It's been awhile since I've posted, but I have been kicking around the idea of a windmill on my 3/4 acre pond with a max depth of 12' depth. My pond fluctuates in height depending on rain (not sure if I'm loosing any to saturation vs evaporation). I would like to be able to keep the pond fuller depending on how much I can get it to pump, but am I better off with a aeration setup and let the pond loose water. or go with a windmill water pump with a solar aeration. I guess I am not sure if a windmill pump will actually be able to keep it full or if I should just get a regular well dug with electric pump to help keep it full. thanks
