All bottom areas should be compacted with whatever device that is being used for compaction. You dig a hole but it needs to be compacted well for it to hold water providing the dirt is proper for building a pond. Even with compaction many ponds leak due to poor building and compaction techniques. "You dig a hole, but build a pond." Holes never hold water for long.
If I need to get it compacted, then I will. Just gotta talk to the boss on the job site.
I am also going to get some soil samples of the clay, once they get to depth, so I can decide if I need to add lime/alum. It'd be alot easier to add it when she is dry.
I'll be getting some more pics tonight for ya'll.
Thanks again for the replies.
