You can't fix stupid! I had a meeting with guy one time that had two ponds. One was at the bottom of a hill, the other was about 100 yards up the hill and 12 feet higher in elevation than the first pond. I even shot the elevations with a laser level just to make sure. The guy wanted a ditch from the lower pond to the upper pond so that he could fill the upper pond. I thought I was mis-understanding him, but he swore up and down that if I put a ditch in between the ponds, water would travel from the low pond, up the hill, to the higher pond. I finally just walked off...I never could convince him that water would not run uphill.
