hmmm...OK but, that still leaves me with the question of shutter-type systems like mine. I could completely close all my shutters and the water would (after a couple of weeks) rise 3 feet and then begin to exit. Or, I could remove all my shutters and the water would immediately exit and drop my pond by more than 3 feet.
I've got it about in the middle right now...am I 3 feet above full pool or 3 feet below?
