Don how much do you feed in 10 acre lake per week.I am amazed that your water is so clear. I am afraid to feed over 20 lbs. per week. My back pond is a gravel pit with no water shed and fed only by underground springs. The water is usually green and you can only see in water a few inches at best.This year is better because it flooded last year. Do you have tfs in lake. i would feed more if i was'nt afraid of fish kill. the pond is down 39 inches this summer but this is pretty normal.I would love to have CNBG like you do.I will see how they do in the next couple of years. you have an awesome setup.
