Center Hill Dam Kayak Fishing Tomorrow

[Fishbus]

Looking to kayak fish tomorrow at CHD with my older 2 boys.

The TVA mobile APP still says sluicing, but they are no longer showing any discharge.

The predications from the USACOE site are as follows:

5-DAY DISCHARGE FORECASTS
WLCK2 2.7/ 2.7/ 2.7/ 2.7/ 2.7:WOLF CREEK DAM
DAHT1 0.7/ 0.7/ 0.7/ 0.7/ 0.7: DALE HOLLOW
CEHT1 0.4/ 0.4/ 0.4/ 0.4/ 0.4:CENTER HILL
PPDT1 0.4/ 0.4/ 0.4/ 0.4/ 0.4:J PERCY PRIEST
CORT1 3.6/ 3.6/ 3.6/ 3.6/ 3.6:CORDELL HULL
OHIT1 4.1/ 4.1/ 4.1/ 4.1/ 4.1:OLD HICKORY DAM
CHET1 4.8/ 4.8/ 4.8/ 4.8/ 4.8:CHEATHAM DAM
BARK1 13.0/ 13.0/ 13.0/ 13.0/ 13.0:BARKLEY DAM

So it looks like there is water being sluiced. What is the multiplier again?

Also, is the five day forecast starting "tomorrow" or is the first day "today"?

Thanks,

Billy

Here's about the best break down I have seen from Leo at Cumberland Transit:

the .7 means the average hourly discharge in cps, so .7 would be 700 cps per hour over a 24 hour period. (16800 cfs over 24 hours)

The sluice gate allows for 250 (+/-) depending on the lake level. so 24 times 250 = roughly 6000 cfs

subtract the 6000 cfs from the 16800 for 24 hours

They are sluicing in addition to the sluice gate while they generate and that is roughly 1500 cfs per hour per gate

so they will generate @ 10800 cfs approximately, one generator is about 3800 CFS if the gate is fully opened

divide 10800 by 3800 = 2.8 hours minus sluicing for 2 hours and it comes out to very close to 2 hours

when figuring that you have to take some things into consideration like assuming that the gates are fully opened when they generate or sluice and that the generation in cfs includes the sluice and that you have to subtract that out of the equation to figure how many hours they will generate. It isn't dead nuts on but it is very close and you can usually get very close on how long they will generate, just not when they will

Thanks Travis. Maybe I'll transpose that info into a spreadsheet to do the calcs for me!

When you use the unit CPS, what is that? Typo?

I copied if from Leo. I'd say a typo since the math works.
