The draw down was never about killing the grass as their the ones who put in there to start with. It was about getting all the bait fish out in open water so the predatory fish (big fish) could thin the numbers of stunted fish(bluegill and crappie) and make it a better pan fish lake. and it has helped, now as far as the grass goes it is a love/hate with me but if I can find a certain lure that they quit making back in the 70s I am sure I will like it better!
