Thanks Rowly! My best guess on carrying capacity in my lake would be 100-150 lbs per acre. This is based on water clarity of 3-5 ft right now, The amount of fish I have been catching and the size of the fish. Water temps are about 60 right now and the bloom is not quite in full swing (I hope) I would really like to fertize but since I just purchased this place, I don't know If I need to.I may wait till next year, after I have more time to see how this lake acts, so to speak. I don't want to do something I don't need to do and screw things up. Thanks for the reply! Good luck.
