Thank you for the kind welcome and your detailed response.

I do think I could get somebody in there with an excavator and pull the pipe from the dry side of the dam. I don't know if I could do it without being cost prohibitive. I would not want to have to drain the whole pond to fix the overflow pipe on the pond side. Right now it is a very slow leak. I wonder if they start pull the pipe if it would turn faster?

This part of Virginia is heavy red clay that makes for good damn material. I guess I need to find if there is anybody in the area that is good with pond work.

I was hoping that pipe could be effectively capped somehow.
