Mine went down also as it filled. I could see the waterline on the side of my dam and was very concerned that it was leaking. Upon further review, examing the gov. soil reports for my area, the clay that I have will allow water to permeate approx 8" down. Also, the loose soil on the dam will absorb quite a bit. Let it settle and I think you will be OK.
