Bill I am pretty sure my problem is DO. The lake winter killed almost every single year before I put up the first windmill. Also, DO measurements from last September came in really low. Pretty sure that is what I am battling. I still have a huge fathead population, but like I said even the crayfish seem to have winter killed. Not sure how bad things have to get for that to happen.I would also think that one windmill with two diffusers would have a hard time super chilling a lake the size of mine.

I am not sure how cold it gets up there, but I am going to find out for sure. I put up a Davis weather station this summer to get some wind and temp data. It will record all winter and I will retrieve the data next year.
