It looks like it might be warming up, so we did a few project that were easier with 12" of ice. 1) put a pile of rocks near a point to enhance habitat, 2) put together a stack of choke cherry and brick weight for structure, 3) added a duck box (in 2-1/2' of water). The ice meant we could use our small utility tractor. Great Day! I have also include a picture of the winter aeration we are doing at the dock and outlet using a compressor at the house and 300' of 1" black PVC out to the pond, with virtually no pressure loss.
