My pond is still dropping about two inches per day. Can see any leaks in the berm and looked around pretty well today. Cool weather today and the last few days so i dont think too much is from evaporation. Going to fill the pond to the spillway again in the next few days if possible. I figured more pressure with it filled will cause more settling and possibly help seal settle or create a visible leak. Cant be two big of a leak or leaks or it would have drained by now. Will keep u all posted. Thnaks for the comments.
