Hi, Bob here not sure how it would work, I have an evcavated 1/3+ acre pond with a 4 ft wide spillway and found out this year with all the rain we have had that I had to put a screen across it to keep the minnows and 2 inch or less bluegill from going over. The first hard rain must have had about 75 little gills go over but the daughters had fun rescueing them so yes it is probably quite possible but you have to look at the overflow situation. But will add none of my channel cats went over the spillway.
