Dave- Bill is as good as it gets so get his opinion. But with LMB and BM i would let her rip and not worry about it if he says it is ok. All i can tell you is that with Trout it is a NO NO this time of year, as you will mix the warm and cool water and have a mass loss of fish. Listen to Bill and Cecil they will lead ya the right way. I would do as they say and go slow. I am really curious "Bill" about he density of 02 in a mill devise vs. wave action. I always thought that the only way that a windmill would work is if the wind blew when you needed it most. Ya need to believe in the Almanac to use that syatem. Best of luck and all please keep this discussion going. I was even thinking about putting in a mill for looks only, but also as supplemenatal 02.
