I have been asked several times how much water was being released at Wheeler dam during the last flood. The highest reading I saw was about 355,000 cubic feet pet second, give or take, with the spillways open. I will assume that this is an estimate by TVA and not totally accurate to the gallon, but close enough, considering the massive volume of water involved. Yes, I said "gallon" not cubic foot.
1 cubic foot of water = 7.48 gallons
1 cubic foot of water = 62.5 pounds
32 cubic feet of water = 1 ton
1 cfs = 7.48 gallons per second
1 cfs = 448.8 gallons per minute
1 cfs = 646,272 gallons per day
Now all you have to do is the math.
355000 x 7.48 = 2,655,400 gallons per second. That is over two million six hundred fifty five thousand gallons per second!
By comparison, that is more than the amount of water that flows over the combined US and Canadian Niagra Falls in the same amount of time!
Now let's do the math for a whole day:
24 hours * 60 minutes an hour * 60 seconds a minutes = 86,400 seconds per day.
86,400 seconds * 2,655,400 gallons per second = 229,426,560,000
That is two hundred twenty nine BILLION, four hundred twenty six MILLION, five hundred sixty thousand gallons PER DAY!
Even if this is an approximation, it is a HUGE volume of water!
Hopefully I didn't make any glaring mistakes in the math! (smile)
Good luck and good fishin'
