I received same news last year in August and immediately began draining for the rotenone kill

Well there was one difference, a 20 lb channel cat. There were no intermediate green sunfish and few bass to speak of.
I was quite disappointed myself, however, I have learned more than I probably ever would have otherwise going through this process. So there is a neat side to it. I put lime in while the waters were down last fall, and I've got the restocking and fertilizing underway now.
Enjoy the experience! Now if you've done it all before, enjoy reliving it again
Good Luck with it!
