In saying all that, TR's level is now 726.6. It has dropped 8 inches just today so it's on the way down fast. BUT with the rains now and tonight and tomorrow, it will head back up, but how much is yet to be seen.
Following this thought, the same thing will happen on Bull Shoals and at Bull Shoals Dam, as well as Norfork. The Corp will not release additional water until they have to- when the lake gets to the top of the flood pool. I'm sure there's exceptions to the rule but one thing is for sure- when BS's level reaches the top of the pool, and it will very soon, Bull Shoals Dam will not be a dam anymore, it will be a spillway, unable to control its flow.
Another scary thought- BS's watershed will change from it's normal area to the whole White River Water Basin because at that time, all the dams in the chain will be spilling their water thru the whole system. Now you see the potential full impact of this event.
