Sorry l got side tracked for a minute midtnviper back to your pond.Sounds like a lot for evaporation, we just finished a 2 acre pond in hickman county and it is just a catch pond, it probably has 2 or 3 foot of water in it and i would say it lost 2 to 4 inches due to evaporation. With all that said it sounds like there is a leak along with the evaporation.
