That was my problem, and why my pond leaks, despite excellent clay. I was not yet on Pond Boss, and let the dirt guy, who has built many ponds in this area, do it as he wanted. He used the bulldozer to "walk in" the entire pond bottom. If I had him use his backhoe with loader full of clay to do it instead, the compaction would have been better. A sheepsfoot roller cannot be had as a rental in this area, and only the large road construction companies have them. Hopefully, with some big rains, I will eventually get some clay settlement. Most ponds in this area eventually do seal.
