Thanks Bob Lusk for all your help. You see before I made the pond a little larger I last year had put drain tile down about 4feet away from the pond because it had a leaker and made the yard a swamp so I took that water away from the yard to the ditch. But now I will be ripping all that stone and tile up to make a good core trench but removing the stone first and maybe grabbing some muck I took out of the bottom of the pond to mix. Another bummer is that I have a willow tree at one end of the pond that may be a cause of the problem too but really can't remove it becuase it's close to the power lines and the roots are exposed in the water. Well at least I get some equipment time which I enjoy anyway. To get all this excellent info right I need to clarify that you are saying make the trenches in a rectangle shape instead of the oval shape that the pond is right. I mean it does make sense for retaining properties and pressures but need to be sure.
Bob Koerber thanks for the links and your homepage. Wow what a place you have there. I may be on my own here but am wonderign if you have any equipment pics working the pond like your track hoe that you mentioned and rollers or etc that you could share maybe on your website. Just a thought and I know alot to ask but hey don't we all like to play show and tell? I would love to post some pics but haven't even started to learn how.

I got teh publication and will be reading this for some time and thanks for the link because I actaully tried finding teh publication last night and didn't have much luck with the time that I spent. Although not toooo much. Talk to you all later
