That still begs the question as to how much water they use. I have a one acre pond with 8 bald cypress trees which are in the water year round. During this recent dry spell my pond lost more water than a neighbor's pool did. The pool is less than 100 yards away from the pond and does not have any shade over it, but it still only lost about an inch over a weeks time while my pond lost several inches. My pond does not leak so am assuming the cypress trees were drinking a lot of water each day to make up the difference.

When you are right, no one remembers; when you are wrong, no one forgets.
