"IF" they could start pulling the lakes back down @ 1ft/day ... RIGHT NOW ... this chart will tell you about how many days it's gonna take to get back down to Summer Pool : Louisville District Daily Lake Report

And in most cases, you're looking at 3-5 weeks !!

That chart doesn't include Cumberland (9ft over Summer Pool) or KY/Barkley (still about 1.5ft below Summer Pool ... Lake Levels in Kentucky, United States )
