed five years ago.

The rain-swollen lake on Monday forced the U.S. Army Corps of Engineers to release a record 58,730 cubic feet of water per second from the Wolf Creek Dam, causing some flooding along the Cumberland River in low-lying areas downstream.

So far the dam shows no signs of problems, said Corps spokesman Bill Peoples

 

Residents worry because in 2007, the Corps lowered water levels in Lake Cumberland amid fears that a weakened Wolf Creek Dam might fail and cause perilous flooding as far away as Nashville. The nearly mile-long earthen dam, built atop cavern- and fissure-riddled limestone, was shored up during seven years of construction.

“These lake levels are unprecedented,” Peoples said. “We’re confident that barrier wall is doing the job it was designed to do.”

The level of Lake Cumberland  peaked at 756.52 feet above sea level this morning. That’s about five feet above the previous high level set in 1984.  The US Army Corps of Engineers continues its record setting release of water through the dam at 58,740 CF per second.

just skimmed over them..thanks...will review more later

 

I did see that the old outflow record in 1974 was when the lake wasn't that high...perhaps they had different rules back then and never let the lake get as high as today?

I know on lake Travis (austin tx), last fall  there was a a huge flood....many people on local forums complained  that they let the lake get to high in the summer for recreational use these days.....

sounds like that are going to keep the flow at 58,700 for at least two weeks

Cumberland County Emergency Mgt. Director says they’ve having to take supplies to some folks by boat who are trapped in their homes because the rising Cumberland River. And it will be that way for 2 weeks because of the water being taken out of Lake Cumberland. More at 4-6 @WKYT

------------

example of the issue: if the lake drops  and average of .06 an hour for 2 weeks that only about 736 feet (-20 feet)

EURO keeps shifting the axis of heaviest precip more N...something to keep an eye on over next 72 hrs.

I hope you get your snow..but your area obviously doesn't need the precip

this 10 day period is the  "dry" time ...

models hint at a wetter SW flow returning in the 10-12 day range

Don't believe snow is happening south of 40. Models have overplayed the reach of cold all winter, don't think this is any different. Region hopefully doesn't end up of the battle zone with stalled fronts. Much more of a NW shift on modeling and even the Cumberland region will be in the axis with these next waves.

Cumberland at 5am 756.26  down .26 (or .01/hr) past 24 hours

the OHIO and Mississippi rivers are now moderate to major flooding in many places...on the lower MS..may not crest for weeks...

that is without any more rain factored in..

the NWS flood forecast for the  mid MS river came out yesterday....lots of snow in the upper basin..soil moisture and stream flow high..major flooding likley

going to be trouble for a long time

now there are 3 steps they will take to lower impacts if they have  to protect places like New Orleans and Baton Rouge but more on those later

got to get these lake levels down  ASAP..

need a drought

.the incoming rain won't help

Pic from Knox Mayor of a sinkhole just opened this morning in Powell 

D0WUkngWkAE6xfc.jpeg

My company is drilling this one right now and I am looking for the solution (lots of grout pumped under high pressure likely). Looking to be about a 150K fix!!

 

The amount of geotechnical issues caused by the amazing rainfall is insane... I have been dealing with mud flows in Knoxville... Mud Flows!!!

 

My office is located in Hardin Valley, just off Beaver Creek. We were very close to getting flooded. According to FEMA flood maps, the flood line was somewhere between the 100 and 500 year flood event (much closer to the 500). Just insane!

they are going to do step 1 today..the most common...open Bonnet Carré Spillway above New orleans

step two would be to divert flow at Red river landing above Baton Rouge ..The red river..( the one in Tx and Ok) used to flow into the MS river at that point....but now is diverted south into the Gulf...since the MS river is at a higher elevation they can divert alot of water there...

the third and most extreme is to blow the levee on the west bank right below Cairo IL...this floods much of the low lying area of the boothill of MO..they only have done this 2 times..last in 2011..and i think once in the 1930's..it can only be used once a season as the bowl will fill up

also see this article they said 1.250 million cfs per second is the flow that triggers step one..way down south

as of right now  a huge 478,000 cfs is coming out of Barkley (cumberland)and Kentucky Lake(TN basin) alone..the lakes are rising well above summers pools becasue inflow is still higher...Barkley is releasing 136,000 cfs into the OH/MS    Cumberland is 59,000 of that..

in a perfect would Cumberland would be releasing ZERO..and Barkley and Kentucky much lower

 

 

NEW ORLEANS (WWL-TV) — For the third time in four years the Bonnet Carré Spillway will be opened Wednesday to the projected flow of water down the Mississippi River, according to the Army Corps of Engineers.

According to the Corps of Engineers web site, this will be the first time that the spillway has been opened in consecutive years. The Corps anticipates opening approximately 38 bays Wednesday, possibly increasing it to 200 bays over time.

The Spillway is used to divert water flow from the Mississippi River and send it toward Lake Pontchartrain when the water flow gets too high.

Boyett says that projected flows indicate an opening in the middle of next week, likely Thursday, February 28.

The ‘trigger’ for an opening is a projected river flow of 1.25 million cubic feet per second, which is what the New Orleans river levees are designed to handle. Anything above that level means the spillway is opened.

The spillway has opened several times in recent years, including: 2008, 2011, 2016 and 2018.

Norris finally fell enough to reopen schools here tomorrow, though some roads are still closed. It's 10 feet above full summer pool. Even with the spill ways wide open they could only let water out at about 1/2 the rate it was coming in until today, when it finally dropped below the output. It's only supposed to fall 6 inches over the next few days though. Any more rain will be too much rain.

River Update: We are increasing releases out of tributary dams to recover flood storage in preparation for the next rain event, so you can expect to see above normal river flows below those dams. (1-3)

Further downstream on Kentucky Lake, we continue to work with the Army Corps of Engineers to control releases out of Kentucky Dam because of flooding on the Ohio and Mississippi Rivers. Water levels on Kentucky Lake could rise as much as eight feet above summer pool. (3-3)

CFS seems bring heavy rain back to region through March 

Looks like the rainy pattern continues....If this winter has shown us anything, we need to question things if a "dry spell" shows up in modeling.  Not sure that we get the massive amounts from last weekend, but still appears to be a steady dose for the next couple of weeks at least.  Honestly, when I start to squirm would be if we somehow manage to tap a tropical feed from a tropical storm or hurricane early in the tropical season.  Hopefully, we get enough time(before early summer) to allow the water management agencies to get our reservoirs down enough to withstand another healthy round of rain.  Very early in the season to have this much water.  I feel certain some folks are working long but productive hours to keep tabs on this.  They have done a really good, commendable job so far.  Just need to buy some time so that we can maintain a bit of wiggle room.
