I live in south central MN. I do plan to run an aeriator all year. The pond will be mostly feed from ground water and is a clay sand mix. I'm also planing to use feild stones to line the north edge of the pond to help keep the shorline from washing out and clouding the water. Not sure if it will work. Sounds like I sould put pred fish in befor croppie if they spawn that well in MN ponds.
