Hi Dave.
From what I have read amongst the posts here, they tend to like the clorinated(sp) water. If it is closer than the pond IMO they would go for it before the pond. You could help to eliminate this possibility by placing a water source in your yard such as a bird bath or poultry water supply.
Or you could just go to the neighbors and tell them to let you swim on the hot days and splash around a bit, that way the bees stay away and you stay cool!
