Our dog makes sure the pond stays clear of the damn geese. If its too cold for him I scare them off with my super soaker smile works great. We've had at least two landing every night since mid march. I don't let them stay at all as soon as we see them we get rid of them. They are everywhere here. There is a flooded field just down the road that has at least 100 and a couple swans and ducks as well.
