ewest,
In my pond, due to extensive shallows at full pool, it has probably lost 30%, and 20% from what I call "normal" pool. I like to keep it about 4 or 5 inches below full to allow for unexpected downpours to be absorbed without going over the emergency spillway. Just trying to get maximum growth out of my CC before I harvest some of them. I will try to harvest some within the next few days to see if they are really eating size or not. Probably would not get much more growth out of them by waiting a month.
