I have moved my aerator to a shallow end of my .5 acer pond for the winter. The pond is about 10' at deepest point. The aerator is in about 2-3' of water. We recently got a few inches of rain and then a big cool down the next day. My areator is keeping an 8'area open from ice. I noticed lots of fat heads along the shore befor the ice so I think my forage is good. Is there anything else I need to consider. Thanks
