I bought some land and had a one acre pond built in late July. At its deepest, it is 13 ft. and now lacks about 4-5 feet being full. Novice that I am, I did not know that ponds leaked until I subscribed to POND BOSS and discovered this website. Now I am afraid that my new pond may leak. It has lost about one inch in the past week. How much is it likely to lose by settling, or by simple absorption? Thanks to anyone who responds.
