Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Pond leaks - Need advice

I don't know enough to give you a time estimate. It will all depend on how sloppy the bottom of the pond is. I wish Tim Pinny (Oklahoma), Mike Otto (Texas) or some of the other dirt guys would see this and chime in. Both of those guys have their own dirt moving business and work with ponds. Otto is one of the founders of this forum.

Clay has to have a certain consistency (i.e. water content) to properly compact. Too wet or too dry and it won't work as well.

You are right about the procedure. Spread out 6" of clay, switch to a sheepsfoot roller and roll the snot out of it. It's properly compacted when it starts to walk up and out of the dirt on its own. Switch, equipment, lay down another 6" and go at it again.
