I've got a tractor with a backhoe attachment and am thinking I would like to expand the pond we have on our Kansas farm by digging out the edges and working my way back. Yes, I know it looks like a lot of work, but for me it will be more playing than anything else and I don't have a timeline for completion.
Anyway, rather than draining the pond, which I just stocked with fish last year, I thought maybe I could dig the sides out and if it started to leak spread sodium bentonite. I don't think I will have a problem as the pond has no liner and appears to be just packed soil, although it is probably silted in so much it has lost a good 3-4 foot of depth.
But then not thinking I'll have a problem has gotten me into messes before.
