I have never heard that in my life! Even if they "could" stop every ounce of water at the Pickwick dam...there is another 300 creeks and rivers (maybe more) dumping water between Pickwick and the Ohio. I've heard "the cows are standing", "the sticks are floating vertical". I have a group of friends who will testify: "there on the rocks", "there on the wood". I always reply that "there under the water."
This is a "no". One time I was fishing a 400 acre lake, in Stuttgart AK, that was used for duck hunting. It was loaded with bass. The grass was thick and a little hard to fish so and I started fishing a set of spooks I got from "Lure for Cure". About 50% of the time the fish would just knock the spook out of the water...it was like they were just having fun.
