Not sure about trees but when my neighbor and I straitened our common property line beside my pond and moved it about 12 ft towards his property I found that about 15 large oak,hickory and maple that were on his side of the fence moved to my side of the fence and being within 25 ft of my pond they became firewood! I did notice that my water levels went from a 1 inch drop per day down to 3/8 to 1/2 inch per day so I assume that the trees were soaking alot of water out of my 1/3 acre pond.
