looks like we have a crest of 756.51 or so at Cumberland Clay Philpot 6 hrs · Edited Tony Wright I just found a video someone took today and paused it for a screen grab. Looks like they are making good progress.

facebook video on the ground yesterday... Darrell Littrell was live. on Sunday · 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

looks like a crest in the next few hours another pic of the river bank .....from a distance.....see all that white stuff near the transmission tower....gravel? sandbags? tarp?.also is the other pine tree gone? https://twitter.com/search?f=tweets&q=lake cumberand&src=typd edit: another picture has one of those non-pine trees laying on its side and a tractor putting rocks down so it seems they are tearing out all the trees and putting rocks down

take an hour ago Got to look fast but it looks like they have continued to shore up that bank...looks like more gravel is down and maybe a barrier? lots of gravel now hard to tell se 11 sec mark there is still muddy water coming off of it looks like

the NWS river gauge is still updating.. still .04 or .05 per hr from 11:45z to 15:45z.. https://water.weather.gov/ahps2/hydrograph_to_xml.php?gage=wlck2&output=tabular I'm not sure why this gauge is about 2/3 of a foot lower then TVA and Corps page... I have seen this lower report on several media/ social sites at times..the higher number seems to be the correct one in mentioned the PR's edit: 11am updated 756.26 inflow 81,000..otflow creeping up about 100cfs an now record 58,640

for some reason its not updating the Wolf Creek numbers.. but using the 6am number 756.07 time for more math... here is how dire the long term flood storage is... lets assume they keep the outflow at 58,000 for two weeks...will they? can they? lets assume inflow average 15,000 (likley higher) the difference is 43,000 divide that by that 7400 number it a fall of .056 per hour 1.34 feet a day in this unrealistic best case scenario the lake won't be back down to 740 until 12 days from now...Sat Mar 9th

Have you seen any info about what is going on there? any talk on facebook? I did see a pic that they have that area taped of with caution tape now..with a guard any new pics today might give more clues another interesting thing is that they turned the power plant back on (was zero outflow for days) and lowered the spillway outflow yesterday...any flow out of the power plant is less turbulent..but what were they seeing to lower the spillway outflow all of a sudden? also the tailwater is now high from the channel getting backed up, and getting higher( although is seems to be leveling out) .. higher tailwater=more erosion at what level does it flood the power plant?...same issues at Oroville when all the debris in the channel and increased flows backed the water up, almost lost power plant..lots of sandbagging and pumping http://riverstatus.usace.army.mil/group/LRN/Lakes/WLCK2-WOLF_CREEK

I agree and the situation may be grim: I will focus on Cumberland....rather then TN river...perhaps someone else could do that? 1) Laurel Lake is now full....now 3000 cfs was pushed thru the power plant at times...but the max inflow In these events were in the 10-15K range....with the 1800 over flow now and the power plant it is releasing about 5K outflow into cumberland....but with the bowl now full...if we have a repeat, 8-12K of extra inflow per hour would be flowing into Cumberland in stead of filling up the bowl it overflows at 1018.5 feet..it will fall below that but next time less space before it overflows 2) Cumberland lake looks to make it to 756 at least now....it is clear this evening there are worried about hillside erosion under/near the transmission towers..at outflow 58,000..any increase in outflow would increase that erosion..if that tower tips they might loose the power plant controls and./or the spillway gate controls...??? not sure about that though...went back and looked at the video...if appears they are trying to fill in the eroded area with gravel The had similar issues at oroville on the main spillway ...they were worried about back erosion cutting way at a vital transmission tower so they had to decrease outflow on the damaged main spillway..from 65,000 to 50,000 bfs and in the meantime the lake overflowed and went over the emergency spillway witch started back cutting that away....and almost eroded out the side of the Dam...in that case, since they had no choice, they increased flow to 100,000 on the main spillway to get the level level lower ASAP....the tower ended up being fine in hindsight 3) I mentioned this before but according to the math (at least at these levels) on the US corp page a .01 inch change in lake level hour is about 7400 cfs..for example if inflow is 100,000 and outflow is 26000 the lake would rise .10 that hour.. (100-26)/10 well the flip Side is true...if outflow is 60,000 and inflow ZERO the lake would fall .081 an hour...or 1.95 a day or 13,61 in a week.. well of course inflow won't be zero but in a week if that actually happened would only be down to 740 feet..of course that won't happen 4) max inflow in this event was over 220,000 Cfs.....without the Dam or flood pool...thats coming downstream next time 5) Dale Hollow and Center Hill very high too 6) any rain that falls later in the week will slow the fall of these lakes 7) Euro SE storm in day 11 ? see day 10..(then I assume dry after that)

it is indeed eroding the shore line and hat tree is indeed tiipped. over....in fact in this video there is construction equipment ,looks like they are trying to use grout .... transmission tower concerns? see at the 21 second mark'

oh boy.....Is all the outflow eroding away part of the embankment beneath the power plant? is that why the lowered it?...see this video taken today (or yesterday) maybe at the 48 second mark in the trees...and also see what appears to be a wet spot dark green above that. also I winder why they reduced flows from the spillway but turned the power plant back on?? edit: in the 2018 drone video there appears to be erosion there too...or at least more rocky then dirt edit again: did a tree tip over there from outflow erosion?

I noticed that too.....not up to the 60K predicted ..it could because 5K is going out of Dale Hollow now?? center Hill very high too going to be a long spring... Corps turns attention to drawing down storage reservoirs https://www.dvidshub.net/news/311799/corps-turns-attention-drawing-down-storage-reservoirs

Lake Cumberland lake at 754.48... stilling rising .. up .13 last hour outflow 55,000 ..inflow still 140K....peaked in the low 200K's!! inflow should match outflow sometime tomorrow...If it follows the slope graph of the other cycles this week.. here is a pic of the dam today and I noticed something interesting....notice what appears to be brown discolored water to the left of the power plant along the wall...after. that I will post a youtube drone video from 2018 (see 12 second mark) that also has the spillway gates opened...both after the repairs ....there is no discolored water in the 2018 video..... this discolored water could be seepage ..

media reporting it may be closed for a week

models trending wetter for the two systems later in the week..looks like 1 to 1.25 average wide but then huge highs after that?? cumberland now at 754.27 out flow now 53,000...still rising fast (about .15 foot/hr average) On the upper/mid cumberland other lakes such as Dale Hollow and center point getting closer to capacity..so very little flood storage for spring rains wolf creek Dam.. 6 feet from spillover when this was taken a couple hours ago. "spillover" is the gap between the road and the top of the gates,,hard to see here should fall short

taking the calculations to the past few hours... if you divide the difference between the inflow and outflow ..for every 7400 net difference the lake rises .01 feet per hour so the lake is at about 754 or will be soon...taking the opposite ..if there is 60,000 outflow and ZERO inflow that's a drop of .081 an hour or 1.95 feet per day... in a week that's a drop of 13.65 feet so if the lake magically stops rising at 754 (it won't , maybe crest at 755) and all the inflow magically stops (it won't of course) the lake level will be only be down to 740.35 feet in a week....any pattern change to wet after that would be trouble... the old record was set in May. after most of the wetter spring was over ...this is only Feb going to be a long battle and looking at the past 24 hours precip most of the basin did indeed get the gap in between the heavy Stuff in eastern TN .and the stuff further up into KY

Lake cumberland Lake up 3.88 feet 24 hours ending at 4am or .16 per hour average,,record outflow is occurring today increase today to 60,000 about noon less then 7 feet from spilling over..the increased outflow should slow the rise later..and inflows could be peaking about right now since it stopped raining.. 2/24/2019 3 AM 752.72 45,120 + .18 2/24/2019 4 AM 752.96 45,320 +.24 2/24/2019 5 AM 753.12 45,320 +.16

190,000 cfs inflow !!. where did you get this info.?...been looking for it online the outflow of 60,000 is exepcted later today...they are lucky they didn't get trained like Knoxville yesterday morning... like I said the other day they should have increased outflows earlier (25 to 35K-40) two days ago...If they would have done that ..60K wouldn't be needed perhaps thanks

NWS sites and TVA site is down or very very slow as of 500pm 4.54 at TYS according to climate report

The TN river At Savannah TN crest expected at 399.97 ..2nd highest crest on record the amazing thing is the crest of record was just 1.5 feet higher in 1897.....before the flood control the Cumberland basin may have gotten a minimum ..with more north and the heavy Eastern TN stuff SE

I posted about lake yesterday or the day before wondering if it was overflowing,,, of course that goes into Cumberland

Cumberland: out flow increased to 40,000 at 3pm. Level 750.52 an increase of .18 last hour 1.3 feet from record and 9.48 from overspill a kink in the convective system may Cause training up the river below the dam and then into the watershed got to be some heated discussions going on

WKYM 101.7 18 mins · According to a release today from the US Army Corps of Engineers, water is being released now at a faster rate than at any time during the 60 plus year history of Wolf Creek Dam. The largest amount of water ever released from the dam is 40,000 cubic feet per second in January 1974. Releases at Wolf Creek Dam have been increased to 45,000 cubic feet per second this afternoon, and releases are expected to increase to 60,000 cfs by noon Sunday, Feb. 24. Inflows into Lake Cumberland overnight were larger than forecast and the lake’s flood storage is quickly reaching its capacity, prompting water managers to move up the timetable for the increased releases. Impacts are expected in areas near the river downstream, especially in the Cumberland River reach in Kentucky from Rowena to Burkesville.

****BREAKING*** according to local media...They are afraid of Lake Cumberland overflow and now are dumping 45,000 cfs this hour and plan to increase it to 60,000 by noon tommorrow

Lake cumberland rising faster now...NWS guage data shows/predicts even more inflow then the other day..the River at Cumberland falls at this time is even higher then it was when those photos were taken...looks like 1 to 1.5 inches of rain feel over the past 36 hours....the steady moderate type at least they didn't get trained yet...could be they get lucky if the 2nd wave goes north? and they missed the knoxville stuff south 2/23/2019 9 AM 749.61 34,740 2/23/2019 10 AM 749.74 34,760 +.13 2/23/2019 11 AM 749.90 34,860 +.16

got to watch for any development of clusters (more heavy rain) ahead of the main line this afternoon with heavy rain...HRRR hinting at it NWS data is slow to update but 3.30 inches at Knoxville airport as of couple of hours ago edit: 3.59 now
