All good information. I'm going to try the easiest first, which is to let it fill with the rain coming (hopefully it will), and then turn the well pump off and see what happens. If it recedes to a point, I think I will add bentonite to some suspect areas that I think I have already identified. if it doesn't work, then I guess I have to drain it and start over. Has anyone had any experience with a liner? Sounds easier than compacting; and it is only 1/3 acre pond.

If I have to drain and compact, can anyone recommend a reputable pond excavator in the central Ohio (Dayton) area?
