Point of Interest to those with ponds who want to keep geese from crapping all over everything:
Let the grass/weeds grow from the edge of the water to about 4ft inland. The geese will land in the pond (sometimes) but won't come out of the water since they can't see if there are any predators hiding in the tall grass.
Much cheaper then hiring dogs to chase them off or get the depredation (egg shaking) permits.
